1. A training device that simulates one or more oxygen malfunctions in aircraft flight, comprising:
a training device configured to be operably coupled to a flight simulator, the training device comprising:
an oxygen-depleted breathable gas source;
a switching valve in fluid communication with the oxygen-depleted breathable gas source;
an oxygen pump for delivering oxygenated breathable gas or normal-oxygen-content breathable gas, the oxygen pump in fluid communication with the switching valve;
a low-pressure accumulator in fluid communication with the oxygen pump;
a normal-oxygen-content breathable gas source in fluid communication with the low-pressure accumulator;
an oxygen source in fluid communication with the low-pressure accumulator;
a high-pressure accumulator in fluid communication with the switching valve;
a forward pressure regulator in fluid communication with the high-pressure accumulator; and
a mask in fluid communication with the forward pressure regulator;
wherein the training device is configured to disrupt a supply of breathable gas to the mask by providing reduced oxygen breathable gas to the mask or by modifying a breathable gas flow rate to the mask;
wherein the training device is configured to monitor one or more physiological or cognitive responses of a subject wearing the mask or to allow one or more physiological or cognitive responses of a subject wearing the mask to be monitored; and
wherein the training device is configured to permit the subject wearing the mask or an attendant or an operator of the training device to correct an oxygen malfunction in simulated aircraft flight.
