摘要：
The oxygen delivery apparatus comprises: an oxygen tank an outlet valve unit configured to include a variable flow valve capable of variably controlling the amount of oxygen, a pressure sensor, and a control unit controlling the operation of the outlet valve unit on the basis of a signal from the pressure sensor in order to control the amount of oxygen delivered to a recipient. The control unit controls the outlet valve unit on the basis of the pressure signal and an oxygen delivery mode selected from among a plurality of preset oxygen delivery modes, receives a prescribed flow (that is a prescribed oxygen delivery flow) and a target average consumed flow, selects one of the plurality of oxygen delivery modes according to the size of a obtained saving ratio obtained as ratio of the input prescribed flow and the target average consumed flow, and controls the delivery of oxygen on the basis of the selected mode.
