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 decompression status. 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 decompression time is
allowed for multilevel diving.
The Tissue Loading Bar Graph monitors 12 different nitrogen
compartments simultaneously and displays the one that is in
control of your dive. It is divided into a green No Decompres-
sion (normal) zone, a yellow Caution zone (also No Decom-
pression), and a red Decompression (danger) zone.
While you cannot provide a guarantee against the occurrence
of decompression sickness, you may choose your own per-
sonal zone of caution based upon age, physique, excessive
weight, etc., to reduce the statistical risk.
NOTE: Displays associated with oxygen and the
O2 Bar Graph will only appear if FO2 has been set
at a value other than 'Air' (e.g., a numerical value).
