The American Heart Association has promoted Hands-Only CPR as a way to empower more bystanders to act during cardiac emergencies. The concept is simple: if you see a teen or adult suddenly collapse, call 911 and push hard and fast in the center of the chest.
Why Hands-Only?
Research shows that for adults who collapse from sudden cardiac arrest, Hands-Only CPR is as effective as conventional CPR with breaths in the first few minutes. More importantly, it removes the barrier that prevents many bystanders from acting — reluctance to perform mouth-to-mouth on a stranger.
The Two Steps
Step 1: Call 911 (or tell someone else to call).
Step 2: Push hard and fast in the center of the chest at a rate of 100-120 compressions per minute.
That's it. No rescue breaths. No complicated sequence. Just push.
When to Use It
Hands-Only CPR is recommended for untrained bystanders or trained rescuers who are not confident in giving breaths. It's most effective for witnessed sudden cardiac arrests in adults and teens.
When You Need Full CPR
Conventional CPR with breaths is still recommended for infants, children, drowning victims, drug overdoses, and any collapse believed to be caused by a breathing problem. In these cases, rescue breaths are critical because the victim's oxygen supply may already be depleted.
The Bottom Line
Any CPR is better than no CPR. If you're unsure, default to Hands-Only CPR. You cannot make things worse by trying. The victim is already in cardiac arrest — without intervention, they will die.
