By the accepted definition of CNS toxicity, should a PO2 value of greater than 1.6 ATA
be measured, the CNS Toxicity will be 100%. During the Surface Interval, this
percentage will decrease as the CNS declines toward zero. Once this has dropped
below 50%, the MAX DEPTH reading will return. Whatever the current CNS Toxicity
level, it can also be viewed in the Programming Mode.

OXYGEN TOLERANCE UNITS (OTU): An issue with long term breathing of higher
partial pressures of Oxygen above 0.5 ATA is Pulmonary Oxygen Toxicity or sometimes
called WHOLE BODY which must be tracked properly.
The COMMANDER+ will track the OTU based on Dr. Bill Hamilton’s ‘REPEX’ method of
