APPARATUS AND METHOD FOR OXYGEN DELIVERY

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 based on 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 calculated reduction rate calculated as ratio of the input prescribed flow and the target average consumed flow, and controls the delivery of oxygen based on the selected mode.
