What potential benefits are there to using the same dive tables as for diving on air?

Using the same dive tables for diving on air, even when utilizing enriched air nitrox, presents several potential benefits that contribute to effective dive planning and safety.

Firstly, the dive planning process is simplified. Familiar dive tables allow divers to use known data without having to switch to different calculations or charts for varying gas compositions. This familiarity can lead to quicker decision-making and ease of planning dives, which is particularly valuable when divers are focused on multiple aspects of their dive.

Secondly, employing traditional dive tables can help ensure a greater safety margin when planning dives using nitrox. The dive tables are based on air, and while enriched air has a different oxygen content, sticking to these tables can effectively reduce the chances of overextending dive time or reaching depths that could increase the risk of oxygen toxicity. By sticking to air dive limits, divers maintain a buffer that enhances their overall safety.

Lastly, using air dive tables may contribute to a reduced risk of decompression sickness (DCS). Nitrox has an increased proportion of oxygen, which can afford a greater resistance to nitrogen absorption. When combining this physiological aspect with dive planning that aligns with air limits, divers lower their risk of nitrogen loading and subsequent DCS.

Given these considerations, it becomes clear that utilizing the
