At altitude, the air pressure and hence the ambient pressure underwater are lower than at sea level. This leads to a lesser saturation of...

If the inert gas pressure of a tissue is less than its maximum tolerated value for the water surface, it is possible to ascend directly...

No decompression limit (NDL) means that it is possible to ascend from depth directly to the surface without affecting the supersaturation...

The supersaturation tolerance was explained in the previous article. To recap: It represents the limit at which bubbles form in a tissue...

Every diving course teaches the saturation and desaturation of tissues with inert gases. Unfortunately, the concept of supersaturation...
