Oxygen toxicity
Aladin 2G calculates oxygen toxicity based
on depth, time and the gas mixture and
displays it in the location of the ascent rate.
The toxicity is expressed in 1% increments

3.4.9 Nitrogen loading bar graph

The
graphical representation of how close to
decompression you are. As you absorb
nitrogen during the dive, more and more
segments of the bar will light up. Depending
on your depth, the segments can light up
more or less rapidly.

NOTE:
• During an ascent and if the CNS O
value does not increase anymore
(due to a lower partial pressure
of oxygen), the audible warning is
suppressed.
• During the ascent, the display of the
oxygen toxicity is replaced by the
ascent rate. If the ascent is stopped,
the display changes back to the
indication of the CNS value.
• Aladin 2G will display CNS O
values exceeding 199% with 199%.
