Fact or Fiction: Can You Spot the CPR Myths?
Many people think they know CPR. But some of the most common beliefs about cardiac arrest, AEDs, and lifesaving intervention are simply wrong. Test your knowledge and see how many myths you can spot.
When someone suddenly collapses from cardiac arrest, every second matters.
Yet many people hesitate to act because they are afraid of doing something wrong. Others have heard information about CPR, AEDs, or cardiac arrest that simply isn't true. Unfortunately, these misconceptions can delay lifesaving care when it is needed most.
Whether you're a healthcare provider, teacher, coach, parent, or community member, understanding the facts can help you respond with confidence during an emergency.
Let's put your knowledge to the test.

Myth #1
Fact or Fiction?
CPR can restart the heart.
Answer: Fiction
This is one of the most common misconceptions about CPR.
CPR's primary purpose is not to restart the heart. Instead, high-quality chest compressions help circulate oxygen-rich blood to the brain and other vital organs until more advanced care can be provided.
Defibrillation with an AED, advanced life support interventions, and emergency medical care are often needed to restore a normal heart rhythm.
Think of CPR as buying time. It helps keep the body alive while additional lifesaving measures are put into place.

Myth #2
Fact or Fiction?
CPR is performed exactly the same way for adults and children.
Answer: Fiction
While the overall goal remains the same—maintaining circulation and oxygen delivery—there are important differences between adult and pediatric CPR.
Adults most commonly experience cardiac arrest due to a cardiac event. In children, respiratory emergencies are often a contributing factor. Because of this, rescue breaths play a particularly important role in pediatric resuscitation.
Compression depth, hand placement, compression techniques, and the use of AED pediatric pads may also differ depending on the child's age and size.
Understanding these differences is one reason why specialized training such as Pediatric Advanced Life Support (PALS) is so valuable for healthcare professionals who care for children.

Myth #3
Fact or Fiction?
You can hurt someone by using an AED.
Answer: Fiction
Many people are intimidated by Automated External Defibrillators (AEDs), but these devices are specifically designed to be used by ordinary people during extraordinary moments.
AEDs analyze the heart rhythm automatically and will only advise a shock if one is needed. If a shockable rhythm is not present, the device will not deliver a shock.
Modern AEDs provide clear voice prompts that guide rescuers through every step of the process.
You do not need to be a healthcare provider to use an AED. In fact, early defibrillation is one of the most important links in the Chain of Survival.

Myth #4
Fact or Fiction?
A heart attack and cardiac arrest are the same thing.
Answer: Fiction
Although the terms are often used interchangeably, they describe two very different medical emergencies.
A heart attack occurs when blood flow to part of the heart muscle becomes blocked.
Cardiac arrest occurs when the heart suddenly stops beating effectively due to an electrical malfunction.
A heart attack can sometimes lead to cardiac arrest, but not every heart attack results in cardiac arrest.
Recognizing the difference helps people understand why CPR and AED use are critical when someone experiences sudden cardiac arrest.

Myth #5
Fact or Fiction?
CPR always breaks ribs.
Answer: Fiction
Chest compressions must be performed with enough depth and force to effectively circulate blood. Because of this, rib injuries can occasionally occur, particularly in older adults.
However, CPR does not always result in broken ribs.
More importantly, the possibility of a rib injury should never prevent someone from providing CPR during cardiac arrest.
The alternative is far more serious.
A cracked rib can heal. A lack of blood flow to the brain and vital organs can be fatal within minutes.

Myth #6
Fact or Fiction?
Children can experience sudden cardiac arrest.
Answer: Fact
While sudden cardiac arrest is less common in children than adults, it absolutely can happen.
Potential causes include congenital heart disease, trauma, drowning, severe respiratory emergencies, genetic heart conditions, and other medical events.
This reality highlights the importance of CPR education in schools, youth sports organizations, childcare facilities, and communities.
Prompt recognition, CPR, and AED use can dramatically improve outcomes for pediatric patients experiencing cardiac arrest.

Myth #7
Fact or Fiction?
If someone is gasping occasionally, they don't need CPR.
Answer: Fiction
Agonal gasping is one of the most misunderstood signs of cardiac arrest.
These abnormal gasps may appear like breathing, causing bystanders to assume the person is still alive and breathing normally. In reality, agonal gasps are often an early sign of cardiac arrest.
If a person is unresponsive and only gasping or breathing abnormally, call 911, begin CPR, and retrieve an AED if one is available.
Recognizing this distinction can save valuable minutes during a cardiac emergency.

Myth #8
Fact or Fiction?
You must perform rescue breaths for CPR to be effective.
Answer: Fiction
For most adult bystanders witnessing a sudden cardiac arrest, Hands-Only CPR is recommended.
This means calling 911 and immediately beginning chest compressions.
Hands-Only CPR simplifies the process and encourages more people to take action during an emergency.
There are situations where rescue breaths remain important, including pediatric emergencies, drowning incidents, and situations involving trained healthcare providers.
The key takeaway is simple: if someone collapses from sudden cardiac arrest, don't wait. Start compressions.

Myth #9
Fact or Fiction?
You can be sued for helping during an emergency.
Answer: Fiction
Many people worry about legal consequences if they attempt to help someone during a medical emergency.
Fortunately, Good Samaritan laws exist to encourage bystanders to provide reasonable assistance in good faith.
While laws vary by state, these protections are designed to support people who step forward to help rather than stand by and do nothing.
Fear should never prevent someone from attempting to save a life.

Myth #10
Fact or Fiction?
The worst thing you can do during cardiac arrest is nothing.
Answer: Fact
This statement may be the most important lesson in this entire quiz.
Survival from sudden cardiac arrest depends on a series of actions known as the Chain of Survival:
Early recognition
Rapid activation of emergency services
Immediate CPR
Early defibrillation
Advanced medical care
Recovery support
Every minute without CPR decreases the likelihood of survival.
Taking action—even if you're nervous—is almost always better than doing nothing at all.
