What is the recommended range for maintaining chamber O2 levels?

The recommended range for maintaining chamber oxygen levels is crucial for ensuring the safety and efficacy of operations in enclosed environments where oxygen levels can differ from standard atmospheric conditions. In this context, the optimal range of 19-25% oxygen is recognized as safe and effective for human performance and health.

This range is beneficial because it provides sufficient oxygen for metabolic processes while also minimizing the risk of oxygen toxicity, which can occur at higher concentrations. The physiological needs of the human body are met adequately within this range, supporting cognitive and physical functions without adverse effects. Moreover, this level prevents complications associated with fire risks, as higher oxygen levels may increase flammability.

Maintaining O2 levels within this recommended range is essential in environments such as hyperbaric chambers, submarines, or any other controlled atmospheric systems where human presence is critical.
