A member asked:

How long can the heart stop before you get brain damage?

Specializes in Critical Care

Not very long: The brain is extremely sensitive to anoxia (being without oxygen). Depending on other medical issues, after approx 5 minutes brain damage can occur, which is why it is so important to begin CPR immediately.
