Would you know what to do in the moment when someone collapses right in front of you? Most people freeze. Their heart is racing, their mind goes blank, and precious seconds slip away. Yet when someone collapses, what you do in the first minute matters more than almost anything else that happens afterward.
This guide walks through the 8 steps to take when someone collapses, so you can act with confidence instead of panic.

In this article:
- Check the Scene for Danger
- Check for Responsiveness
- Call 911 Immediately
- Check for Breathing
- Start Hands-Only CPR
- Send Someone for an AED
- Use Recovery Position if Breathing
- Stay With Them Until Help Arrives
1. Check the Scene for Danger
Before you do anything else when someone collapses, look around. Is there traffic, fire, exposed wiring, or a crowd that could hurt you too? You can’t help anyone if you become the second victim. A quick scan takes only a couple of seconds and keeps both of you safer.
2. Check for Responsiveness
Once the scene is safe, kneel beside the person and tap their shoulders firmly. Ask loudly, “Are you okay?” No eye movement, no sound, no reaction — treat this as a medical emergency. The Red Cross’s guide to unresponsive patients outlines this same check as the first real branching point in an emergency response.
3. Call 911 Immediately
If someone collapses and doesn’t respond, call 911 right away, or point directly at one bystander and say, “You — call 911 now.” A specific instruction cuts through the confusion that keeps people from acting. Put your phone on speaker so the dispatcher can guide you through the next steps.
4. Check for Breathing
Look at the chest for about 10 seconds. Is it rising and falling normally? Gasping, irregular breaths, or no movement at all are red flags. This is one of the most important checks when someone collapses, since it determines whether you move to CPR or the recovery position.
5. Start Hands-Only CPR
If the person isn’t breathing normally, begin hands-only CPR immediately. Push hard and fast in the center of the chest, about 2 inches deep, at 100–120 compressions per minute. You don’t need formal training to start the 911 dispatcher can talk you through it, though CHF’s CPR training program is built to make this reflex second nature long before you ever need it.
6. Send Someone for an AED
While CPR is underway, send another bystander to find an Automated External Defibrillator, usually in a bright red or yellow case in schools, gyms, offices, and airports. The American Heart Association notes that pairing CPR with early AED use dramatically improves survival odds. Don’t stop compressions to search for it yourself delegate that task.
7. Use the Recovery Position if They’re Breathing
If the person is breathing normally but still unresponsive, gently roll them onto their side into the recovery position, top knee bent forward for stability. This keeps the airway clear and lowers the risk of choking.
8. Stay With Them Until Help Arrives
Don’t leave the person’s side. Keep talking to them calmly, note the time the collapse happened, and be ready to tell paramedics exactly what you saw. That information helps responders act faster the moment they arrive.
Why Knowing These Steps Matters
Someone can collapse from a heart attack, cardiac arrest, stroke, seizure, low blood sugar, or simple fainting — you won’t always know which one you’re facing. That’s exactly why these 8 steps work regardless of cause: check safety, responsiveness, and breathing first, then act on what you find. According to the American Heart Association, immediate bystander CPR can double or triple a person’s chance of survival, which is exactly why knowing what to do the moment someone collapses matters so much.
Build This Skill Before You Need It
Reading these steps is a good start, but muscle memory saves lives. CHF’s CPR training program and First Aid Education for Youth course walk participants through hands-on practice for exactly this scenario.
