The recommended chest compression rate for adults during CPR is 100 to 120 compressions per minute. Compressions should be done at a depth of at least 2 to 2.4 inches (5 to 6 cm), allowing complete chest recoil between compressions. The common CPR ratio for adults is 30 chest compressions followed by 2 rescue breaths (30:2) for a single rescuer. If the patient is intubated, compressions are continuous without pause for breaths, and ventilation is given once every six seconds.
Key Points on Adult Chest Compression Rate:
- Rate: 100-120 compressions per minute
- Depth: At least 2 inches (5 cm), but not more than 2.4 inches
- Ratio: 30 compressions to 2 breaths (30:2) for a single rescuer
- Minimize interruptions in compressions
- Continuous compressions if advanced airway is in place, with 1 breath every 6 seconds
This guidance is based on the American Heart Association guidelines and supported by major health authorities such as the American Red Cross and Mayo Clinic.
