Every second counts in an emergency. When someone’s heart stops beating or they stop breathing, immediate action can mean the difference between life and death. That’s where CPR (Cardiopulmonary Resuscitation) comes in.

What Is CPR?

CPR is a lifesaving technique that combines chest compressions and rescue breaths to keep blood and oxygen circulating in the body until professional medical help arrives. Even if you’ve never used it, just knowing the basics can prepare you to act confidently in a crisis.

CPR Basics

Here are the core steps recommended by major health organizations like the American Heart Association (AHA):

  1. Check responsiveness and call for help – Tap the person and shout to see if they respond. If not, call 911 (or ask someone else to).
  2. Start chest compressions – Place the heel of one hand in the center of the chest, put your other hand on top, and push hard and fast (about 100–120 compressions per minute, roughly to the beat of “Stayin’ Alive”).
  3. Give rescue breaths (if trained) – After 30 compressions, tilt the head back, lift the chin, and give 2 breaths. If you’re not trained in rescue breathing, “Hands-Only CPR” (just compressions) is still highly effective.
  4. Use an AED if available – Automated External Defibrillators (AEDs) are often found in public places. They give simple, step-by-step instructions and can deliver a life-saving shock.

Continue until emergency responders arrive or the person starts breathing again.

Why CPR Training Matters

Reading about CPR is a start, but practicing the technique is what builds confidence. Proper training helps you:

  • Learn the correct hand placement and depth for compressions.
  • Practice timing to maintain the right rhythm.
  • Get comfortable using an AED.
  • Understand how to adapt CPR for infants and children.

How to Get Certified

There are several ways to receive official CPR training and certification:

  • American Heart Association (AHA): Offers in-person and blended online courses for individuals and groups.
  • American Red Cross: Provides CPR, AED, and First Aid courses across the country.
  • Local hospitals and community centers: Many run affordable training sessions.
  • Online courses (with in-person skills checks): Convenient for busy schedules.

Most certifications are valid for two years and can be renewed with a refresher course.

Final Thoughts

CPR is a skill you hope you never need to use — but one that can save a life when it matters most. Taking a few hours to get trained and certified equips you with the confidence to step in during an emergency. If you haven’t yet, look up a local CPR class near you. The knowledge you gain could make you the reason someone gets a second chance at life.
