The calculation formula are based on the work of Dr. Buhlmann with RGBM folding by Dr. Bruce Wienke. Future inclusion of Dr. Wienke's RGBM. Simple models use symmetrical tissue loading/unloading rates (L=U). Complex models use asymmetrical tissue loading/unloading rates (L>U).

Average Depth

• Air: Air, Multi-dive, Multi-day.
• Nitrox: 21% to 99% NITROX, Multi-dive, Multi-day.
• Helium: Helium/Oxygen (95%/5% Max He/O2 ratio) , Multi-dive, Multi-day.
• Multi-gas: Nitrogen/Helium/Oxygen (ref 2.3 for max ratio), Multi-dive, Multi-day.
• Oxygen: 5% to 100% dependant on usage depth. PPO2 Mix 0, initiates constant PPO2 operation. PPO2 range 0.4 to 1.8.

Calculation Formula Range: 0 - 9 Calculation Formula is diver selectable prior to the dive. Adjustments to the decompression algorithm compensate for factors which increase the risk of decompression sickness. Some of the factors are workload, water temperature, physical condition, age, weight, etc. The conservation factor is recommended by the software interface program after completing the diver profile.
