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
