What is an advantage of using higher mixtures of oxygen in Nitrox?

Using higher mixtures of oxygen in Nitrox, such as 32% or 36% oxygen, significantly reduces the percentage of nitrogen in the breathing gas. When divers use these higher oxygen mixtures, they experience a decreased nitrogen intake, particularly during deeper dives. This decrease in nitrogen absorption helps reduce the risk of nitrogen narcosis and decompression sickness because at greater depths, the pressure increases and nitrogen uptake in the body also increases. By providing a gas mix with less nitrogen, divers can enjoy longer bottom times at depths without accumulating excess nitrogen in their tissues, allowing for safer and more flexible diving profiles. This advantage is particularly important in considering the physiological effects of nitrogen on the body during diving activities.
