What effect does oxygen enrichment have on a diver's sensory perception?

Oxygen enrichment, commonly associated with enriched air or Nitrox diving, does have notable effects on a diver's sensory perception, particularly in terms of enhanced visual acuity and increased awareness. When divers use Nitrox, the higher partial pressure of oxygen can improve their overall cognitive function and physical performance at certain depths. This is attributed to oxygen's vital role in energy production within the body's cells, leading to increased metabolic efficiency. As a result, divers may experience sharper visual acuity and heightened alertness during dives.

In this context, the benefits of boosted awareness and attentiveness allow divers to better interpret their surroundings, notice details more clearly, and react promptly to changes in the environment. This can significantly improve their overall safety and enjoyment during dives, making them more effective in managing dive situations.
