Decompression information is calculated according
to the diver‘s individual behaviour and decrease in
skin temperature. The decrease in skin temperature
is based upon the water temperature and the dive
time. By considering these changes in saturation,
the time that must be spent at the surface
prior to flying may be
considerably increased,
depending upon
the
depth,
time, and
temperature
of a dive, as
well as the
diver‘s behaviour
during that dive.
4 The Calculation Model ZH-L8 ADT
4.1 Description
The Aladin ® Pro Nitrox uses a new decompression
calculation model known as the ZH-L8 ADT. This model
uses eight compartments or “tissue“ groups with
nominal half time periods from 5 to 640 minutes.
This model differs considerably from other models
by its consideration of the following addi-
tional physiological processes:
1. Blood perfusion to the body‘s
organs is not constant. Skin and
muscle tissues are in particular subject
to changes in blood perfusion,
depending on temperature and
workload. Changes in blood perfusion to
these organs change their nitrogen saturation
tolerance. The model used by the Aladin
® Pro Nitrox
takes these effects into account and thus the
“skin“ and “muscle“ compartments in the Ala-
din
®
Pro Nitrox show variable half-time periods
and saturation tolerances.
