How to decompress when hypoxia pressure is too high?

The decompression method in this case is as follows:

1. Oxygen is produced by high pressure, and oxygen and hydrogen are stored in different spaces.

2. Hydrogen is pumped away to generate electricity, and oxygen is planted to reduce the temperature.

3. When the oxygen concentration in the living area is low, open the door of the oxygen room, so that the oxygen can be discharged quickly.

4. If there is a black hole, unnecessary gas and liquid can be discharged, so that high pressure can be used to reduce the pressure.
