AMD and Maximum Operating Depth MOD are calculated from the oxygen content in the mix The ppO2 that is given by the user is divided by the oxygen fraction The result will be pressure which is converted to depth The maximum MOD is valid for all gases while the minimum AMD is only applicable to a gas mix where the oxygen fraction is less than air ce Note Air 21 0 gives different MOD than for example Trimix 21 10 The reason is Galileo uses a more precise value for the oxygen in the air which is 20 7 1 5 PDIS for both N2 and He Profile Dependent Intermediate Stop PDIS as described in the main manual has been extended to both Nitrogen and Helium gases The optimal off gassing depth will be indicated when PDIS is enabled PDI stops are not obligatory but will potentially assist in reducing possible bubble formation 1 6 Oxygen Toxicity Units OTUs During long decompression dives the divers body will be loaded with high oxygen concentrations for a longer period of time There are two limits that need to be monitored the Central Nervous System CNS clock described in main manual and the Oxygen Toxicity Units OTUs For OTU credits and limits the NOAA values are used 1 7 Ascent speed The optimal ascent rate is fast enough to prevent further compartment saturation but slow enough to prevent bubble formation in tissues When making decompression dives with mixed gases this becomes an important factor Gali
