title: [An intelligent photoelectric oxygen-inhalation calculagraph].
abstract: This paper introduces a self-made intelligent oxygen-inhalation accumulative calculagraph. A photoelectric probe is fixed on the buoy of the oxygen flowmeter under non-ventilation conditions.When the oxygen flowmeter is switch on, the buoy floats up, the oxygen supply begins and the timing starts at the same time. When oxygen inhalation pauses, the buoy goes down and the timing stops. When oxygen inhalation starts again, the timing continues and accumulates.
