At what rate should chest compressions be performed?

Chest compressions during cardiopulmonary resuscitation (CPR) are most effective when performed at a rate of 100 to 120 compressions per minute. This rate has been established as optimal by guidelines from organizations such as the American Heart Association, balancing the need for adequate blood flow with the need to minimize interruptions in compression.

Performing compressions within this range helps to ensure that blood circulation is maintained effectively, providing vital oxygen to the brain and other organs during a cardiac arrest. Compressions that are too slow may not generate enough blood flow, while those that are too fast can reduce the amount of time the heart has to fill with blood between compressions, leading to inadequate perfusion.

Maintaining a consistent rhythm, often suggested to align with the tempo of a familiar song (such as "Stayin' Alive" by the Bee Gees), can also help rescuers keep up the correct rate during CPR. Adhering to this guideline is crucial for maximizing the chances of survival and favorable outcomes in individuals experiencing cardiac emergencies.
