1. 第1题，共25题

   You are not able or not willing to give rescue breaths to an adult. What should you do?

   • AGive rescue breaths only, without doing any chest compressions
   • BPress on the belly instead of the chest, more gently and slowly
   • CDo no CPR at all and wait quietly for the paramedics to arrive
   • DGive compression-only CPR: push hard and fast in the centre of the chest
   显示答案

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

   Compression-only CPR is acceptable if you cannot or will not give breaths. It is far better than doing nothing.

2. 第2题，共25题

   When may you stop CPR?

   • AAfter 10 full cycles, because CPR does not help after that point
   • BAfter exactly 5 minutes, even if no help or AED has arrived yet
   • CWhen EMS takes over, you see an obvious sign of life, you are too tired, or the scene becomes unsafe
   • DAs soon as the person's skin starts to look pale, grey or blue
   显示答案

   答案: C. When EMS takes over, you see an obvious sign of life, you are too tired, or the scene becomes unsafe

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

    显示答案

    答案: A. As soon as one is available, for anyone who is unresponsive and not breathing normally
