PPO₂
Oxygen toxicity MOD
For bottom-gas, deco-gas and CCR — individually selectable.
Calculate your blending requirements for Nitrox and Trimix gasses, and read off MODs based on PPO₂, narcosis and gas density. Imperial or metric. Ideal-Gas or Van der Waals. Save the mixes you actually use.
Plan single-mix Nitrox or full Trimix blends, with the option to start from an existing mix instead of an empty cylinder. Visual prompts catch invalid gasses and impossible mixes before you waste a fill.
Use the Ideal-Gas formula taught in courses, or switch to Van der Waals for higher accuracy on fills. User-selectable time-to-fill takes the guesswork out of mixing.
For bottom-gas, deco-gas and CCR — individually selectable.
Equivalent narcotic depth so you can keep your head clear.
Stay below the 6.2 g/L work-of-breathing limit.
Toggle between imperial and metric without re-entering your mixes. Your saved recipes adapt.
Save recipes by name. Pull them up later without re-typing your common blends.
