For an adult, what is the recommended rate of chest compressions during CPR?

The recommended rate of chest compressions during CPR for adults is 100-120 compressions per minute. This range is based on extensive research indicating that high-quality chest compressions are essential for maintaining blood circulation and improving the chances of survival in a cardiac arrest situation.

Compressions at this rate help ensure adequate blood flow to vital organs, particularly the heart and brain. Compressions that are too slow (for example, at a rate of 80-100 per minute) may not be effective in creating sufficient pressure to circulate blood, whereas a rate that exceeds 120 compressions per minute may lead to decreased compression depth and a lack of effectiveness due to fatigue or insufficient time for the heart to fill between compressions.

The focus is on achieving the optimal balance of rate and depth to maximize the efficacy of CPR and improve outcomes for the patient. This guideline aligns with current best practices and recommendations from organizations such as the American Heart Association and the European Resuscitation Council, ensuring that responders are providing the best possible care in emergencies.
