What complicates managing oxygen exposure for technical diving?
Why is monitoring oxygen exposure generally easy for technical divers?
Is it necessary for new tech divers to track Oxygen Tolerance Units (OTUs)?
Key Points to Remember
What complicates oxygen exposure for technical divers is the fact we generally expose ourselves to PO2 values above 1.4 ATA during the final phases of decompression.
Oxygen exposure is generally something your dive planning software will track for you. Similarly, oxygen tracking has been built into modern dive computers since the earliest Nitrox models in the mid-1990s.
Most experts don’t feel it’s necessary to track Oxygen Tolerance Units (OTUs) if only making a limited number of dives above 45 m/150 ft. Besides, it’s among the many things both your dive planning software and dive computers will most likely be tracking for you.
