Dive Calculations

Decompression Calculations

Decompression calculations are essential for planning safe dives, particularly when diving beyond recreational limits or engaging in technical diving. These calculations help divers determine safe ascent profiles, minimizing the risk of decompression sickness by controlling how pressure changes with depth affect the solubility of gases in body tissues.

Bottom gas refers to the primary breathing gas used during the deepest part of a dive. Understanding how much bottom gas is needed is crucial for ensuring a diver has sufficient air supply for the planned dive depth and duration. Accurate bottom gas calculations aid in preventing abrupt interruptions underwater.

Ratio Deco (SP1) is a streamlined method of planning decompression schedules tailored for technical divers. By using Set Point 1, divers can simplify their calculations for ascent profiles, ensuring efficient and safe decompression strategies. This approach offers a straightforward way to estimate the necessary decompression time based on standardized ratios.
Warning: This method should only be used by individuals who have received proper education and training in technical diving. Always verify calculations with multiple sources and adhere to your training organization’s guidelines to ensure safety.
