MULTIPLE TISSUE TRACKING
The DataMax Sport tracks twelve tissues compartments with half-times
ranging from 5 to 480 minutes. The Tissue Loading Bar Graph always
displays the controlling compartment (that is the only one important at that
time). Think of the Tissue Loading Bar Graph as twelve separate transpar-
ent displays laid on top of one another (Fig. 34). The tissue compartment
that has filled up fastest is the only one the viewer can see from the top.
At any particular point, one tissue compartment may be absorbing
nitrogen, while another that was previously higher may be off-gassing.
Figure 35 illustrates the point at which one compartment “hands over”
control to another at a different depth. Though two tissues were controlling
the diver at different depths, the Tissue Loading Bar Graph remains the
same because it displays only the highest loading of the 12 compartments.
As time goes on, or you reach a new depth, there may be sufficient off
gassing of the tissue compartments to reduce the number of all bar graph
segments. After the dive, the Tissue Loading Bar Graph reading that was
recorded at the end of the dive is shown in the Dive Log.
REPETITIVE DECOMPRESSION DIVING
The decompression model used by the DataMax Sport is based on the no-
decompression multi-level repetitive dive schedules successfully tested by Dr.
Ray Rogers and Dr. Michael Powell. These tests did not include repetitive
