What does "completion pressure" refer to in cavern diving?

"Completion pressure" in cavern diving specifically refers to the pressure needed to successfully complete a complex circuit within the dive environment. This term is critical for divers to understand, as it relates to the changes in pressure experienced during the dive and the physiological implications associated with those changes.

When exploring or navigating through a cavern, divers often encounter varying depths and pressure changes, which must be managed properly to ensure safety and success. The concept of completion pressure encompasses the necessary pressure considerations that allow a diver to finish the planned dive safely, which includes managing their buoyancy and air consumption throughout the dive.

Understanding completion pressure is vital for divers, as it aids in the planning of dives, particularly in complex environments, allowing them to anticipate required adjustments based on their depth and location in the cavern. Thus, it plays a significant role in dive planning and execution, helping divers make informed decisions to ensure a safe return.
