What is the function of the oxygen analyzer in a hyperbaric chamber?

Measure air pressure
Detect humidity
Monitor the fraction of oxygen in the chamber
Test for carbon monoxide

The correct answer is: Monitor the fraction of oxygen in the chamber

The function of the oxygen analyzer in a hyperbaric chamber is to monitor the fraction of oxygen in the chamber. Maintaining the proper oxygen concentration is crucial for the safety and effectiveness of hyperbaric oxygen therapy. A hyperbaric chamber operates at pressures higher than normal atmospheric pressure, and it is essential to ensure that the oxygen levels do not exceed safe limits. The oxygen analyzer continuously measures the partial pressure of oxygen to ensure that it remains within the therapeutic range, typically around 1.5 to 3.0 atmospheres, depending on the treatment protocol. This monitoring helps prevent potential complications, such as oxygen toxicity, which can occur if oxygen levels are too high. Being aware of air pressure, detecting humidity, or testing for carbon monoxide are important elements in hyperbaric treatment but are not the primary function of the oxygen analyzer. These measurements may be monitored by other devices and systems within the hyperbaric chamber environment. Therefore, the correct understanding of the role of the oxygen analyzer is critical for ensuring the safety and efficacy of treatments involving hyperbaric oxygen therapy.
