How many chest compressions should be administered during CPR?

During CPR, the current guidelines recommend administering 30 chest compressions for every 2 rescue breaths in adults, which is crucial for maintaining circulation and oxygenation until professional help arrives. This compression-to-breath ratio is designed to provide effective blood flow to vital organs, particularly the brain and heart, especially in a cardiac arrest situation. This method helps ensure that the necessary compressions are adequate for sustaining life while minimizing interruptions in circulation.

The numerical choice of 30 reflects the established practice that is widely accepted in CPR training and is supported by organizations such as the American Heart Association. It's important for caregivers and responders to adhere to this standard for optimal effectiveness during emergencies.
