First Aid

o response to someone who is injured First aider – person who takes action while taking care to keep everyone involved safe

FIRST STEPS IN EMERGENCY

  1. Survey the scene
  2. Prevent cross infection
  3. Rescue
  4. Send for Medical Help

Assessing the sick or injured

  1. Determine if victim is conscious or unconscious
  2. Check ABC’s a. Airway b. Breathing c. Circulation of blood
  3. CPR (Cardiopulmonary Resuscitation)
  4. Control Bleeding
  5. Direct pressure a. Elevation b. Tourniquet
  6. Treat poisoning

 Breathing and Circulation

o supplies the body’s vital organs with enough oxygen and nutrients needed to operate o Poor blood circulation can potentially harm the heart, kidneys, and brain o numbness in the hands and feet

CPR

o Position hands on chest o Give 30 chest compressions o Open airway- begin breaths o Check for response o Open the airway

o Check breathing

Unresponsive casualty Priority: maintain open airway If you are untrained  Chest- compression-only CPR

Key Elements for Survival: o Emergency help o CPR o AED o Specialized Treatment

Life-Saving Priorities

Maintain circulation  If the heart stops beating, blood does not circulate in the body  Vital organs – brain becomes oxygen starved and cannot survive for more than 3-4 minute without a supply of oxygen

How do you maintain circulation?  Artificial chest compressions  Mechanical aid to the heart

Restoring Heart Rhythm  AED – automated external defibrillator  The earlier the AED is used, the greater the chance of suviving

An Open Airway o Lift the chin and tilt the head back – it lifts the tongue away from the air passage

Breathing for a Casualty o Exhaled air contains 16% oxygen (5% less than inhaled air) and small Carbon dioxide

 Shock

o critical condition brought on by the sudden drop in blood flow o trauma, heatstroke, blood loss, an allergic reaction, severe infection, poisoning, severe burns

Recognition o Cold skin o Sweating o Rapid pulse and breathing o Nausea or vomiting o Enlarged pupils o Fatigue o Dizziness o Anxiousness Bluish tinge to lips or fingernails

What to do: o Treat possible cause of shock o Help the casualty lie down o Call emergency hotline o Loosen tight clothing o Keep the casualty warm o Monitor and record vital signs

 Seizure

o Convulsion o Disturbance in the electrical activity of the brain o Person becomes unresponsive or response is impaired o Common cause: epilepsy

What to do: o Make space around casualty o Protect the casualty’s head o When the convulsive movements have ceased o Monitor and record vital signs

 Burn

Depths of Burns

First-degree (superficial) burns o Involves only the outermost layer of skin: epidermis o Heals well if first aid is given promptly and blisters don’t form o Ex. Sunburn Second-degree (partial thickness) burns o Very painful o Destroy the epidermis and cause skin to become red and blistered Third-degree (full thickness) burns o Pain sensation is lost – mask the severity of the injury o Skin is waxy, pale or charred o Burns that need Hospital Treatment

 All third-degree burns  All second-degree burns larger than 1% of the body surface  All first-degree burns larger than 5% of body  Burns: face, hands, feet or genital area  Burns of mixed pattern
