Risks of Diving: Residual Nitrogen

The residual nitrogen is nitrogen remaining in the body after a swim, whose time of delay to be deleted depends on dive time and depth. As a rule, the time between a swim and another is of 12 hours, but in special cases this time should be increased (for example, when it exceeds the limits of the non-decompression diving).

If the Elimination of the residual nitrogen is disabled (for health or external factors as a very fast rise) may occur generating nitrogen bubbles that cannot be eliminated from the human body, being retained in tissues or in the bloodstream. This occurrence is called decompression sickness.

The classic example of decompression sickness, known popularly as the “bends”, English: bend, is abrupt opening a bottle of soda or a bottle of champagne.

The gas pressure inside the bottle is mixed into the liquid without any visual indicator of your existence.

With the opening of the lid quickly, the carbon dioxide that was diluted in the liquid rapidly turns into bubbles, forming the characteristic foam.

On the contrary, if a tiny hole or an opening of equal size in Cork or in bottle cap, allowing the output of the gas slowly, there is the formation of bubbles.

Similarly, when breathed under pressure, nitrogen dissolves in the blood imperceptibly (remember that every 10 meters of depth there is an increase of one atmosphere of pressure).

The longer and deeper diving, the greater the concentration of nitrogen in the blood and tissues.

Maintained the same depth, or climbing-if slowly and with compliance with the decompression tables, not nitrogen turns into bubbles and is eliminated naturally by the body.

On the contrary, if there is a rapid ascent and/or without observing the limits imposed on the dive tables, diluted nitrogen in the blood ends up quickly turn into bubbles, which in your time, expand looking out too quickly in the blood and tissues.

The speed as the bubbles seek out of the blood and eventual training and stop these bubbles in the bloodstream can cause various injuries to the human body, since serious hemorrhages to cardio-respiratory stops and may lead the diver to death.

As simple and easy to understand rule, we could draw a line between dive time and depth, and as more progress in the dive duration and depth achieved, the greater the time so that the body can eliminate the bubbles of nitrogen form in the blood when air is breathed under pressure.

The first dive tables were made based on us Navy military and of course the same physical conditions were superior to a normal person (without physical training that were submitted).

Over time, new tables were being prepared, taking into account a diver without Prime physical condition of the military Navy.

With that, the tables presented top times for decompression (removal of nitrogen bubbles in the blood and tissues).

With easy access to hyperbaric chambers (chambers where the pressure is higher than the atmosphere, artificial and controlled regulated by technicians), made it possible to not only divers and military professionals and the amateurs, a more effective relief day diseases.
