It’s commonly done in some specific cases of people not breathing. Sleep apnea and opioid drug overdoses are two immediate examples I can think of.
With opioid drug overdoses, stimulation in general can be (temporarily) effective if they haven’t taken too much. Usually, they require more stimulation, such as sternal rubs or trapezius pinching, but I have seen cases where they needed someone to shout at them every 30 seconds or so.
