What is the recommended rate of chest compressions for CPR?

The recommended rate of chest compressions for CPR is between 100 to 120 compressions per minute. This rate is effective because it ensures that blood is circulated adequately throughout the body, particularly to vital organs like the brain and heart, during cardiac arrest.

Compressing at this rate optimally balances the need for adequate blood flow while also allowing enough time for the chest to recoil between compressions, which is crucial for maintaining blood circulation. Keeping the compressions within this range has been shown to improve survival rates and outcomes after cardiac arrest.

In contrast, lower rates, such as 60 to 80 or even 80 to 100 compressions per minute, would not provide sufficient blood flow to support the body's needs during a critical situation. Similarly, compressing at a rate higher than 120 compressions per minute can lead to adverse effects and may actually hinder effective circulation due to insufficient recoil time.
