“How can we revive a person who passes out?”

You should strongly consider calling 911 if someone "passes out" and there is any suspicion that something other than alcohol (alone) is the cause--other drugs, diabetes, trauma, infection, etc. If someone drinks enough alcohol to cause them to lose consciousness, it is concerning as they may still be absorbing alcohol from what they drank, which may increase their alcohol level even higher, and become a threat to their life. There is no method to "un-drunk a drunk" other than time. The wives' tale about coffee might make them a TINY bit more alert, but still very intoxicated, and not likely able to help care for themselves or move safely without fall risk, etc. Same goes for other stimulant drugs/energy drinks/etc. Best option is to place the person on his/her side, with lower arm extended upward and head resting on it, and legs spread to increase balance and stability of staying in that position. This can be done up against a piece of furniture or wall to provide extra support. That way, if they should vomit, it will drain out, and not cause them to choke.

The first step is to secure the airway - make sure that the person is breathing. Then check for a pulse, and if there is none, immediately call for help and start CPR.

Secure the airway

You can't. Enough alcohol causes general anesthesia. IF you were a surgeon, you could probably remove their appendix without waking them up. The thing to watch out for is if their breathing slows or they start to turn blue. Then this could become a fatal overdose. Call 911!
