In a safe place, an adult is unresponsive and not breathing normally, and 112 has been called. If you are trained and able to give rescue breaths, what compression-to-ventilation sequence should you use for CPR?

Correct answer

Start with 30 compressions followed by 2 rescue breaths, repeating 30:2.

Start with 30 compressions in the centre of the chest, then give 2 rescue breaths; repeat 30:2. For adults, compress at 100–120 per minute and 5–6 cm depth, allowing chest recoil. Use an AED when available and follow its and the 112 dispatcher’s instructions. If unable to give breaths, give continuous compressions. Minimise interruptions; continue until normal breathing and signs of life return, professionals take over or you cannot continue. Do not delay compressions for unnecessary relocation.
