What is the minimum, desired, and maximum overbottom pressure required from 131-190 FSW when diving the KM37?

In the context of diving operations with the KM-37 Portable Surface Supplied Diving System, understanding overbottom pressure is crucial for ensuring the safety and effectiveness of dives. Overbottom pressure is the pressure exerted on a diver at depth, which is essential for maintaining proper buoyancy and ensuring that the scuba equipment functions correctly.

The specific values for minimum, desired, and maximum overbottom pressure at the depths specified (131-190 feet of salt water or FSW) are important parameters that divers need to manage.

When diving in the range of 131-190 FSW, the desired overbottom pressure is set at 165 psi, which is a standard industry requirement for safe operations in that depth range. This pressure ensures adequate breathing gas is available and helps mitigate risks associated with diving at greater depths, such as nitrogen narcosis and oxygen toxicity.

Maintaining a minimum of 165 psi also allows for operational flexibility during the dive, as it provides sufficient margin for safety in case of variations in environmental conditions or diver demands. Setting both the minimum and maximum at 165 provides a clear and consistent guideline to follow while maintaining focus on safety protocols.

Understanding these parameters helps divers and dive supervisors to effectively plan and execute dives, ensuring that the diving
