Learn to Save a Life

What Is CPR?

CPR (cardiopulmonary resuscitation) is an emergency procedure that can save lives when someone's heart stops beating. When cardiac arrest occurs, the heart can't pump blood to the brain and organs. CPR manually pumps blood through the body, keeping vital organs alive until medical help arrives. Immediate CPR can double or triple survival rates. You don't need medical training to learn basic CPR—hands-only CPR can be learned in minutes and performed by anyone.

Most cardiac arrests happen at home. Learning CPR means you could save someone you love.

When CPR Is Needed

Person is unresponsive

Not breathing or only gasping

No pulse felt (if trained to check)

Cardiac arrest vs heart attack

Immediate action is critical

Brain damage begins in 4-6 minutes

Every minute without CPR reduces survival

Any CPR is better than no CPR

CPR Approaches

Hands-Only CPR

Chest compressions only

✓ For untrained bystanders or teens/adults. Push hard and fast in the center of the chest. Recommended by the American Heart Association for sudden cardiac arrest.

Traditional CPR

Compressions and rescue breaths

✓ 30 compressions then 2 breaths. For trained responders, drowning victims, or children. Provides oxygenation along with circulation.

Child CPR

Modified for children

✓ Similar technique but gentler. Use one hand for small children. Compressions to breaths ratio may differ. Children's needs differ from adults.

Infant CPR

Special technique for babies

✓ Use two fingers for compressions. Cover nose and mouth for breaths. Different technique due to small size and fragility.

Hands-Only CPR Steps

Check the Person

Tap shoulders and shout 'Are you okay?' Check for breathing. Look for chest rise. If unresponsive and not breathing normally, start CPR.

Call 911

Call immediately or have someone else call. If you're alone, call 911 first, then start CPR. If others are present, one calls while one starts CPR.

Position Your Hands

Place the heel of one hand in the center of the chest (on the lower half of the breastbone). Place your other hand on top and interlock fingers.

Position Your Body

Position yourself so your shoulders are directly over your hands. Keep your arms straight. You'll use your upper body weight for compressions.

Push Hard

Push down at least 2 inches (5 cm) into the chest. Use your body weight. Don't worry about hurting them—their life is at stake.

Push Fast

Compress at a rate of 100-120 times per minute. Think of the beat to 'Stayin' Alive' by the Bee Gees. Don't stop.

Allow Full Recoil

Let the chest come back up completely after each compression. Don't lean on the chest between compressions. Full recoil helps blood flow.

Keep Going

Continue until EMS arrives, an AED is available, the person starts breathing, or you're too exhausted to continue. Don't stop early.

Frequently Asked Questions

Will I hurt someone by doing CPR?

You might cause broken ribs or bruising, but these injuries are treatable. Not doing CPR when needed results in death. Better to have broken ribs than to be dead.

What if I do CPR wrong?

Any CPR is better than no CPR. Even imperfect CPR helps. Push hard and fast in the center of the chest—you can't really mess up hands-only CPR.

Do I need to give rescue breaths?

Not necessarily. Hands-only CPR (compressions only) is recommended for untrained people helping teens or adults. It's simpler and just as effective in most cases.

How fast should I do compressions?

100-120 compressions per minute. Think of the beat to 'Stayin' Alive,' 'Crazy in Love,' or 'Hips Don't Lie.' It's a fast, steady rhythm.

When should I stop CPR?

Stop when: EMS arrives and takes over, an AED is available, you see clear signs of life (normal breathing and movement), or you're too exhausted to continue.

What if there's an AED available?

Use it! AEDs (automated external defibrillators) are designed for anyone to use. Turn it on and follow voice prompts. They can restart a heart.

Is CPR different for children?

Slightly. For children 1-puberty, use one hand if small. The ratio may be 30:2 (compressions to breaths) if trained. Learn child-specific techniques.

What if the person vomits during CPR?

Turn their head to the side to clear the mouth, then reposition and continue CPR. Don't stop for more than a few seconds.

Should I be afraid of lawsuits?

No. Good Samaritan laws protect people who act in good faith to help in emergencies. You're legally protected when you try to help.

Where can I get CPR certified?

Red Cross, American Heart Association, many hospitals, community centers, and online courses offer certification. In-person training gives hands-on practice. Certification is valid for 2 years.
