- Give compression-only CPR: push hard and fast in the centre of the chest

Pregunta 2 de 25
When may you stop CPR?
- After 10 full cycles, because CPR does not help after that point
- After exactly 5 minutes, even if no help or AED has arrived yet
- When EMS takes over, you see an obvious sign of life, you are too tired, or the scene becomes unsafe
- As soon as the person's skin starts to look pale, grey or blue

Keep going until one of these things happens. Stopping early cuts off blood flow to the brain.
