WARNING: In the event that you enter High PO2 Dive Mode, you must
immediately focus on reducing the partial pressure of oxygen by slowly
ascending to a shallower depth at a safe rate in accordance with your
nitrox training. If you continue the dive at your current depth, or descend
deeper, your exposure to CNS oxygen toxicity will increase.
OXYGEN ACCUMULATION
It is important that you understand that conducting repetitive dives using enriched nitrogen-oxy-
gen (Nitrox) mixtures can lead to increases oxygen saturation (O
2
SAT) and the risk of pulmonary
oxygen toxicity.
Genesis Scuba strongly recommends that you avoid exceeding oxygen exposure limits, and
reminds you that Nitrox diving requires special training and understanding of the effects of
oxygen toxicity.
During Nitrox dives, the current level of O2 saturation (%) with O2SAT icon is displayed on an
ALT screen (Fig. 61a).
Displayed will be either the percentage (%) of oxygen accumulated during that dive, or during the
repetitive dives you conducted during that 24 hour period, whichever of the two is calculated to be
greater at that time.
