What is cpr

Last updated: April 1, 2026

Quick Answer: CPR (Cardiopulmonary Resuscitation) is an emergency medical procedure that combines chest compressions and rescue breathing to restore blood circulation and oxygen delivery in someone experiencing cardiac arrest or stopped breathing.

Key Facts

Understanding CPR

Cardiopulmonary Resuscitation (CPR) is a life-saving emergency procedure designed to maintain blood circulation and oxygen delivery when someone's heart has stopped beating or they have stopped breathing. CPR combines manual chest compressions with rescue breathing to artificially pump blood through the body and deliver oxygen to vital organs. This procedure is critical for improving survival chances in cardiac emergencies, as brain damage can occur within minutes of oxygen deprivation. Prompt, effective CPR can double or triple survival rates in cardiac arrest cases.

CPR Technique and Procedure

Modern CPR typically involves the following steps:

When CPR is Needed

CPR is indicated in cardiac emergencies including sudden cardiac arrest, heart attack with loss of consciousness, severe choking, drowning, electrocution, and trauma with stopped breathing. The procedure should be initiated as quickly as possible, as every minute without CPR decreases survival chances by approximately 10%. Bystander CPR performed before professional help arrives significantly improves outcomes and can prevent permanent brain damage or death.

CPR Training and Certification

CPR training is available through the American Heart Association, American Red Cross, and other certified organizations. Training courses teach proper technique, include hands-on practice with mannequins, and provide certification typically valid for two years. Many employers, schools, and healthcare facilities require or strongly encourage CPR certification. Regular refresher training helps maintain proficiency and keeps participants updated on guideline changes.

Variations and Advanced Techniques

CPR variations include hands-only CPR (chest compressions without rescue breathing) and CPR using automated external defibrillators (AEDs). Healthcare providers perform advanced life support with medications and specialized equipment. Pediatric CPR differs slightly from adult CPR in compression depth and breathing technique. Different techniques may be appropriate depending on the victim's age, the rescuer's training, and circumstances of the emergency.

Related Questions

What is the correct CPR compression rate?

The correct compression rate is 100-120 compressions per minute. Guidelines recommend following the beat of the song 'Stayin' Alive' by the Bee Gees, which has approximately 103 beats per minute, to maintain proper rhythm and pace during compressions.

How long should CPR be performed?

CPR should be continued until emergency medical services arrive and take over, the person shows signs of life, you are too exhausted to continue, or an automated external defibrillator (AED) is used. Never stop CPR prematurely, as the person may still be revivable.

What is hands-only CPR?

Hands-only CPR involves performing chest compressions without rescue breathing. It is often recommended for untrained bystanders or those uncomfortable with rescue breathing, as it is effective for adult cardiac arrest and easier to perform under stress.
