What is the range of O2 percentage inside the hyperbaric chamber?

The range of oxygen percentage inside a hyperbaric chamber typically falls between 19-25%. This specific level is carefully regulated to ensure the patient receives sufficient oxygen for therapeutic purposes without causing oxygen toxicity, which can occur at higher concentrations.

In hyperbaric medicine, raising the ambient pressure allows for a higher partial pressure of oxygen, which enhances the body's ability to absorb oxygen into the bloodstream. The percentage of oxygen within this range ensures effective treatment while minimizing risks. Maintaining this balance is essential for patient safety and achieving the desired therapeutic outcomes.

A lower oxygen percentage, such as found in the first option, would not provide the necessary therapeutic effect, while higher percentages could lead to complications such as oxygen toxicity. Thus, the choice of 19-25% represents an optimal range for effective hyperbaric treatment.
