When can CPR be discontinued?

The discontinuation of CPR is a critical decision that should be based on the victim’s condition rather than the rescuer's fatigue. The key indicator for stopping CPR is the return of spontaneous circulation, which is typically signified by the victim starting to breathe normally. If a victim resumes normal breathing, it indicates that the heart may have restarted, making it appropriate to cease CPR.

In situations where a backup rescuer arrives, it is crucial to assess the victim's condition rather than stopping CPR simply due to a change in personnel. While exhaustion is a valid concern for the rescuer, it’s essential to try to continue providing care until the victim shows definitive signs of life or emergency medical services take over. Rescuers are trained to prioritize the victim’s needs over their own exhaustion or the amount of time spent administering CPR.
