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 com-
partments 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 Decompression (danger)
zone.
While you cannot provide a guarantee against the occur-
rence of decompression sickness, you may choose your
own personal zone of caution based upon age, physique,
excessive weight, etc., to reduce the statistical risk.
