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
CO
will track the OTU based on Dr. Bill Hamilton’s ‘REPEX’ method of
