According to the American Heart Association (AHA) 2020 CPR guidelines, what is the recommended chest compression rate for adult cardiopulmonary resuscitation?

The 2020 AHA Guidelines for CPR specify a chest compression rate of 100-120 compressions per minute for adult CPR. This range represents the optimal rate: compressions below 100/minute are insufficient for adequate cardiac output, while rates above 120/minute reduce compression depth and diastolic filling time. In addition to rate, high-quality CPR requires: compression depth of at least 2 inches (5 cm) in adults, complete chest recoil after each compression, minimal interruptions (<10 seconds), and avoidance of excessive ventilation. Compression-to-ventilation ratio is 30:2 for single rescuers without an advanced airway.
