Let’s embark on this vital learning journey, where you will gain the skills to make critical differences in emergency scenarios. Welcome to Lesson 3: First Aid for an Unresponsive Casualty.

In this part of Lesson 3, we focus on the initial steps of providing first aid to an unresponsive casualty. This involves identifying unresponsiveness and taking appropriate immediate actions.

Identifying an Unresponsive Casualty

  • Objective: Determine whether a casualty is unresponsive.
  • Actions: Approach the casualty safely. Check for responsiveness by gently shaking their shoulders and asking loudly, “Are you okay?” Look for any signs of movement, listen for any sounds, and observe if they open their eyes.
  • Example:
    • Scenario in a Park: You find a person lying on the ground. You approach safely and check for responsiveness as described. The person doesn’t respond to your voice or touch, indicating they are unresponsive.

Immediate Actions for an Unresponsive Casualty

Once you have established that a casualty is unresponsive, your immediate actions are critical. Here are the steps you should take:

  1. Call for Help: If you’re alone, shout for help nearby. Do not leave the casualty unless absolutely necessary.
  2. Open the Airway: Tilt the head back and lift the chin to open the airway. This simple action can be lifesaving, especially if the casualty’s breathing is compromised.
  3. Check for Breathing: Place your ear near the casualty’s mouth and nose. Look for chest movements, listen for breathing sounds, and feel for breath on your cheek. Spend no more than 10 seconds on this.
  4. Call Emergency Services: If the casualty is not breathing or only gasping (agonal breathing), call for emergency services immediately. If possible, use a speakerphone to keep your hands free.
  5. Prepare to Perform CPR: If the person is not breathing normally, prepare to start CPR. Ensure the casualty is on a flat surface.
  6. Continuous Monitoring: If the casualty is breathing but still unresponsive, keep monitoring their breathing and response level until help arrives. Place them in the recovery position if there are no signs of injury, particularly to the spine.
  • Example:
    • Office Incident: A colleague collapses and is found to be unresponsive and not breathing normally. You call for help, open their airway, confirm the absence of normal breathing, and then call 911. You begin CPR immediately, following the correct technique until emergency services arrive.

Importance of Timely Response

The initial moments after identifying an unresponsive casualty are crucial. Quick and correct actions can significantly increase the chances of survival, particularly in cases of cardiac arrest. Understanding and practicing these steps ensures you are prepared to handle such emergencies effectively.

In the second part of Lesson 3, we delve into the specifics of performing Cardiopulmonary Resuscitation (CPR) and using an Automated External Defibrillator (AED), both crucial in the management of unresponsive casualties who are not breathing normally.

Cardiopulmonary Resuscitation (CPR)

  • Objective: Perform CPR to maintain circulation and breathing in a casualty who is not breathing normally.
  • Actions:
    1. Position Your Hands: Place the heel of one hand in the center of the casualty’s chest. Place your other hand on top and interlock your fingers.
    2. Administer Chest Compressions: Keep your arms straight and press down hard and fast, compressing the chest by at least 2 inches. Aim for a rate of 100-120 compressions per minute.
    3. Provide Rescue Breaths (if trained): After 30 compressions, give 2 rescue breaths by tilting the head back, lifting the chin, pinching the nose, and breathing into the mouth.
  • Example:
    • Home Scenario: A family member is found unresponsive and not breathing. After calling for emergency services, you start CPR, performing chest compressions and rescue breaths as trained.

Using an Automated External Defibrillator (AED)

  • Objective: Use an AED as soon as it is available to increase the chances of survival in cases of cardiac arrest.
  • Actions:
    1. Turn on the AED: Follow the spoken/visual instructions.
    2. Attach the Pads: Expose the casualty’s chest and attach the AED pads as indicated.
    3. Ensure Everyone is Safe: Make sure no one is touching the casualty when the AED analyzes the heart rhythm and before delivering a shock.
    4. Deliver the Shock: If advised by the AED, press the shock button. Immediately resume CPR after the shock is delivered, until the AED reanalyzes or emergency services take over.
  • Example:
    • Public Place Incident: You locate an AED in a shopping mall where a person has collapsed and is unresponsive. You attach the AED pads as instructed and follow the prompts to deliver a shock. CPR is continued as advised by the AED.

Managing Special Cases

  • Agonal Breathing: Recognize and understand that gasping or irregular breathing may occur in cardiac arrest. It should not be mistaken for normal breathing.
  • CPR for Children and Infants: Learn the modifications for performing CPR on children and infants, such as using only one hand or two fingers for chest compressions and giving gentle rescue breaths.

Importance of Early Intervention

The chance of survival decreases with each minute that passes without CPR and defibrillation. Early intervention with CPR and the use of an AED significantly increases the chances of survival and recovery for a casualty in cardiac arrest.

In the third part of Lesson 3, we’ll focus on managing special cases that often arise with unresponsive casualties, including recognizing and responding to different types of unresponsiveness and handling complications that can occur during resuscitation efforts.

Recognizing Different Types of Unresponsiveness

  • Objective: Differentiate between various causes of unresponsiveness and apply appropriate first aid techniques.
  • Types of Unresponsiveness:
    1. Fainting or Syncope: Often a temporary loss of consciousness due to a drop in blood pressure. The casualty usually recovers quickly.
    2. Seizure: Uncontrolled electrical activity in the brain can cause convulsions. After a seizure, a person may be unresponsive for a short period.
    3. Drug or Alcohol Overdose: Can lead to reduced responsiveness or unconsciousness. Be cautious as their breathing could be compromised.
    4. Stroke or Brain Injury: May cause varying levels of consciousness. Look for other signs like facial drooping or weakness on one side of the body.
  • Example:
    • Workplace Scenario: A colleague collapses and is initially unresponsive. Upon checking, they are breathing normally but are confused and disoriented, suggesting a possible fainting episode rather than cardiac arrest.

Handling Complications During Resuscitation

  • Objective: Address and manage potential complications that can arise while performing CPR or using an AED.
  • Common Complications:
    1. Vomiting: If the casualty vomits, roll them onto their side to clear the airway, then continue with CPR.
    2. Fractured Ribs: Aggressive chest compressions may cause rib fractures. While distressing, it’s important to continue CPR as the benefit outweighs the risk.
    3. Changing Rescuers: If another trained responder is available, swap every 2 minutes to maintain effective compressions.
  • Example:
    • Community Event Incident: During CPR, the casualty vomits. You quickly clear the airway by turning them on their side, then resume chest compressions, ensuring effective CPR is continued.

Post-Resuscitation Care

  • Objective: Provide appropriate care after the casualty regains consciousness or until emergency services take over.
  • Actions: If the casualty starts breathing normally, place them in the recovery position, monitor their condition, and provide comfort and reassurance.
  • Example:
    • Home Emergency: After several minutes of CPR, the casualty starts breathing and regains consciousness. You place them in the recovery position, reassure them, and continue to monitor their condition until emergency services arrive.

Emotional Support and Self-Care

  • Objective: Understand the emotional impact of providing emergency first aid and the importance of self-care.
  • Considerations:
    1. Emotional Impact: Providing first aid, especially CPR, can be emotionally taxing. Acknowledge your feelings and seek support if needed.
    2. Debriefing: After a resuscitation attempt, it’s beneficial to debrief with medical professionals or a support team to process the experience.
  • Example:
    • Aftermath of an Emergency: Following a stressful CPR situation, you talk to a counselor to discuss your feelings and experiences, helping to manage any emotional aftermath.
