What is the recommended compression rate (per minute) for CPR?

The recommended compression rate for CPR is between 100 and 120 compressions per minute. This range is important because it maximizes the effectiveness of chest compressions in maintaining blood flow to vital organs during cardiac arrest. When the compressions are delivered at this rate, it helps to create enough pressure within the chest cavity to circulate blood effectively, thereby improving the chances of survival and reducing the risk of brain damage due to lack of oxygen.

Using a compression rate that falls outside this optimal range, such as slower rates (like 60-80 compressions per minute) or much faster rates (like 120-140 compressions per minute), can lead to inadequate blood flow or can even be counterproductive, causing fatigue and poor-quality compressions. Ensuring that compressions are delivered at the recommended rate, along with the correct depth and allowing complete chest recoil, is essential for effective CPR.
