ABSTRACT:
An oxygen concentrating apparatus including an output variable type compressor. Oxygen-concentrated gas may be supplied either continuously or synchronized with inhalation or timing of inhalations. In one aspect, when synchronous operation is selected, the compressor is operated at a lower output in comparison with continuous supply operation. In a second aspect, when synchronous operation is selected, the supply quantity of oxygen-concentration gas is set to zero during the exhalation period.
