NOLS Wilderness Medicine (7th Edition)
The field text used in NOLS and Wilderness Medicine Institute courses, covering patient assessment, shock, soft-tissue and orthopaedic injury, and environmental emergencies. Teaches the judgement needed when evacuation is hours away, including when resuscitation is and is not indicated.
St John Ambulance First Aid Advice
Condition-by-condition first aid reference maintained by St John Ambulance's clinical team, covering adult, child and infant CPR, choking, severe bleeding, shock and roughly a hundred other emergencies. Each entry gives recognition signs and a stepwise treatment sequence.
STOP THE BLEED Interactive Course
The American College of Surgeons' free interactive course on life-threatening haemorrhage, derived from military combat casualty care. Covers direct pressure, wound packing and tourniquet application through video demonstration and quizzes. Physical tourniquet practice still requires the in-person class.
Lifesaver — Interactive CPR and Emergency Decision Trainer
A free browser-based interactive film from Resuscitation Council UK in which four filmed emergencies force real-time decisions about calling for help, compressions, defibrillation, choking and the recovery position. Builds recognition speed under pressure; manikin practice is still required for the physical skill.
ILCOR Consensus on Science with Treatment Recommendations (CoSTR)
The evidence layer beneath every national CPR guideline: ILCOR's systematic and scoping reviews with graded treatment recommendations, published continuously and open for public comment. Shows why each recommendation exists and how strong the underlying trial evidence actually is. It answers the question guidelines cannot: why is compression depth 5–6 cm, why did the choking sequence change, how weak is the evidence for any given first aid intervention. A learner who reads CoSTR stops treating resuscitation protocol as arbitrary ritual and starts seeing it as a graded evidence hierarchy.
Resuscitation Council UK — 2025 Resuscitation Guidelines
Full free text of the 2025 UK resuscitation guidelines, running from lay-rescuer basic life support through advanced life support, paediatrics, a new first aid section, and ethics. Gives exact compression depth and rate, AED handling, and the revised call-first sequence.
