Once someone has started giving chest compressions, when should they stop?

ایک بار جب کسی نے سینے میں دباؤ دینا شروع کر دیا تو وہ کب روکے؟

When they get tired and their arms start to ache

When the ambulance crew arrives, and say they will take over

After they’ve been going for a few minutes

All of the above

Continue CPR (chest compressions and rescue breaths) until emergency medical personnel arrive and take over.

Don't stop unless they tell you to, as every minute counts in saving the person's life.
