What is the recommended compression rate for adult CPR?

The recommended compression rate for adult CPR is 100-120 compressions per minute because this range has been shown to provide optimal blood flow during cardiac arrest. High-quality chest compressions are crucial in maintaining circulation and increasing the chances of survival for the individual in cardiac arrest. Compressions should be hard and fast, at a depth of at least 2 inches, to effectively pump blood to vital organs.

Research and guidelines from organizations such as the American Heart Association support this compression rate as it balances the need for adequate perfusion with the physical limits of the rescuer. Staying within this range helps ensure that compressions are sustained without becoming overly fatigued, thereby maintaining effective CPR. This compression rate also aligns with the ability to deliver efficient rescue breaths, if applicable, while minimizing interruptions to compressions.
