Chest Pain vs Cardiac Arrest: When to Start CPR

Does Chest Pain Mean CPR Is Needed?

No. Chest pain alone is not a reason to start CPR. A person with chest pain may be having a heart attack, but they may still be awake and breathing. Their heart can continue beating even when a blood vessel supplying the heart is blocked.

CPR should only begin when someone is unconscious, does not respond, is not breathing normally, or has collapsed and shows signs of cardiac arrest. Starting CPR on someone who is conscious and breathing normally can cause unnecessary pain and injuries.

Quick Guide: When Should You Start CPR?

Here's how to react in four common situations:

• Chest pain, but awake and breathing — do not start CPR: Call emergency services, help the person sit comfortably, keep them calm, and monitor their condition.

• Sudden collapse, no response, abnormal breathing — start CPR immediately: Call emergency services, ask someone to bring an AED if available, and begin chest compressions.

• Unconscious, occasional gasping sounds — start CPR immediately: Gasping is not normal breathing and can be a sign of cardiac arrest.

• Unconscious but breathing normally — do not start CPR: Call emergency services, place the person in a safe recovery position, and continue monitoring them.

What Is the Difference Between a Heart Attack and Cardiac Arrest?

A heart attack and cardiac arrest are serious conditions, but they are not the same.

• Heart attack: a blood flow problem: Happens when a blood vessel supplying the heart becomes blocked. The heart usually keeps beating, but part of the heart muscle may not receive enough oxygen. Common warning signs include chest pressure or heaviness, pain spreading to the arm, neck, jaw, back, or stomach, shortness of breath, cold sweating, nausea, dizziness, and sudden unusual tiredness. A person having a heart attack may still be conscious and able to speak.

• Cardiac arrest: a heart pumping emergency: Happens when the heart suddenly stops pumping blood effectively. The person usually collapses without warning, becomes unconscious, does not respond, and stops breathing normally or only makes gasping sounds. Cardiac arrest requires immediate action — CPR helps keep blood flowing to the brain and vital organs until emergency teams arrive.

When Should You Call Emergency Services for Chest Pain?

Chest pain can be a warning sign of a heart attack, particularly when it feels like strong pressure or squeezing, a heavy weight on the chest, or burning discomfort that spreads to the arm, jaw, back, or neck. Chest pain can also come from other causes, such as muscle injuries, digestive problems, stress or anxiety, or lung conditions — but because serious heart problems can sometimes begin with mild symptoms, new or unexplained chest pain should always be checked by a healthcare professional.

Call emergency services if chest pain starts suddenly, feels like pressure, squeezing, or heaviness, spreads to the arm, jaw, back, or neck, or comes with sweating, shortness of breath, dizziness, or nausea. Do not wait to see if the pain disappears — early medical care can make an important difference, especially during a possible heart attack.

What Should You Do When Someone Has Chest Pain?

If the person is awake and experiencing chest pain, follow these steps:

• Call emergency services: Don't take a "wait and see" approach — emergency teams can provide care quickly and help prevent complications.

• Keep the person resting: Help them sit in a comfortable position, avoid walking or physical effort, and stay calm.

• Follow medical instructions about medication: Emergency responders may recommend aspirin for some adults if it's safe for them. If the person has their own prescribed heart medication, help them take it as directed — never give medication prescribed for someone else.

• Watch for changes: Stay with the person and monitor their condition. If they collapse, become unconscious, or stop breathing normally, the situation has changed and CPR may be needed.

How to Perform Hands-Only CPR

For most adults and teenagers experiencing cardiac arrest, Hands-Only CPR is recommended for people without medical training.

• Call for help: Call emergency services immediately and ask someone nearby to bring an AED if available.

• Push hard and fast: Place the heel of one hand in the center of the chest, your other hand on top, and push hard and fast — aim for 100 to 120 compressions per minute, allowing the chest to rise fully between pushes. Continue until emergency responders arrive or an AED is ready. A useful rhythm to remember is the beat of the song "Stayin' Alive."

How Does an AED Help During Cardiac Arrest?

An AED (automated external defibrillator) is a machine that checks the heart rhythm and can deliver a shock if needed. AEDs are designed so that even non-medical users can operate them during an emergency.

If an AED is available:

• Turn it on and follow instructions: Turn on the device and follow its voice instructions, then attach the pads to the person's chest.

• Let the AED check the rhythm: Do not touch the person while the machine checks the heart rhythm, and give a shock only if the AED tells you to.
