What is the optimal compression rate during CPR?

The optimal compression rate during CPR is between 100 and 120 compressions per minute. This range allows for effective blood circulation during cardiac arrest, providing adequate blood flow to vital organs, especially the brain and heart. Compressions performed within this rate promote sufficient perfusion pressure, which is essential for maintaining oxygen delivery to these critical areas.

Performing compressions too slowly, such as within the range of 60 to 80 compressions per minute, can lead to decreased blood flow and insufficient oxygenation, increasing the risk of organ damage. Conversely, compressions exceeding 120 per minute may hinder proper chest recoil and can actually limit blood flow as well, rendering the efforts less effective. Thus, adhering to the recommended compression rate of 100 to 120 compressions per minute is crucial for maximizing the chances of survival during a cardiac event.
