BAR GRAPHS
Nitrogen Bar Graph
The Nitrogen Bar Graph (Fig. 1c) 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 Nitrogen Bar Graph monitors 12 different nitrogen compart-
ments simultaneously and displays the one that is in control of your
dive. It is divided into a green No Decompression (normal) zone, a
yellow Caution zone (also No Decompression), and a red Decom-
pression (danger) zone.
While you cannot provide a guarantee against the occurrence of de-
compression sickness, you may choose your own personal zone of
caution based upon age, physique, excessive weight, etc., to reduce
the statistical risk.
