Chest compressions during CPR should be performed at a rate of 100 to 120 compressions per minute. This rate is supported by multiple authoritative sources, including the American Red Cross, the American Heart Association, and other resuscitation guidelines. The compressions should be done hard and fast, allowing for complete chest recoil between compressions, and minimizing interruptions to maintain effective blood flow. Research shows this range optimizes the chances of survival by balancing sufficient compression depth and rate to maintain circulation without compromising the quality of compressions. Rates faster than 120 per minute may reduce compression depth and lower the chance of successful resuscitation. Using a metronome or rhythm like the song "Stayin' Alive" can help maintain the correct pace. In summary, chest compressions should be done at 100 to 120 compressions per minute, pressing hard and allowing full chest recoil, with minimal interruptions for the best CPR outcomes.
