practical to stay within the 11 minutes of no-decompression time allowed at
130 feet. If you exceed 160 feet, watch the Sport closely because you will
enter decompression rapidly. The Tissue Loading Bar Graph will alert you
when entering decompression by entering the red zone (Fig. 22) and chang-
ing dive time remaining from NDC to DEC.
EMERGENCY DECOMPRESSION
After entering decompression (especially at deeper depths) the Tissue
Loading Bar Graph may fill the 10, 20, 30, and 40 FT STOP decompression
zones rapidly. Once you’ve entered decompression,
it is imperative that
you ascend toward the required decompression ceiling immediately.
If you continue to dive at a deeper depth, your exposure to decompression
sickness will increase, and you risk entering violation mode and losing
information needed to properly ascend.
Whether at 160 feet on a first dive, or 60 feet on a third dive, it is possible
to quickly enter decompression if you’re not careful. Decompression is to be
avoided because you cannot ascend directly to the surface without potentially
dire consequences. If your equipment failed, requiring you to surface imme-
diately, you would risk decompression sickness. Your buddy would be unable
to lend assistance without also risking decompression sickness. Decompres-
sion diving requires special training and equipment to do properly. For these
reasons, decompression sport diving should be avoided.
