When starting CPR chest compressions on an unresponsive adult not breathing normally, after calling 112, on which part of the chest do you place the heel of your hand?

Correct answer

The sternum

In the centre of the chest, over the lower half of the sternum, with the other hand on top. For adults compress at 100–120 per minute and 5–6 cm deep, allowing full recoil and minimising interruptions. Follow 112 and use an AED when available. If trained and able to give breaths, use 30 compressions to 2 breaths; otherwise continue compressions. Do not begin by searching for bones without checking responsiveness, breathing and calling for help.
