Air Diving Supervisor Practice Exam

The correct response indicates that during an in-water treatment, the procedure for determining the number of air or oxygen stops due to the need for increased pressure involves multiplying by 1.5. This multiplier is utilized in hyperbaric medicine to adjust decompression schedules based on the level of pressure experienced during a dive and the specific treatment requirements.

Increased pressure can affect the duration of exposure to certain breathing gases such as oxygen, necessitating stops to safely allow the body to eliminate excess nitrogen and manage oxygen toxicity. By applying a multiplier of 1.5, divers and healthcare professionals can account for the physiological effects experienced at greater pressures, allowing for a safer return to surface pressures.

This method ensures that adequate time is allotted during decompression, which is critical for avoiding decompression sickness or other adverse effects associated with rapid ascent or inadequate decompression procedures. Thus, the application of the 1.5 factor effectively addresses the complexities of gas behavior under increased pressures and ensures adherence to safety protocols during treatment.
