What is a typical recommendation for deep dives in relation to air supply?

The recommendation to monitor air consumption closely during deep dives is crucial for several reasons. Deep diving increases the risks associated with pressure and the effects of nitrogen narcosis, and it demands greater awareness of your air supply. As the depth increases, air consumption typically rises due to pressure effects and physiological stress, which can lead to a quicker depletion of your air supply. By closely monitoring air consumption, divers can make informed decisions about their dive duration, manage ascent schedules, and ensure they have adequate air to safely complete their dive and return to the surface.

The importance of this practice is emphasized by the depth and environmental factors that can affect a diver's air use. Ensuring that you have a clear understanding of how much air you have left as you dive deeper allows you to mitigate risks effectively and prioritize safety above all.

Other recommendations, such as bringing additional safety supplies and breathing slowly, also contribute to dive safety but do not carry the same immediacy as monitoring air consumption. While these practices are beneficial, they do not directly address the critical need for maintaining an adequate air supply throughout a deep dive.
