What Is a Hypoxic Chamber?

Explosive hypoxia is a very rapid and extremely severe hypoxia that occurs within seconds of a sudden interruption of oxygen supply. In aerospace, the risk of explosive hypoxia is high for occupants due to the sudden loss of pressure in the pressurized enclosed capsule.

Explosive hypoxia is a condition that occurs within seconds after a sudden interruption of oxygen supply.

The severity of explosive hypoxia depends on the final height of the exposure, the method of exposure, the oxygen concentration of the inhaled gas before exposure, the amount of oxygen stored in the body, ambient temperature, physical condition, physical activity, age, physiological training experience at altitude, and hypoxic training Situation etc ^[1]

The fundamental protective measure in space is that astronauts wear space suits in advance and immediately pressurize and supply oxygen. It is also extremely important to prevent accidental pressure loss in the cockpit ^[2] .
