This guide is for general information only and doesn't replace hands-on, accredited first aid training. In a medical emergency, always call 999 (or 112) immediately.
A person can "collapse" for all sorts of reasons: fainting, a cardiac event, a seizure, or simply being unresponsive when you find them. Whatever the cause, the first few minutes matter, and the same simple sequence applies every time: check for danger, check their response, then check their airway and breathing.
Before you approach, make sure the area is safe for you, the casualty and anyone nearby. Don't put yourself at risk trying to reach someone in a dangerous situation, such as near traffic or a live electrical hazard.
Kneel beside them, gently shake their shoulders and ask loudly if they're okay. Someone who opens their eyes, speaks or moves is responsive. No reaction at all means they're unresponsive and need urgent help.
If there's severe bleeding, deal with that first, apply direct pressure to the wound before you move on to airway and breathing, and get someone to call 999.
Place one hand on their forehead to gently tilt the head back, and use two fingers under the chin to lift it. This moves the tongue away from the back of the throat and helps clear the airway.
With the airway still open, look, listen and feel for normal breathing for up to 10 seconds: watch the chest for movement, listen for breath sounds, and feel for breath on your cheek.
Watch out for agonal gasping, slow, noisy gasps with the mouth open. This is not normal breathing, it's a sign of cardiac arrest, and means you should start CPR immediately.
If they're unresponsive but breathing normally, place them in the recovery position and call 999 if it hasn't already been done:
If they're unresponsive and not breathing normally, call 999 immediately (or get someone else to, and to find a defibrillator if one's nearby) and start CPR without delay. This is a hands-on skill that's genuinely best learned in person, our Basic Life Support course covers CPR, AED use and the recovery position from scratch, with no prior experience needed.
Call 999 (or 112) straight away if the person is unresponsive, whether or not they're breathing normally. Don't wait to see if they improve.
Reading the steps is a good start, but confidence with a collapsed casualty comes from practising it. Our Basic Life Support and EFAW courses cover this scenario in full, with real manikins.
