Buddy breathing

I'm out of air:
Give me air now (emergency implied): pointing to the mouth with thumb and fingers together, moving hand back and forth a short distance.

Buddy breathing is a rescue technique used in scuba diving "out of gas" emergencies, when two divers share one demand valve, alternately breathing from it. To a large extent it has been superseded by safer and more reliable techniques using additional equipment, such as the use of a bailout cylinder or breathing through a secondary demand valve on the rescuer's regulator.
