First Aid and Emergency Care Guide

Here's a structured study guide for your first aid and emergency care class:

ABCs of Emergency Care

Airway, Breathing, Circulation (ABC):

• Airway: Ensure the airway is clear by using techniques such as head-tilt/chin-lift for unresponsive patients or jaw thrust for those with potential spinal injuries. Recognize that an obstructed airway can lead to brain damage or death within minutes. Common obstructions include the tongue, food, and foreign objects.

• Breathing: Check for breathing by looking for chest rise, listening for breath sounds, and feeling for air movement on the cheeks for ≤10 seconds. If absent, commence CPR immediately, providing rescue breaths as needed along with chest compressions. Ensure the rescuer is protected during this process by using barriers like a face shield if available.

• Circulation: Assess for pulse and monitor for severe bleeding. Control life-threatening bleeding through direct pressure, elevation, and if necessary, the application of a tourniquet. Recognize that circulation issues may also arise from shock, which can manifest as a weak pulse, rapid breathing, and clammy skin.Key Systems at Risk:

• Respiratory: Blocked airway, asthma attacks, choking incidents, or respiratory arrests due to overdose or illness.[2][6].

• Circulatory: Conditions such as cardiac arrest, severe bleeding, anaphylaxis, or shock can jeopardize circulation and require immediate response.[2][6].

• Nervous: Be alert for head trauma, stroke symptoms (e.g., facial drooping, weakness in limbs), and spinal cord injuries, which may compromise life functions.[2][10].

Care First vs. Call First

• Call First (Immediate 911): For scenarios involving unresponsive adults or teenagers, no breathing or gasping, and any instance of life-threatening bleeding, activate emergency services without delay.[6].

• Care First (1-2 minutes of care before calling): Critical for children and infants in emergencies unless the collapse was witnessed. Situations like drowning or respiratory emergencies also necessitate immediate care prior to calling for help.[6].

Consent in First Aid

• Explicit Consent: Always ask for permission by inquiring, "May I help you?" This is especially crucial for conscious adults to respect their autonomy.[3][19].

• Implied Consent: In situations where the individual is unresponsive, intoxicated, or a minor without a guardian, consent is assumed. This highlights the urgency of providing care in life-threatening situations.[3][27].

• Special Cases: In emergencies like choking, where verbal communication may not be possible, look for non-verbal cues such as nodding to signify consent to assist.[3].

Disease Transmission & Precautions

Universal Precautions:

• Treat all blood/body fluids as potentially infectious. Use personal protective equipment (PPE) such as gloves and masks, along with hand hygiene, to minimize the risk of transmission of diseases like HIV or Hepatitis. Avoid direct contact with any bodily fluids, and ensure handwashing immediately after care to eliminate contaminants.[4][20].

The 3 Cs of Emergency Response

1. Check:

   • Assess scene safety: Identify any hazards, control bystanders, and ensure there are no threats to your safety before assisting the victim.[1][11].

   • Evaluate the victim’s responsiveness and breathing conditions before proceeding.

2. Call: Activate Emergency Medical Services (EMS) (dial 911) for any life-threatening conditions such as severe bleeding or loss of consciousness.[1][6].

3. Care: Provide necessary care such as CPR, controlling bleeding, or stabilization until emergency personnel arrive.[1][11].

Incident Stress Management

• Stress First Aid (SFA): This approach prioritizes Cover (ensuring safety), Calm (providing reassurance to those affected), and Connect (offering support). Encourage individuals to express their feelings and concerns during traumatic experiences.

• Recognize signs: Be vigilant for symptoms such as hypervigilance, withdrawal from social interactions, or increased levels of irritability. It is essential to provide resources like access to counseling services and peer support groups to help individuals cope with emotional stress effectively.

Calling 9-1-1: Critical Information

When calling 911, ensure to provide:

• Location: Specify the exact address and any recognizable landmarks to facilitate a swift response.

• Victim’s Condition: Describe whether the victim is responsive, breathing, and any evident injuries.

• SAMPLE History:

  • Symptoms: Outline visible or reported symptoms from the victim

  • Allergies: Inform of any known allergies, especially to medications

  • Medications: List current medications that the victim is taking

  • Past Medical History: Mention any chronic conditions like diabetes or heart disease

  • Last Meal: Record the last time the victim consumed food or drink

  • Events Leading to Injury: Provide context on what occurred before the emergency situation arose. This information is crucial for emergency responders.[9][25].

Lay Responder Roles

• Quickly assess the scene and the victim's condition.

• Provide CPR/AED if needed, and control bleeding through methodical pressure application.

• Relay SAMPLE history to EMS responders when they arrive on the scene, ensuring accurate and timely information is available for treatment.

Moving Victims

Do NOT Move Unless:

• Immediate danger such as fire, flooding, or any hazardous situation that could lead to further injury.

• Moving is needed to perform lifesaving care, like if CPR cannot be administered due to the victim's position.Safe Techniques:

• Clothing Drag: Grasp the clothing near the shoulders to pull a victim to safety. Ensure you support their head and neck during the move, especially if spinal injury is suspected.

• Extremity Drag: If possible, pull by the ankles or wrists while carefully supporting their head to prevent more injury.[8][24].

Unresponsive Assessment

1. Check Responsiveness: Shout and gently tap the victim's shoulder while calling their name to check for any reaction.[6].

2. Scan for Breathing/Life-Threats: Check for breathing and any immediate life-threatening conditions within ≤10 seconds. Be aware of potential injuries that may not be visible by just looking.[6].

3. Activate EMS: If the victim is unresponsive and not breathing, call EMS (911) immediately to get professional help on the way.[6].

Life-Threatening Conditions

• ABCD Threats: Know that life-threatening conditions may involve:

  • Airway Obstruction: Recognize signs and act quickly, as this is critical for survival.

  • Breathing Failure: Immediate intervention is required to restore adequate oxygenation.

  • Circulation Loss: This may manifest as severe bleeding or loss of pulse, which requires rapid response.

  • Disability: Assess for signs of head or spine injuries that may impair function; early recognition is vital to minimize potential damage.[26].
