How many breaths does an adult get during one cycle of CPR?

During one cycle of CPR, which consists of 30 chest compressions followed by 2 rescue breaths, an adult receives 2 breaths. This ratio is used to ensure that oxygen is delivered effectively to the lungs while maintaining blood circulation through compressions. CPR should be performed at a steady rhythm, typically at a rate of about 100 to 120 compressions per minute.
