IANTD Enriched Air (Nitrox) Practice Exam – Prep, Questions & Study Guide

In the event of a diving computer failure while using Nitrox, returning to dive tables for no-decompression limits (NDL) calculations is a suitable intervention. Dive tables are invaluable references that provide essential information about permissible dive times and depths based on the chosen gas mix and the depth of the dive.

If the diving computer becomes inoperative, the diver can utilize these tables to assess their situation and make informed decisions about their dive. This approach ensures that the diver remains within safe limits for nitrogen absorption, allowing them to avoid potential decompression sickness.

Utilizing dive tables can also help the diver in planning their ascent and safety stops, which is crucial for safe diving practices. The reliance on established tables provides reliability and consistency in managing dive profiles, especially when electronic devices fail.
