    Abstract: PROBLEM TO BE SOLVED: To provide an oxygen concentrator capable of guaranteeing a flow rate as prescribed, while securing the oxygen concentration of oxygen-enriched gas regardless of the environmental condition.SOLUTION: The oxygen concentrator includes a mass flow controller 22 including a mass flowmeter and a flow control valve, and a CPU 32 that corrects the flow rate set in the mass flow controller 22 to an accurate flow rate value at the air pressure of the usage environment based on the air pressure of the usage environment detected by an air pressure sensor 37, whereby the flow rate set in the mass flow controller 22 is corrected to a flow rate value that is based on the volume of a gas at the air pressure of the usage environment. Thus, oxygen-enriched gas can be supplied at the accurate flow rate matching the air pressure of the usage environment. Thus, an oxygen inhalation treatment as prescribed by the doctor can be achieved regardless of the altitude and temperature of a usage location. The oxygen concentration will not be lowered even in an environment at a high altitude or high temperatures, and the oxygen inhalation treatment with a stably maintained oxygen concentration can be carried out.
