Optimal Chest Compression Rate for CPR

Evidence-Based Recommendation for Compression Rate

The American Heart Association recommends performing chest compressions at a rate of 100 to 120 compressions per minute for adult victims of cardiac arrest (Class IIa, Level of Evidence B-NR) 1, 2
The 2015 AHA guidelines update first established the 100-120/min range based on emerging evidence showing potential adverse effects of rates outside this range 5, 6
The American Heart Association updated the previous 2010 guidelines which recommended a rate of at least 100 compressions per minute without specifying an upper limit 3, 4

Chest compression rates below 100/min are associated with decreased return of spontaneous circulation and reduced survival 7, 8
Rates above 120/min may reduce coronary blood flow and decrease the percentage of compressions that achieve target depth 7, 8
Data from the Resuscitation Outcomes Consortium suggest an optimum target between 100 and 120 compressions per minute, with rates above or below this range appearing to reduce survival to discharge 7

As chest compression rates increase beyond 120/min, compression depth tends to decrease in a dose-dependent manner 5

Five main components of high-quality CPR have been identified: chest compression fraction, rate, depth, chest recoil, and ventilation 8
For optimal outcomes, chest compressions should be performed at a rate of 100-120/min 9, 1
Chest compressions should be performed to a depth of at least 2 inches but not exceeding 2.4 inches 1, 2
Chest compressions should be performed with complete chest recoil between compressions 1, 2
Chest compressions should be performed with minimal interruptions (chest compression fraction >80%) 7, 8

The current 100-120/min recommendation represents the best balance of factors affecting mortality and morbidity outcomes 9, 10

Audiovisual feedback devices may be reasonable to use during CPR for real-time optimization of compression rate and other quality metrics 1, 2
Rescuers should rotate the compressor role approximately every 2 minutes to maintain high-quality compressions, as compression depth begins to deteriorate after 90-120 seconds 1, 2

Focusing solely on compression rate without considering depth, recoil, and minimizing interruptions 1
Compressing too slowly (<100/min), which reduces blood flow and decreases chances of successful resuscitation 7, 8
Failing to rotate compressors regularly, leading to fatigue and deterioration in compression quality 1, 2
