A casualty isn’t breathing normally and needs CPR. At what rate should you press down and release on the centre of their chest?

Explanation: If a casualty isn't breathing normally, cardiopulmonary resuscitation (CPR) may be needed to maintain circulation. Place two hands on the centre of the chest and press down hard and fast - around 5-6 centimetres and about twice a second.
