CPR Myths

When it comes to life-saving skills like CPR (Cardiopulmonary Resuscitation), misinformation can be more dangerous than doing nothing at all. TV shows, movies, and outdated advice have shaped how many people think CPR works—and unfortunately, a lot of that information is just plain wrong.

In an emergency, believing a myth could cost someone their life. Let’s set the record straight and bust some of the most common CPR myths, so you’re ready to act with skill and confidence when it really matters.

Myth #1: “CPR Will Always Restart the Heart”

Reality: CPR doesn’t restart the heart—it keeps blood and oxygen flowing until professional help arrives.

TV dramas often show someone waking up after a few chest compressions. In reality, CPR’s main purpose is to maintain circulation and oxygen delivery to the brain and vital organs during cardiac arrest. It buys time—but only a defibrillator (AED) or medical intervention can restore a normal heartbeat.

Myth #2: “If You Do CPR Wrong, You’ll Hurt the Person”

Reality: If someone is in cardiac arrest, they’re already clinically dead. Doing something—even imperfectly—is better than nothing.

It’s true that CPR can cause broken ribs or bruising, but that’s not what kills people—lack of oxygen does. If someone isn’t breathing and has no pulse, don’t hesitate. Your actions may give them the only chance at survival.

Myth #3: “You Can Tell if Someone Needs CPR Just by Looking”

Reality: People in cardiac arrest often look like they’re gasping or snoring—but they’re not breathing effectively.

This is called agonal breathing, and it can be misleading. If someone is unresponsive and not breathing normally, start CPR. Time is critical—every minute without CPR reduces survival chances by 7–10%.

Myth #4: “Children and Infants Need the Same CPR as Adults”

Reality: The technique for CPR varies by age.

• Infants (under 1 year): Use two fingers for compressions.

• Children (1–8 years): Use one or two hands depending on size.

Taking a certified course will teach you how to safely and effectively perform CPR on all age groups.

Myth #5: “Only Medical Professionals Should Perform CPR”

Reality: Bystanders save lives. Most cardiac arrests happen at home—not in hospitals.

The first person on the scene is rarely a doctor or EMT. It’s more likely a spouse, parent, coworker, or stranger. CPR training is for everyone, not just healthcare workers.

Even a basic course can equip you with the skills to act confidently and correctly in a crisis.

Myth #6: “Calling 911 Is Enough”

Reality: Emergency responders may take several minutes to arrive. CPR needs to be started immediately to be effective.

Brain damage can begin within 4 to 6 minutes of cardiac arrest. Waiting for help without doing anything drastically lowers survival chances. By starting CPR right away, you bridge the gap between collapse and medical intervention.

CPR Facts:

• Every year, over 350,000 out-of-hospital cardiac arrests occur in the U.S.

• Bystander CPR can double or triple survival chances.

• Most people who survive were helped by someone nearby—not by emergency services alone.

Conclusion 

Don’t let fear, myths, or uncertainty stop you from helping. CPR isn’t about perfection—it’s about action. The more we dispel the myths, the more lives we can save.
