Desaturation time is determined either by
oxygen toxicity, nitrogen saturation or the
regression of microbubbles, depending on
which requires the longer time.
If Aladin 2G detects a situation of increased
risk (due to the potential of microbubble
accumulation from previous dives or a
CNS O
symbol will appear on the display. The
duration of the no-dive warning is visible
in the dive planner menu. Aladin 2G
recommends this as minimum surface
interval in order to reduce the number of
microbubbles and/or to reduce the CNS O
