In basic life support, what is the recommended compression-to-breathing ratio for adult CPR for a single rescuer?

• A. 30 compressions to 2 breaths.
• B. 15 compressions to 2 breaths
• C. 50 to 2
• D. 10 to 2

Answer: (A)

In adult basic life support for a single rescuer, the recommended sequence is thirty chest compressions followed by two rescue breaths. This balance keeps blood flowing to vital organs, since continuous compressions are the most critical part of CPR, while the breaths provide necessary oxygen to the blood. Deliver each breath in about one second and resume compressions quickly to minimize interruptions. If you’re unable to provide breaths, performing hands-only CPR with continuous compressions at the right rate still offers a lifesaving benefit.
