    Introductory activity 4

    1) What are similarities in these pictures?
    2) Each picture represents an emergency situation. Attempt to describe the
    situation and what is being done
    3) What should be expected from a first aider?
    4.1. First aid
    4.1.1 Concepts of first aid, triage in emergency care
    Learning activity 4.1.1

    1) What do you observe on picture A and B
    2) Assume that you are the first bystander at car accident, how can you
    behave
    a) Concepts of first aid
    First aid referred as “Emergency aid” or immediate care is the first skilled
    [acceptable] assistance given to a victim (sick or injured) on the occurrence of
    accident or sudden illness in order to preserve life, prevent further injury and relive
    suffering until qualified medical care is available. For minor conditions, first aid care
    may be enough while for serious or complex problems, first aid care should be
    continued until more advanced care becomes available. The person who provide
    this emergency aid is called a first aider and has a responsibility to keep everyone
    involved safe while taking care of the victim.
    An emergency is a situation that poses an immediate risk to health, life, property
    or environment and requires immediate action.
    A Casualty or a Victim is a person who is injured or killed in an accident or in a war.
    Bystander is a person/witness who is present at an event or incident but does not
    take part.
    Triage is a sorting process used to identify the sickest patients or those at greatest
    risk of demise so immediate medical needs can be rapidly addressed. It is important
    to obtain a verbal consent before attempting first aid as most first aid activities
    involve touching to avoid causing offence or distress. A consent is an approval
    of what is done or proposed by another or an agreement as to action or opinion.
    However, if you encounter a confused casualty who is critically injured or ill, you can
    assume that they would want you to help them.
    b) Triage in emergency care
    Triage is an effective system that classifies patients into groups according to acuity
    of illness or injury and aims to ensure that the patients with life threatening illness
    or injury, receive immediate intervention and resource allocation. It can be a difficult
    decision to make as to who to treat first, however, you should work under the
    principle of acting in a way that gives the greatest number of people the greatest
    chance of survival.
    To meet its goals, the process of triaging considers the following questions and use
    START triage system to categorize casualties:
    • How sick or injured is the victim?
    • What is this victim’s potential for demise?
    • How quickly do interventions, care and treatment need to be delivered?
    • What is the evacuation plan after initial intervention?
    The START triage system
    “START” stand for Simple Triage And Rapid Treatment and is a simple way that
    allows rapid assessment of victims within 15 seconds per casualty/victim. It is based
    on respiratory, perfusion and mental status assessment.

    Self-assessment 4.1.1
    1) Why do we learn first aid?
    2) Briefly explain the START triage flow char.
    4.1.2 Principles of first aid care
    Learning activity 4.1.2
    1) Imagine you are a casualty in a road traffic accident. What would you
    expect from the attending firs aider?
    2) What qualities do you think should the first aider possess to be effective
    in helping casualties?
    Learning activity 4.1.2
    It is important that when engaging in the application of first aid that you adhere to
    the established first aid principles. Four basic principles and concepts underlying
    the practice of first aid are:
    a) Preserve life:
    The first aim of first aid is to preserve life, which involves the key emergency
    practices to ensure that the casualty isn’t in any mortal danger. Remember though,
    this includes preserving your own life as you shouldn’t put yourself in danger in
    order to apply first aid.
    b) Prevent deterioration:
    Once the first principle is met, as first aider your next priority is to prevent further
    illness or injury and or worsening of illness or injury. This can be achieved through
    keeping the victim still to avoid aggravating their injury, or from complicating any
    unseen issues.
    c) Promote recovery
    This encompasses steps the first aider follow to lessen the time taken for a casualty
    recover from an accident and aid in minimizing lasting damage and or scarring. For
    example, applying cold water to a burn as soon as possible to lower the chance of
    long-term scarring and helps speed up the healing process.
    d) Protect the unconscious casualty
    This involves placing an unconscious casualty into the recovery position to keep
    their airway clear
    4.1.3 Quality of First aid worker
    Providing an effective require more than just technical skills. Therefore, a quality
    first aider worker should possess several personal qualities and skills to be able to
    work under pressure and use common sense.
    a) Good communication skills
    Communicating with sick and injured people can be challenging. Therefore, a first
    aider should have excellent communication skills and a natural ability to talk to
    people. Communication is key to good casualty care and is very important when
    passing the casualty onto the next level of care. First-aiders should also take care
    to listen to any remarks or requests a casualty makes.
    b) Ability to work in a team
    First aiders are often required to work alongside members of the emergency
    services, especially the ambulance service; thus required to be good team player.
    c) Ability to work under pressure
    First aid situations can range from the mundane e.g. a small cut wound to incredibly
    stressful and demanding situation such as cardiac arrest. A first aider must always
    remain calm and assess the situation first before rushing to help the victim. This will
    help reduce the overall stress levels of the injured person as well as bystanders who
    may be concerned. Furthermore, it will help him/her manage tasks whilst having an
    awareness of the overall situation. Panic is likely to make the situation much worse
    and cause further distress and physical harm to the casualty as a result of wrong
    decisions.
    d) Good leadership skills
    First-aiders must ensure the removal of any danger from the casualty, or remove
    the casualty from dangers, and prevent the crowding of casualties by bystanders.
    A first aider may therefore have to take command of a potentially volatile situation.
    He or she may be looked upon by his/her colleges to provide leadership during an
    emergency. A first aider may also have to organize bystanders to assist in various
    tasks, such as moving the casualties.
    e) Knowledge of their own limitations
    A key skill of first aid is being able to recognize someone who needs quick
    emergency help. However, a first aider should know the limits of their skills and
    knowledge and be able to call for further appropriate help when required rather
    than try to do it alone. Calling for help should be done as soon as possible by the
    first aider him/her-self or by asking a bystander to do so if preoccupied by handing
    the victim. This will ensure that a medical professional arrives quickly to handle the
    situation in a more comprehensive manner and provide more specialist treatment.
    First-aiders should also understand that first aid has its limitations and does not
    take the place of professional medical treatment and that their responsibility ends
    when the casualty is handed over to the care of a competent health provider.
    Self-assessment 4.1.2
    A first aider was attending a multiple causality at the scene below. Comments on
    her intervention reflecting on what you have learnt regarding principles of first aid
    and qualities of a good first aider.

    4.1.4 Emergency gestures
    Learning activity 4.1.3
    With reference to “picture B” illustrated in learning activity 4.1.1) figure out
    what ABCDE approach involves for, for effective emergency care provision and
    attempt to practice what you see on model mannequin in skills lab.
    It is vital for a first aider to provide first aid in an organized and structured manner
    for all casualties that is following DRSABCDE sequence. DRSABCDE involve
    checking and addressing issues related to Dangers (for you as a first aider, the
    victim and others involved people), Response (a quick assessment to find out
    whether a casualty is conscious or unconscious), Shout or Send for help, Airway
    maintenance with cervical spine protection, Breathing and ventilation, Circulation
    with hemorrhage control, Disability and Exposure.
    a) Airway maintenance with cervical spine protection
    Check that a casualty’s airway is open and clear. If a casualty is alert and talking to
    you, it follows that the airway is open and clear. If, however, a casualty is unconscious,
    the airway may be obstructed. Obstructed airway dictates some lifesaving gestures
    to open and clear the airway namely jaw thrust or chin lift/head tilt as appropriate.
    Never move to next step until it is open and clear. for any known traumatic injuries,
    the cervical spine immobilization is required.
    b) Breathing and ventilation
    Check whether the casualty is breathing. If he/she is alert and or talking to you, he
    or she will be breathing, however you have to determine if the casualty is breathing
    normally through noting the rate, depth, and ease with which he or she is breathing
    which requires to look, listen, and feel for breaths. If an unconscious casualty is
    not breathing, the heart will stop. Chest compressions and rescue breaths must
    be started immediately. Note that a victim who is speaking full sentences is likely
    breathing is sufficiently. If the casualty is unconscious and breathing normally, put
    him/her in recovery position.
    c) Circulation with hemorrhage control
    Quickly estimate the patient’s heart rate and determine the quality of the pulse and
    evaluate the patient’s skin temperature, color, capillary refill and moisture to assess
    perfusion. Check for bleeding (absent or present, if present is it controlled or not).
    Injuries that result in severe bleeding can cause blood loss from the circulatory
    system, so they must be treated immediately to minimize the risk of a life-threatening
    condition known as shock. If a pulse is present and capillary refill is < 2 seconds,
    the patient’s circulation is likely sufficient.
    d) Disability
    Briefly evaluate the neurologic status and note any neurologic deficit. Any change
    in mentation from baseline should be concerning.
    e) Exposure
    Expose the casualty both anterior and posterior body surfaces and look for injuries,
    rash, etc., ask about recent exposure to infectious diseases note and address
    environmental concerns (hypothermia/hyperthermia).
    f) Recovery position
    Putting a victim in a recovery position is a frequent emergency aid gesture used for
    unresponsive victims who have open airway and are breathing. This position helps
    keep the victim airway open and allows any vomit to drain onto the floor preventing
    the victim from choking on it as well as from asphyxiation due to body position.
    Following are the steps for putting the victim into the recovery position:
    1) Put the person on the floor if he is not there already
    2) Remove the person’s spectacles if necessary
    3) Kneel down by the side of the casualty
    4) Make sure both victim’s legs are outstretched
    5) Place the nearest arm (the one on the side you are
    kneeling next to) at right angles to the victim’s body
    6) Bend the forearm upwards
    with palm facing up

    7) Lay the person’s other arm
    across his chest.
    8) Hold the back of this hand
    against his cheek on the side
    at which you are kneeling.

    9) Keeping that hand in that
    position, with your other free
    hand, grasp the leg on the
    other side of the victim’s body
    under the knee.
    10) Raise that leg, but leave the
    person’s foot on the ground

    11) Pull the raised leg towards you.
    12) In the meantime, keep the
    back of the victim’s hand
    held against his cheek. Roll
    the person towards you so he
    turns on his side.

    13) Position the victim’s upper
    leg in such a way that his hip
    and knee are at right angles.
    This will allow the victim to
    maintain lateral position.

    14) Tilt the head of the person
    backwards to keep the airway open.
    15) Make sure the mouth is
    angled towards the ground.
    This will prevent the risk of
    choking on blood or vomit.

    16) Adjust the hand under the cheek if necessary so that the head remains
    tilted backwards and the mouth remains at a downward angle.
    17) Do not leave a casualty alone and continue observing his condition and
    monitoring his breathing. If the person stops breathing, start resuscitation.
    Note:
    An unconscious, breathing casualty who is heavily pregnant, should be placed on
    their LEFT side so the weight of the baby does not put pressure on a major vein on
    the right side of the abdomen.
    Self-assessment 4.1.3
    In your groups go in the simulation lab and perform the ABCDE used emergency
    situation on model mannequin and attempt to put the mannequin in the recovery
    position.
    4.2.First aid in the selected common emergency situations
    Introductory activity 4.2

    1) Observe and describe each of the above pictures?
    2) Summarize the emergent interventions to a snake bite used in your
    community
    3) Which of the following are considered personal protective equipment?
    a) Gloves
    b) Mask
    c) Eye shield
    d) All of the above
    4.2.1 Burns
    Learning activity 4.2.1
    Outline the causes of burn you known.
    object, electrical current, radiations sources, certain chemicals and exposure to
    extreme cold. The burn is characterized by its appearance, its location, its extend,
    its degree and the presence of pain. Burns can vary from minor superficial burns to
    very deep burns that damage muscles, tendons, nerves, and even bones.
    First aid interventions in case of burn include:
    • Assess the situation quickly and calmly to get an understanding of what
    happened
    • Calm and motivating the victim to collaborate.
    • Ensure that the source of the burn has been dealt with, and the scene is safe.
    • Wear personal protective equipment, and get the first aid kit if available.
    • Gently remove any clothing and jewelry from the burned area. DO NOT try to
    remove any clothing that is sticking to it
    • Rinse the burn in cool or cold water for about 20 minutes. If the area cannot
    be immersed such as the face, towel, sheets or wet clothes that have been
    soaked in water can be applied. Change/rewet these regularly as they will
    absorb heat from the burn.
    • For small burn apply antibiotic / burn cream if available and the victim is not
    allergic to it
    • Cover the burn with a clean, dry non-stick dressing and loosely bandage in
    place. If this is not available or the burn covers a large area use a dry, clean
    sheet or other tissue material
    • Have the person follow up with a health care provider.
    • Do not apply ice to a burn. This technique will result in a cold injury on top of
    a burn and cause further tissue damage
    Note: Do not apply ice to a burn. This technique will result in a cold injury on top of
    a burn and cause further tissue damage
    Self-assessment 4.2.1
    Your classmate, was using an iron that is in its maximum warming up accidently,
    it /falls on his/her left foot cause a superficial burn. You are warned by a loud
    scream of pain. You jump to see what happen. What will you do to help him/her?
    4.2.2.Drowning
    Learning activity 4.2.2
    1) Observe and describe the picture
    aside.
    2) What can you do to help the drowned
    victim?

    Drowning is a type of suffocation induced by the submersion or immersion of the
    mouth and nose in a liquid. Drowning can result in death from hypothermia due
    to immersion in cold water, sudden cardiac arrest due to cold water, spasm of
    the throat blocking the airway and/or inhalation of water and consequent airway
    obstruction. You should not endanger your own life in trying to rescue the casualty
    from water; if possible use an item that floats to rescue the victim from water. Once
    the victim is out of water, turn him or her onto one side, open the airway and let any
    water or vomit drain out and if no signs of life immediately start cardiorespiratory
    resuscitation. It important to recognize early drowning victim’s distress signs.
    The assistance to the drowning victim should be initiated as soon as possible. Note
    that the chance for survival decreases as the time goes on. A drowned person
    rescued within the first minute has a 95% survival chance, only 25% survival chance
    if after 6 minutes, and these drop to only 3% survival chance if after 8 minutes.
    The first thing to be done is to Assist the victim to get out of the water by giving
    directions. However, as a first aider, you should not endanger your own life in trying
    to rescue the casualty from water; if possible, use an item that floats to assist get
    the victim to the dry land.
    Once the victim is out of water:
    • Turn him or her onto one side keeping the victim’s head lower than the rest of
    the body to reduce the risk of inhaling water.
    • Open the airway and let any water or vomit drain out and if no signs of life
    immediately start cardiorespiratory resuscitation (CPR).
    • Treat the victim for hypothermia that is remove wet clothes and cover him/her
    with dry warm blanket. If the person regains full consciousness, give him/her
    a warm drink.
    When giving the emergency aid to a drowning casualty you should aim to restore
    adequate breathing and keep the casualty warm while seek medical assistance and
    or hospital care. Note that any casualty rescued from a drowning incident should
    always receive medical attention even if he or she seems to have recovered as any
    water entering the lungs causes them to become irritated, and the air passages
    may begin to swell several hours later.
    Self-assessment 4.2.2
    Demonstrate how to position a drowning victim once out of water.
    4.2.3 Choking
    Learning activity 4.2.3
    A group of teen in your village are celebrating their achieving with a steak dinner.
    During the meal, one of them suddenly clutched his throat, with severe difficulty
    breathing and he was unable to speak.
    1) What do you think happened?
    2) As a first Aider, attempt to rescue him
    Choking is the result of either a totally or
    partially obstructed airway caused by swollen
    tissues or a foreign body. Food or other material
    entering the windpipe instead of the esophagus.
    Early recognition and intervention are the key
    to successful outcome. Choking should be
    distinguished from other conditions that may
    cause sudden respiratory distress but require
    different treatment such fainting, stroke, heart
    attack, seizure, drug overdose, among others.
    Signs of chocking range from mild to severe
    airway obstruction and these along the age
    of the casualty dictate steps emergency aid
    interventions.

    Universal choking sign


    a) Choking relief in a responsive adult or child
    Abdominal Thrusts also known as “Heimlich maneuver” is used to relieve choking
    in a responsive adult or child. Individual thrust is given with the intention of relieving
    the obstruction and it may be necessary to repeat the thrust several times to clear the
    airway. This maneuver should not be used to relieve choking in an infant. Moreover,
    this maneuver is avoided in pregnant or obese victims where chest thrusts are
    performed instead of abdominal thrusts.

    b) Choking relief in an unresponsive adult or child
    In severe airway obstruction, the victim will be unable to speak, cough, or breathe,
    and will eventually lose consciousness. If the rescuer is certain that that the victim’s
    condition is caused by a foreign-body airway obstruction the following steps are
    undertaken to help the victim.
    1) Shout for help. If someone else is available, send that person to activate the
    emergency response system.
    2) Gently lower the victim to the ground if you see that he is becoming
    unresponsive.
    3) Begin CPR, starting with chest compressions. Do not check for a pulse.
    4) Each time you open the airway to give breaths, open the victim’s mouth
    wide. Look for the object.
    • If you see an object that can be easily removed, remove it with your
    fingers.
    • If you do not see an object, continue CPR.
    5) After about 5 cycles or 2 minutes of CPR, activate the emergency response
    system if someone has not already done so.
    Note:
    • Sometimes the choking victim may already be unresponsive when you
    first encounter him. In this situation you probably will not know that a
    foreign-body airway obstruction exists. Activate the emergency response
    system and start high-quality CPR.
    • If the victim is pregnant or obese, perform chest thrusts instead of
    abdominal thrusts
    • You can tell if you have successfully removed
    an airway obstruction in an unresponsive
    victim if you feel air movement and see the chest rise when you give
    breaths or see and remove a foreign body from the victim’s mouth
    c) Choking relief in infants
    Back slaps and chest thrusts are used to relieve choking in responsive infant rather
    than abdominal thrusts through the following steps:
    1) Kneel or sit with the infant in your lap.
    2) If it is easy to do, remove clothing from the infant’s chest.
    3) Hold the infant facedown with the head slightly lower than the chest,
    resting on your forearm. Support the infant’s head and jaw with your
    hand. Take care to avoid compressing the soft tissues of the infant’s

    throat. Rest your forearm on your lap or thigh to support the infant.

    4) Deliver up to 5 back slaps forcefully
    between the infant’s shoulder blades,
    using the heel of your hand. Deliver
    each slap with sufficient force to

    attempt to dislodge the foreign body.

    5) After delivering up to 5 back slaps, place your free hand on the infant’s
    back, supporting the back of the infant’s head with the palm of your
    hand. The infant will be adequately cradled between your 2 forearms,
    with the palm of one hand supporting the face and jaw while the palm of

    the other hand supports the back of the infant’s head.

    6) Turn the infant as a unit while carefully supporting the head and neck.
    Hold the infant face-up, with your forearm resting on your thigh. Keep
    the infant’s head lower than the trunk.
    7) Provide up to 5 quick downward chest
    thrusts in the middle of the chest,
    over the lower half of the breastbone
    (the same location as for chest
    compressions during CPR). Deliver
    chest thrusts at a rate of about 1 per
    second, each with the intention of
    creating enough force to dislodge the

    foreign body.

    8) Repeat the sequence of up to 5 back slaps and up to 5 chest thrusts until
    the object is removed or the infant becomes unresponsive.
    d) Choking Relief in an Unresponsive Infant
    If the infant victim becomes unresponsive, stop giving back slaps and begin CPR,
    starting with chest compressions. To relieve choking in an unresponsive infant,
    implement the following steps:
    9) Shout for help. If someone responds, send that person to activate the
    emergency response system.
    10) Place the infant on a firm, flat surface and begin CPR starting with
    compressions with 1 extra step: each time you open the airway, look for the
    object in the back of the throat. If you see an object and can easily remove
    it, remove it. You should never perform a blind finger sweep in attempt to
    remove the foreign body as it may push the foreign body back into the
    airway, causing further obstruction and or injury. Note that you do not check
    for a pulse before beginning CPR.
    11) After about 2 minutes of CPR, if no one has done so, activate the emergency

    response system.

    Self-assessment 4.2.3
    1) A nine months old boy was playing with small block toys with his older
    sister, and suddenly became unresponsive and his lips turned blue.
    a) What do you think happened to the boy?
    b) As a first aider on premises, what will you do step by step to help this
    kid?
    c) What type of choking is the kid suffering from?
    2) What are specific considerations for relieving a choking 32 weeks

    pregnant women?

    4.2.4 Cardio respiratory distress
    Learning activity 4.2.4

    1) Observe and describe the pictures ABCD below

    2) If the victim is not breathing, how can you help him/her?

    A distress is an urgent situation in which a person is suffering or is in danger
    and therefore in urgent need of help. It requires urgent intervention to prevent
    worsening of the situation.
    The cardio respiratory distress is relating to the heart, the lungs and the airway
    passages and breathing muscles. Severe cardio respiratory distress results in
    cardiac arrest which can be witnessed or unwitnessed. Lack of quick interventions
    to restart the heart can result in serious complications such as brain damage which
    can be irreversible and the death follows in fact timing of intervention is crucial as
    the brain may die within 4 to 6 minutes without oxygen.
    Cardio Pulmonary Resuscitation (CPR) is the name given to the technique combining
    chest compressions, airway management, and rescue breathing aiming to restart
    the heart and is indicated when a casualty has no pulse, stops breathing or only
    gasping for air and becomes unconscious. To deliver high-quality CPR, you must
    begin high-quality chest compressions quickly, as these are considered the most
    important factor in giving the person a chance to recover. Compressing the chest
    circulates blood to the brain and the heart. High-quality chest compressions are
    delivered at a rate between 100 to 120 beats per minute and at a depth between 2
    to 2.4 inches (5 to 6 cm) in adult casualty.
    Fundamental aspects of an effective CPR include:
    • Immediate recognition of respiratory distress and cardiac arrest
    • Activation of the emergency response system, getting help and equipment
    • Early cardiopulmonary resuscitation (CPR)
    • Rapid defibrillation with an automated external defibrillator (AED)

    a) Steps in CPR

    • Place the victim on a hard surface,
    often on the ground
    • Check for responsivenessstimulate
    patient: tap the victim
    on the shoulder and ask if he or
    she is okay
    • Look for the chest to rise and fall,
    listen for sounds of air movement
    at the mouth and nose, feel for
    the breath against your cheek

    • Shout for nearby help


    • Check for pulse and breathing:
    this should take no more than 10
    seconds to assess for breathing
    and check for a pulse. If rescuer
    does not definitely feel a carotid
    pulse in adults and brachial
    pulse in children within that time
    period, rescuer should start chest

    compressions.


    • Open the airway
    • If no breathing or only gasping
    and no pulse, begin cycles of 30
    compressions and 2 breaths until
    AED is available
    • Chest compressions:
    • Kneel by the victim’s side
    • Place the heel of one hand in the
    centre of the victim’s chest.
    • Place the heel of your other hand
    on top of the first hand and ensure
    that pressure is not applied over

    the victim’s ribs.

    • Do not apply any pressure over
    the upper abdomen or the bottom
    end of the sternum
    • With your arms straight, press
    down on the sternum at least 5-6
    cm at a rate of at least 100 per
    minute (nearly 2 compressions
    each second) but no more than

    120 per minute.


    • After each compression, release
    all the pressure on the chest
    without losing contact between
    your hands and the sternum
    to allow chest recoil (chest
    compression and chest recoil/
    relaxation times should be

    approximately equal)


    • Minimize frequency and duration of interruptions in compressions.
    • Once chest compressions have been started, a trained rescuer should deliver
    breaths by bag-mask to provide oxygenation and ventilation at a ratio of 30
    compressions: 2 breaths in adults and a rate of 15 compressions: 2 breaths if
    2 or more rescuers involved (if 1 rescuer involved a rate of 30 compressions:
    2 breaths)
    • Managing the Airway:
    • Use a head tilt–chin lift maneuver to open airway of a victim with NO
    evidence of head or neck trauma.
    • Use cervical spine injury is suspect, open airway using a jaw thrust without
    neck extension.
    • Give breaths using a mask;
    however, mouth-to-mouth can also
    be performed (Should not be done in
    a hospital setting unless you have a
    barrier but can be used at home with
    family or people you know)
    • Use ambubag-valve-mask attached
    to oxygen once available:
    • Choose the right mask size to
    cover the mouth and nose

    • Give breaths slowly (over one
    second)
    • Watch for chest rise. Don’t overinflate,
    especially infants                                                                                                                                                    
    • Reposition if no chest rise                                                                                                                        
    • 5 cycles of compressions: breaths
    should be done in about 2 minutes                                                                                                                                           

    • Check for pulse every 2 minutes                                                               

    Note:
    • Rescuer fatigue may lead to inadequate compression rates or depth. Therefore,
    if 2 or more rescuers are available switch chest compressors approximately
    every 2 minutes to prevent decreases in quality of compressions. Every effort
    should be made to accomplish this switch in 5 seconds
    • CPR should continue and can be stopped when rescuers are physically
    exhausted or decision to stop is made by a doctor.
    • If you can feel the pulse and the victim airways are open and can breathe,
    put him/her in recovery position and continue monitoring the victim carefully,
    checking regularly the pulse and watching for signs of reduced air passage such
    as weak, ineffective cough, a high-pitched wheeze during inhalation, increased
    strain during breathing, clutching at the throat slight cyanosis.

    b) The automated external defibrillator (AED)

    An automated external defibrillator (AED) is a small,
    lightweight, portable and easy to operate device used                                                                                                                             
    to give an electric shock to restore when the casualty
    is having a sudden cardiac arrest. This device once
    attached to the victim analyzes the casualty’s heart
    rhythm and advise you what action to take at each
    stage. Starting CPR immediately and quickly using
    an AED improves the chances of survival.


    Following are universal steps for operating an AED:
    1) Perform CPR until an AED arrives
    2) Once AED obtained, turn the power on
    3) Expose the victim chest and attach the
    adhesive AED pads to the victim’s bare
    chest
    4) Clear the victim to make sure no one is
    touching any part of the victim, let the AED
    analyze the rhythm and wait until the AED

    tells you what to do


    Pads attached

    5) Follow the AED advice such as shock
    advised, no shock advised, continue CPR,
    check connection, etc.
    6) If a shock is indicated and other people are
    present, warn them to keep clear and ensure
    your body is not touching the person:
    7) Say, “I’m going to shock on
    three. One, I’m clear. Two,

    you’re clear. Three, everybody’s clear.”


    Clear the victim

    8) Check to make sure no one is touching the
    person or the AED then press the “Shock”
    button to give a chock
    9) Resume CPR with compressions for 2 min
    10) After 2 min of CPR, the AED will prompt you
    with further verbal and visual cues
    Pads attached
    Clear the victim
    Note:
    • The pads should be placed in a position that maximize current flow through heart

    (Sternum/apex or Anterior/posterior)

    • When no pediatric pads available adult can be used for children > 8 years old or
    weighing > 25 Kg
    • Ensure that victim is not lying in water and wet areas on victim are dried before

    using AED

    4.2.5 Fractures
    Learning activity 4.2.5

    Observe carefully the figure above and attempt to answer the following questions:
    1) What do you understand by fracture?

    2) Contrast and compare image A and image B

    Observe carefully the figure above and attempt to answer the following questions:
    1) What do you understand by fracture?
    2) Contrast and compare image A and image B
    Musculoskeletal injuries are common occurrences and these results into bone
    fractures (break or crack in the continuity of the bone), joint dislocation (the bones
    are partially or completely pulled out of their normal position), strains and sprains
    (injuries to soft structures surrounding bones). All of these injuries results in almost
    similar complaints. Use of x-ray is paramount to rule out fractures. Fractures are

    broadly classified as either open or closed fractures.

    Open fractures – also called “compound fractures”,
    are fracture in which there is an open wound or break in                                             
    the skin near the site of the broken bone. Involved bone
    is exposed at the surface where it breaks the skin but
    both sides of the fracture do not need to be visible.
    Closed fractures – are fractures in which the skin is
    unbroken although the bone ends may damage nearby

    tissues and blood vessels.

    Fractures can become life-threatening if there is severe internal or external bleeding
    and due to the risk of shock. If organs or major nerves or other structures/systems
    are also injured.
    Common signs and symptoms of fracture include:
    • Deformity, swelling, and bruising at the fracture site
    • Pain and or difficulty in moving the area
    • Shortening, bending, or twisting of a limb
    • Coarse grating (crepitus) of the bone ends that can be heard or felt (by
    casualty). Do not try to seek this.
    • Signs of shock, especially if femur or pelvis are fractured
    • Difficulty in moving a limb normally or at all (for example, inability to walk)
    • A wound, possibly with bone ends protruding
    First aid interventions in case of fracture should aim at preventing movement at
    the injury site (immobilization) and at arranging transportation to the hospital, with
    comfortable support during transit.
    First aid care for broken bones includes the following:
    1) Ensure the scene is safe and wear personal protective equipment.
    2) Apply gauze to any open wounds.
    3) Do not attempt to push the bone back in (if open fracture) and/or straighten
    the extremity
    4) Splint the bones in the position you find them in, never attempt to manipulate
    or correct an abnormally positioned bone or joint. Splints can be made by
    using magazines, wood, or rolled-up towels. Splint material are placed on
    either side of the injured extremity, supporting the joints above and below
    the injury and secure in place using tape or gauze ensuring they are not
    compromising blood circulation. The fingertips or toes in a splinted extremity

    should remain warm and pink.

    5) Use a triangular arm sling to secure arm and shoulder injuries
    6) Move the fractured body part as little as possible or handle gently to prevent
    making the fracture worse (e.g. a closed fracture may become an open
    fracture) and to lessen the person’s pain.
    7) Encourage further evaluation by a health care provider and avoid use of the

    injured part

    Self-assessment 4.2.5
    Referring to Images of learning activity 4.2.5, attempts the following questions:
    1.What do you think is the right course of action by the first aider? (Multiple
    answers are possible):
    a) Try to straighten the limb in image B
    b) Avoiding moving the victim
    c) Immobilizing the limb in the position he/she found it in by use of tree
    branches and clothes holding
    d) Pushing back the protruding bone in picture A and apply pressure
    dressing to control bleeding
    2.Using the knowledge and skills leant previously on bandaging, attempt to
    immobilize these fractures
    4.2.6 Hemorrhages

    Learning activity 4.2.6


    The body must have enough circulating blood volume to keep the body functioning
    and keep the organs supplied with oxygen. Blood is moved around the body under
    pressure by the heart and blood vessels. Without adequate blood volume and
    pressure, the human body soon collapses. When blood vessels rupture due to a
    severe injury, bleeding or hemorrhage, poses a threat. Note that hemorrhage is
    a feature of many presentations particularly, but not exclusively, those involving
    trauma. It is a loss of blood from damaged blood vessels and it may be internal or
    external. The aim of the first aider is to reduce loss of blood from the casualty.
    a) External bleeding
    External bleeding is usually associated with wounds (cuts, abrasions, amputations,
    incisions, lacerations and punctures). Serious wounds involve damage to blood
    vessels. External Bleeds can be categorized into three main types with regard to

    their origin:



    Record the time the tourniquet was applied and stay with the casualty and do not
    release tourniquet. Only a medical professional should remove a tourniquet. Help
    casualty into a comfortable position, if possible have him/her lying down. If the
    casualty becomes unresponsive and not breathing normally follow ABCDE.
    Note that blood loss often gets the most attention and many times the amount
    of bleeding is overestimated and draws attention to wounds when more serious
    injuries should be dealt with first. Therefore, whenever confronted with bleeding,
    perform a quick overview of the person to make sure something more serious is not

    being overlooked, the rescuer should be calm and reassuring.

    b) Internal bleeding
    Always consider internal bleeding after injury, understanding it cannot be controlled
    by the first aider. Internal bleeding is classified as either visible (where the bleeding
    can be seen) or concealed, (where no direct evidence of bleeding is obvious).
    Obtaining an adequate history of the incident or illness will, in most instances,
    give the first aid provider the necessary clue as to whether internal bleeding may
    be present. You should remember that current signs and symptoms or the lack
    of them, do not necessarily indicate the casualty’s condition. Due to the stealth
    of bleed, certain critical signs and symptoms may not appear until well after the
    incident, becoming apparent despite there being no visible cause, only when the
    casualty worsens.
    Visible internal bleeding is referred to in this way because the bleeding can be seen
    from:
    • Ears: Blood or blood mixed with clear fluid.
    • Lungs: Frothy, bright red blood coughed up by the casualty.
    • Stomach, bowel or intestines: Bright, dark or tarry blood coughed up by the
    casualty.
    • Under the skin (bruising): The tissues appear dark due to blood under the
    skin.
    In concealed internal bleeding, detecting internal bleeding relies on good observation
    and an appreciation of the physical forces that have affected the casualty. In these
    cases, the first aid provider considers the history, signs and symptoms. If you
    are unsure, assume the worst and treat for internal bleeding. Consider important
    observations that may indicate internal bleeding, which include:
    • Rapid, shallow, or irregular breathing
    • ‘Guarding’ of the abdomen, with foetal position if lying down
    • Pain or discomfort and/or swelling of the abdomen
    • Nausea and/or vomiting
    • Altered consciousness
    • Pale, clammy skin
    To help a casualty with an internal bleeding:
    • Call emergent help/ambulance
    • Wear personnel protective equipment
    • If conscious, lie the casualty down on their back with both legs bent at the
    knees and if unconscious, in recovery position with both legs bent at the
    knees
    c) Nosebleeds
    Nosebleeds are not usually serious though sometimes they can be quite dramatic
    and are often messy. They commonly occur because of dry air or high altitude, an
    injury to the nose, or a medication (especially a blood thinner such as warfarin).
    Blowing or picking the nose can also cause a nosebleed. People with nosebleeds
    often swallow a fair amount of blood, which may result in vomiting. Therefore, be
    sure to wear personal protective equipment and eye protection when attending to

    nosebleeds.

    Note: If a severe bleeding is not managed promptly and correctly, it results into a
    life-threatening condition called “Chock”. Hemorrhagic chock can result either from
    severe external bleeding, internal bleeding or both
    4.2.7 Loss of consciousness

    Learning activity 4.2.7


    Loss of consciousness we are referring to is synonymous to “fainting” which is a
    common reaction to a variety of conditions. It is the body’s reaction to the decreased
    blood flow to the brain that causes the person to pass out. Individuals may faint at
    the sight of blood, reaction to pain, exhaustion, hunger or during periods of intense
    emotional stress. Fainting also may result from long periods of physical inactivity,
    such as standing or sitting still, especially in a warm atmosphere. More serious
    conditions, such as an abnormal or erratic heart rhythm, can also cause fainting.
    Moreover, severely dehydrated persons may faint when standing up suddenly.
    Fainting is characterized by a brief loss of consciousness that causes the casualty
    to fall to the ground, a slow pulse and the victim become pale, cold skin and he or
    she is sweating.
    The rescue a fainted victim aims at improving blood flow to the brain and at
    reassuring the casualty and making him or her comfortable. When a casualty feels
    faint, advise him/her to lie down. Approach the victim and kneel down, raise his/her
    legs, supporting his ankles on your shoulders to improve blood flow to the brain.
    Ensure that the casualty has plenty of fresh air; ask someone to open a window
    if you are indoors. In addition, ask any bystanders to stand clear. As the casualty
    recovers, reassure him/her and help him/her sit up gradually. If he/she starts to feel
    faint again, advise him to lie down once again, and raise and support his legs until
    he recovers fully.
    Self-assessment 4.2.7
    1) Enumerate signs and symptoms of fainting
    2) Arrange the follow activities done to support a fainting uninjured causality
    in a sequential manner using the table below
    a) Continue CPR until help arrives or the person begins to breathe
    b) To reduce the chance of fainting again, don’t get the person up too quickly.
    c) Call our local emergency on 912.
    d) Position the person on his or her back.
    e) begin CPR,
    f) If the person isn’t breathing,
    g) Raise the person’s legs above heart level,
    h) Check for breathing.
    i) If the person doesn’t regain consciousness within one minute,

    j) Loosen belts, collars or other constrictive clothing.


    4.2.8 Snake bites
    Learning activity 4.2.8

    You were camping with your friends and suddenly one of them screamed “I
    am pricked by something on my left leg”. Looking around, you saw multicolor
    snake leaving your tent. Your friend leg present two puncture marks with parallel
    scratches on skin area he felt pricks.
    1) What do you think of this situation?
    2) What first aid care do think is need to help him?
    Many animals can bite or sting. Whereas most such bites and stings are painful,
    only a few types can cause sickness, allergic reactions, or death. Poisonous snakes
    inject a toxic venom when they strike their victim. It’s difficult to accurately identify
    a snake once it has bitten someone, as snakes are similar in shape and have
    many different colours, even within the same species. The effects of snake venom
    can take up to 2 hours to become apparent, so symptoms are not always obvious
    straight away. All snake bites are emergency and must be treated as venomous
    until proven otherwise and the bite may be painless and without visible marks.
    Do not attempt to kill or capture the snake that bit the casualty. But, if possible, make
    a note of the snake’s appearance to help doctors identify the correct antivenom.

    Take precautions to prevent other people from being bitten.

    b) Care and treatment
    The first aid principles for treating any kind of snake bite are the same. The main
    treatment for snake bite is the application of “Pressure Immobilization Technique”
    (PIT).
    • Follow DRABCDE and be prepared to perform cardio pulmonary resuscitation
    • Ensure the casualty remain as still as possible to slow venom travelling through
    the body
    • Keep casualty under constant observation and at rest and provide reassurance.
    • Apply the pressure immobilization technique (PIT):
    1) Have the victim lie down Stay quiet; do not move the bitten part. The more
    it is moved, the faster the poison will spread through the body. If the bite is
    on the foot, the person should not walk at all.
    2) Remove any rings, watches, or bracelets because swelling can spread

    rapidly.

    Note:
    • Keep the limb immobilized until medical assistance arrives
    • If only one bandage is available, start just below the bite site and wind as far up
    the limb as possible, ensuring to cover the bite site.
    • If no bandages, or splints available, improvise with clothing or whatever you

    can from the surrounding environment.

    • Do not wash the bitten area, as a venom sample may be obtained.
    • Do not elevate the limb.
    • Do not use an arterial tourniquet.
    • Do not remove the bandage once it has been applied, even if casualty is feeling
    well as long as there is no compromised blood circulation.
    • Do not try to capture or kill the snake.

    • Do not cut the bite and suck the venom out.

    4.2.9 Epilepsy
    Learning activity 4.2.9

    You live in place where a family has a kid who experiences seizures several time.
    1) The parents of that kid cognizant that you are an associate nurse ask you
    this question “what do you think to be the cause of that condition?
    2) What would you do when you find this kid in crisis?
    Epilepsy is a common cause of seizures. Seizures are a disruption of brain function
    that interrupts normal electrical activity of the brain. They consist of involuntary
    contractions of many of the muscles in the body. It is only when there’s a tendency
    for recurrent and major disturbances of brain activity seizures that epilepsy is
    diagnosed.
    No matter what the cause of the seizure, care must always include maintaining an
    open, clear airway and a monitoring of the casualty’s level of response, breathing,
    and pulse. You will also need to protect the casualty from further harm during a
    seizure and arrange appropriate aftercare once he or she has recovered.
    First aid management DOs in epilepsy include:
    • Stay calm and remain with the casualty
    • Note the start time and length of the seizure
    • Protect the head from impacts
    • Remove nearby objects and/or bystanders to protect from harm as cuts,
    abrasion, suffocation, burns, and broken bones or teethes…
    • Loosen tight clothing
    • Follow the casualty’s seizure management plan (if there is one in place)
    • When convulsions stop, or if vomiting starts, roll into recovery position and
    maintain airway
    • Observe and monitor breathing
    • Call for an ambulance
    • Reassure and let the person rest until fully recovered
    First aid management DO NOTs include:
    • Do not put anything in the casualty’s mouth
    • Do not restrain the casualty
    • Do not move the casualty unless they are in danger
