BAR GRAPHS
Tissue Loading Bar Graph (TLBG)
The Tissue Loading Bar Graph (Fig. 2a) represents tissue loading
of nitrogen, showing your relative no decompression or decom-
pression status.
The Tissue Loading Bar Graph monitors 12 different nitrogen
compartments simultaneously and displays the one that is in
control of your dive.
As your depth and elapsed dive time increase, segments will add
to the Graph, and as you ascend to shallower depths, the Bar
Graph will begin to recede, indicating that additional no decom-
pression time is allowed for multilevel diving.
It is divided into a green No Decompression (normal) zone, a
yellow Caution zone (also No Decompression), and a red
Decompression (danger) zone.
While you cannot provide a guarantee against the occurrence of
decompression sickness, you may choose your own personal
zone of caution based upon age, physique, excessive weight,
etc., to reduce the statistical risk.
