During CPR, what is the correct rate of chest compressions for an adult?

The appropriate rate of chest compressions for an adult during CPR is between 100 and 120 compressions per minute. This rate has been established based on research that indicates compressions at this frequency are most effective in maintaining blood flow to vital organs during cardiac arrest. The aim is to provide high-quality compressions that are both deep enough and at a rapid enough pace to mimic the heart's pumping action.

Compressions at this rate ensure that there is adequate circulation of oxygenated blood, which is critical for the survival of the person in cardiac arrest. Maintaining this rate, combined with a proper depth of compression, contributes to improving outcomes in resuscitation efforts.
