Elementary First Aid (STCW EFA) - Core Facts and Decision Rules

  • Primary survey order: Danger, Response, Airway, Breathing, Circulation (DRABC); correct any immediately life-threatening problem before moving to the next step.

  • Adult rescue breathing rate is about 10-12 breaths per minute (one breath every 5-6 seconds); each insufflation lasts about 1 second and should just make the chest rise.

  • Adult CPR: compressions at 100-120 per minute, depth 5-6 cm, ratio 30 compressions to 2 ventilations; switch rescuer about every 2 minutes to limit fatigue.

  • Recovery position is indicated for an unresponsive casualty who is breathing normally and has no suspected spinal injury; it keeps the airway clear and allows vomit to drain.

  • Severe external bleeding: apply firm direct pressure with a dressing, add layers without removing soaked dressings, and elevate the limb if no fracture is suspected.

  • Burns: cool with clean running water for at least 10-20 minutes, remove rings and tight items before swelling, and never burst blisters or apply oils, butter or ice.

  • Suspected spinal injury after a fall or collision: keep the head aligned with the spine, do not move the casualty unless there is immediate danger, and immobilise before transport.

  • Shock signs include pale clammy skin, rapid weak pulse, rapid shallow breathing, thirst and restlessness; keep the casualty lying down, warm and reassured, and give nothing by mouth.

Elementary First Aid (STCW EFA) - Assessment, Choking, Drowning and Casualty Handling

  • Unconsciousness check: if no normal breathing within 10 seconds, treat as cardiac arrest and start CPR; occasional gasps are not normal breathing.

  • Adult choking (conscious): give up to 5 back blows between the shoulder blades; if ineffective, give up to 5 abdominal thrusts, alternating until the obstruction clears.

  • Drowning casualty: prioritise ventilation - give 2 initial rescue breaths before compressions, since the cause is usually hypoxia; remove from water only if safe to do so.

  • Recovery position is not used for a casualty who is not breathing, has a suspected spinal injury, or is a pregnant woman (place her on her left side instead).

  • Heat exhaustion signs are heavy sweating, cool pale skin, cramps and dizziness; move to shade, loosen clothing and give oral fluids if fully conscious.

  • Fracture immobilisation: support the limb in the position found, check circulation beyond the injury, and immobilise the joints above and below the break.

  • Handover to medical help uses SAMPLE history: Signs and symptoms, Allergies, Medications, Past history, Last meal, Events leading to the incident.

  • Infection control: wear disposable gloves, avoid contact with blood and body fluids, and wash hands or use alcohol gel after any first aid contact.

Elementary First Aid (STCW EFA) - Casualty Care on Board and Medical Support

  • First aider's role is to preserve life, prevent the condition worsening, and promote recovery - not to diagnose or prescribe medication.

  • Use the vessel's medical guide and radio medical advice (TMAS) for drug administration; the master or designated officer authorises treatment beyond basic first aid.

  • Record findings in the medical log: time of incident, casualty details, observations, treatment given and response, to support later medical advice.

  • Casualty with chest pain: sit them up, keep them calm and still, loosen tight clothing, and seek urgent medical advice; do not give food or drink.

  • Diabetic emergency: if conscious and able to swallow, give sugar (glucose gel, sweet drink); if unconscious, place in recovery position and never give anything by mouth.

  • Seizure care: protect the head, clear nearby hazards, do not restrain or put anything in the mouth, and place in the recovery position once the seizure ends.

  • Hypothermia: move to a warm dry place, remove wet clothing, wrap in blankets, and give warm sweet drinks only if fully conscious; rewarm gradually.

  • Eye injury from chemicals: irrigate with clean water or saline for at least 15 minutes, keeping the eyelid open, and arrange medical assessment as soon as possible.
