What is required if the oxygen supply in the chamber is lost temporarily?

When the oxygen supply in a chamber is lost temporarily, breathing chamber air is the appropriate response because the air within the chamber will still contain a mix of gases, including nitrogen, and possibly some residual oxygen. This air can still provide adequate breathing support while the oxygen supply is being restored. It is critical for maintaining normal physiological functions and preventing hypoxia until the situation can be remedied.

Switching immediately to air may not be advisable because the chamber may specifically be designed to maintain a certain mixture or pressure that is essential for treatment effectiveness. Continuing with treatment without oxygen could lead to serious complications, as the necessary levels of oxygen would not be provided to the patient. Deflating the chamber could also pose risks and complications, particularly if immediate pressure changes could affect the treatment process and the patient's condition. Therefore, breathing the chamber air remains the safest and most effective immediate action in this scenario.
