What is the correct compression rate for adults during CPR?

The correct compression rate for adults during CPR is 100-120 compressions per minute. This rate is based on guidelines from the American Heart Association (AHA) and is designed to maximize blood flow during cardiac arrest. At this compression rate, it is easier to maintain effective circulation by creating a sufficient pressure gradient to ensure blood reaches vital organs.

This compression rate also aligns with rhythm that helps rescuers maintain consistency and effectiveness in delivering chest compressions. Performing compressions at a rate of 100-120 per minute has been shown to significantly improve the chance of survival when combined with other critical elements of CPR, such as proper depth and allowing full chest recoil between compressions.

The emphasis on this range stems from research indicating that rates lower than 100 compressions per minute may not provide adequate blood flow, while rates higher than 120 can lead to fatigue and reduce the quality of compressions, potentially hampering the effectiveness of resuscitation efforts. Therefore, following the guideline of 100-120 compressions per minute is crucial for effective CPR in adults.
