Cardiac arrest — when the heart suddenly stops beating — can happen to anyone, anywhere. It can happen to a stranger at a shopping mall, a coworker at their desk, or someone you love at home.
When it happens, every second matters. For every minute that passes without CPR, the chance of survival drops by about 10%. That means bystanders — ordinary people like you — play an enormous role in whether someone lives or dies.
Around 70% of out-of-hospital cardiac arrests happen at home. The person who responds first is almost always a family member or bystander — not a paramedic.
How Do You Know Someone Needs CPR?
- ❓They are unresponsive — they don't react when you tap their shoulder and loudly ask "Are you okay?"
- 💨They are not breathing normally — no breath, or only occasional gasping (agonal breathing), which is not the same as normal breathing
- 💔They have no pulse — though checking for a pulse is difficult for non-professionals; focus on unresponsiveness and abnormal breathing
If someone is unresponsive and not breathing normally, assume they need CPR and call 911 immediately — or shout for someone nearby to call while you begin.
Hands-Only CPR: The Simple Version
Don't know how to do "full" CPR with rescue breaths? That's okay. Hands-only CPR is recommended by the American Red Cross for untrained bystanders — and it's nearly as effective.
Call 911 first (or shout for someone else to)
Tell the dispatcher someone is unresponsive and not breathing. They will guide you through everything.
Position your hands
Kneel beside the person. Place the heel of one hand on the center of their chest (on the breastbone). Place your other hand on top and interlace your fingers.
Push hard and fast
With arms straight, push down at least 2 inches. Release fully, then push again. Aim for 100–120 pushes per minute — about the tempo of "Stayin' Alive" by the Bee Gees.
Keep going until help arrives
Don't stop unless the person starts breathing normally, an AED becomes available, or a trained responder takes over. CPR is exhausting — if others are present, swap every 2 minutes.
🎵 The right rhythm is 100–120 compressions per minute

What About Rescue Breaths?
If you've been trained in CPR with rescue breaths, use the 30:2 method — 30 chest compressions followed by 2 breaths. Tilt the head back gently, lift the chin, pinch the nose, and breathe into their mouth until you see the chest rise.
If you're untrained, unsure, or uncomfortable with rescue breaths, skip them entirely. Hands-only CPR is effective and far better than doing nothing.
You Won't Make It Worse
Many bystanders hesitate because they're afraid of doing something wrong. Here's the truth: if someone's heart has stopped, CPR cannot make things worse. The only way to hurt your chances of saving them is to do nothing.
Good Samaritan laws in every US state protect bystanders who attempt CPR in good faith. You are legally protected when you try to help.
💡 Take a Class
A certified CPR class takes about 2 hours and is offered by the American Red Cross (and equivalents like the American Heart Association). Hands-on practice builds the confidence to actually act when it counts.
