Dive Computer Limitations

While the dive computer is based on current decompression research and
technology, you must realize that the computer cannot monitor the actual
physiological functions of an individual diver. All decompression schedules
currently known to the authors, including the U.S. Navy Tables, are based on
theoretical mathematical models, which are intended to serve as a guide to reduce
the probability of decompression illness.
1.1.3.

Nitrox

Diving with nitrox provides the diver with an opportunity to increase bottom times
or reduce the risk of decompression illness by reducing the nitrogen content in
the breathing gas mix.
However, when the gas mix is altered, the oxygen content of the mix is generally
increased. This increase exposes the diver to an oxygen toxicity risk not usually
considered in recreational diving. In order to manage this risk, the dive computer
tracks the time and intensity of the oxygen exposure and provides the diver with
information to adjust the dive plan in order to maintain oxygen exposure within
reasonably safe limits.
In addition to the physiological effects of enriched air on the body there are
operational considerations to be addressed when handling altered breathing mixes.
Elevated concentrations of oxygen present a fire or explosion hazard. Consult the
manufacturer of your equipment in regards to its compatibility with nitrox.
