What is the main benefit of using Nitrox compared to regular air while diving?
✔✔The primary benefit of using Nitrox is to extend bottom time by reducing nitrogen
absorption, which decreases the risk of decompression sickness.
How does increasing the oxygen content in Nitrox affect your maximum dive depth?
✔✔Increasing oxygen content in Nitrox reduces the maximum allowable depth due to the risk of
oxygen toxicity.
Why is it important to analyze your Nitrox tank before each dive?
✔✔Analyzing the tank ensures you know the exact oxygen percentage, which is critical for safe
dive planning and avoiding oxygen toxicity.
What does the term "Equivalent Air Depth" (EAD) mean?
✔✔EAD refers to the depth at which a diver using Nitrox absorbs the same amount of nitrogen
as they would using air at a greater depth.

, How can Nitrox reduce fatigue after diving?
✔✔Nitrox can reduce post-dive fatigue by lowering nitrogen levels in the bloodstream, leading
to less nitrogen absorption and off-gassing.
What is the role of an oxygen analyzer in Nitrox diving?
✔✔An oxygen analyzer is used to verify the percentage of oxygen in a Nitrox mix before diving
to ensure safety and proper dive planning.
What are the symptoms of oxygen toxicity underwater?
✔✔Symptoms of oxygen toxicity include visual disturbances, nausea, muscle twitching, and
convulsions, which can be life-threatening if not managed.
Why should you use a dive computer designed for Nitrox when diving with enriched air?
✔✔A Nitrox-compatible dive computer ensures accurate tracking of your oxygen exposure and
dive limits to prevent oxygen toxicity.
What is the recommended maximum partial pressure of oxygen (PPO2) for recreational Nitrox
diving?
