Final answer:
For Adult CPR, compressions should be performed at a rate of 100 compressions per minute, maintaining a steady rate for as long as necessary until help arrives or the patient recovers, without calculating per-second compressions.
Step-by-step explanation:
For Adult CPR, it is recommended that chest compressions be given at a rate of 100 compressions per minute. This rate ensures that the patient receives continuous chest compressions, which is important for maintaining blood flow, particularly to the brain to prevent irreversible damage and death of neurons.
Since a minute contains 60 seconds, and you are to compress at a rate of 100 compressions per minute, you do not stop to calculate seconds per compression but instead maintain the steady rate throughout the entire minute without interruption until professional help arrives or the patient recovers.
