What rule can help divers avoid nitrogen narcosis when using Nitrox?

The "Depth and Time" rule is essential for helping divers manage their exposure while utilizing Nitrox. This rule emphasizes the relationship between how deep a diver is and the duration of their dive. By keeping track of these factors, divers can better manage their nitrogen absorption and limit the potential onset of nitrogen narcosis, which is a condition caused by the effects of nitrogen under pressure that can impair cognitive and motor functions.

When using Nitrox, which has a higher proportion of oxygen compared to air, divers can extend their no-decompression limits at shallower depths. This allows them to make deeper dives with reduced nitrogen load, as Nitrox can lower the overall nitrogen exposure compared to air. By adhering to the "Depth and Time" rule, divers can effectively plan their dives, monitor their ascent rates, and ensure that they have ample surface intervals between dives. These practices help mitigate the risk of nitrogen narcosis and enhance overall safety while diving.

The other options do not adequately address the key factors associated with diving physiology and safety. For example, "Breath and Hold" is more related to buoyancy control and not directly related to the management of nitrogen narcosis. "Light and Easy" and "Dive and Dive" do not convey specific
