You’re performing cardiopulmonary resuscitation (CPR) on a casualty. How fast should chest compressions be?
- A Once per second
- B Twice per second
- C 3 times per second
- D Once every 5 seconds
Why this is the answer
When performing CPR, you should press down hard and fast in the centre of the casualty’s chest. You should aim for about 2 compressions per second and keep going until the casualty starts breathing normally or a healthcare professional takes over.
Why the other answers don't fit
- A
- Once per second — Half the rate that is needed.
- C
- 3 times per second — Faster than the chest can refill between compressions.
- D
- Once every 5 seconds — Far too slow to move any blood at all.
