One cycle of CPR for an adult includes how many compressions and breaths?

One complete cycle of CPR for an adult consists of 30 chest compressions followed by 2 rescue breaths. This ratio is based on guidelines established by the American Heart Association and is designed to maximize blood flow and oxygen delivery during cardiac arrest situations.

The 30:2 compression-to-breath ratio allows for a consistent rhythm that helps maintain effective circulation while minimizing interruptions in compressions. Compressions should be at a depth of at least 2 inches and delivered at a rate of 100 to 120 compressions per minute. After performing compressions, providing 2 breaths helps ensure that the patient receives oxygen, which is crucial for brain and organ function until professional medical help arrives.

This standard is critical for initiating effective CPR and increases the chance of survival and recovery for individuals experiencing cardiac arrest. It’s important for responders to remember this ratio to perform CPR effectively in emergency situations.
