BDifficulty 2/5

In basic CPR for an adult who is unresponsive and not breathing normally, if trained and able to give rescue breaths, what compression-to-breath ratio is used?

Correct answer

30 compressions and 2 rescue breaths.

30 compressions and 2 rescue breaths, under the 2025 basic life support guidelines. Call 112, follow its instructions and use an AED as soon as available. Give only enough air for the chest to start rising, without excessive ventilation, and resume compressions with minimal interruption. If untrained or unable to give breaths, provide compressions following the dispatcher. This is not isolated breaths for any crash casualty or a fixed 3–4-second interval.
