An adult isn’t breathing at the scene of a crash. To save the casualty, you must administer chest compressions. What is the correct chest compression depth?

Explanation: A compression depth of 5-6 centimetres is correct. Place both hands in the centre of the casualty's chest and give two chest compressions every second (120 per minute). This maintains circulation in adult casualties who aren't breathing properly.
