Abstract: There are provided a gas supply apparatus and a gas supply method that are capable of supplying hydrogen gas of a highly accurate and stable hydrogen gas concentration to a body. A ventilator 100 that supplies oxygen-containing gas and hydrogen gas includes a hydrogen gas delivery unit 8 that delivers the hydrogen gas taken in to outside of the ventilator 100, and a control unit 22 that adjusts an amount of the hydrogen gas taken into the hydrogen gas delivery unit 8. The control unit 22 adjusts the amount of the hydrogen gas taken into the hydrogen gas delivery unit 8 based on a flow rate of the oxygen-containing gas.
