An oxygen supplying apparatus includes: an oxygen enriching module including a plurality of oxygen enriching units; a pressure boosting module which receives the oxygen-enriched gas from the oxygen enriching module and boosts pressure of the oxygen-enriched gas; and a controller controlling operations of the oxygen enriching module and the pressure boosting module. The pressure boosting module includes: a low-pressure tank which receives and stores the oxygen-enriched gas from the oxygen enriching module; a pressure booster which boosts pressure of the oxygen-enriched gas discharged from the low-pressure tank; a high-pressure tank stores the oxygen-enriched gas pressure-boosted by the pressure booster; and at least one bypass valve which is provided to a bypass passage for bypassing a portion of the pressure-boosted oxygen-enriched gas stored in the high-pressure tank to the low-pressure tank to regulate bypassing of the oxygen-enriched gas from the high-pressure tank to the low-pressure tank.
