DECOMPRESSION MODEL
The Decompression Model
used by the XP 5 is based on the
no decompression multilevel repetitive dive schedules suc-
cessfully tested by Dr. Ray Rogers and Dr. Michael Powell.
These tests did not include repetitive dives deeper than 90
feet (27 meters) or decompression dives. Due to the
present unavailability of statistical data, XP 5 decompres-
sion predictions are based on U.S. Navy theory.
TISSUE COMPARTMENT CONTROL
The XP 5 tracks twelve tissue compartments with halftimes
ranging from 5 to 480 minutes. The Nitrogen Bar Graph al-
ways displays the controlling compartment that is the only
one important at that time. Think of the Nitrogen Bar Graph
as twelve separate transparent displays laid on top of one
another. The compartment that has filled up fastest is the
only one the viewer can see from the top.
At any particular point, one compartment may be absorbing
nitrogen, while another that was previously higher may be
off-gassing. Figure 96 illustrates one compartment
“handing over” control to another compartment at a different
depth.
This feature of the Decompression Model is
the basis of multilevel diving, one of the most im-
portant contributions the XP 5 offers you.
