The recommended number of chest compressions to be given in CPR is 30 compressions per cycle, at a rate of 100 to 120 compressions per minute. This is followed by 2 rescue breaths, then continuing the cycle of 30 compressions and 2 breaths until medical help arrives or the person recovers. If performing hands-only CPR without rescue breaths, the compressions should be continuous at 100 to 120 per minute. This guideline applies for adults, children, and infants in need of CPR.
