Nitrox planning

Check blend, oxygen limit, and planned depth together

Compare air and nitrox blends, estimate MOD for a selected ppO2 limit, and check oxygen partial pressure at a planned depth.

Planning boundary: Nitrox results require proper training, cylinder analysis, correct computer settings, operator confirmation, and respect for oxygen exposure limits. They are not clearance to make a dive.
