Diving Problems that SCUBA Diver Faces Underwater in Ascent & Descent

Problems Of Inert Gases: Inert gases combine with other elements only with difficulty. However, when a breathing gas is inhaled the inert gas, in practice nitrogen or helium, can diffuse into the blood in the same way as oxygen. The presence of inert gas in the bloodstream gives rise to the problems of decompression, which will be discussed in another article, and when the inert gas is nitrogen there are also problems of narcosis.


The term decompression applies to a decrease in pressure either from atmospheric pressure to sub-atmospheric, as when ascending to altitude in an aircraft, or from raised pressure back toward sea level, as when leaving the bottom and starting the ascent after a dive. The importance of decompression lies in the effect it has on the dissolved gas in the body.


SCUBA Divers face problems related to inert gases during ascent and descent. The diffusion of inert gases, particularly nitrogen or helium, into the bloodstream, can lead to decompression issues and nitrogen narcosis. Decompression plays a vital role in managing dissolved gases within the body.
