under decompression or decompression, disease understanding disturbances in the body, resulting from too rapid reduction of excess pressure.The latter causes the supersaturation of blood and tissue gases (primarily nitrogen).The degree of saturation of tissues with nitrogen depends on the rate of release of the body from nitrogen outlet of the high pressure zone.Thus nitrogen excreted into the blood and tissues lungs is exhaled.If the transition from high pressure to normal too quickly, due to the great difference between the partial pressure of nitrogen in the environment and the partial pressure of nitrogen dissolving in the tissues of the body, it will be released into the blood with the rapid formation of bubbles.Unless these bubbles are small, they are carried away with the blood flow to the lungs, which are shredded and removed from the body, but if these bubbles exceeds the lumen of a blood vessel, vascular occlusion can occur - aerotromba formation and embolism development.All this leads to the
Clinic decompression sickness
Mild manifests itself in the form of extremely severe pain in any joint or multiple joints.Often accompanied by itching pain in the legs, back, shoulders, rarely in other places, sometimes itching appears before the pain, being their harbinger.
In moderate disease, Meniere's syndrome can occur, which is manifested dizziness, vomiting, nystagmus, loss of balance (the result of gas embolism in the maze), sharp pains in the abdomen due to flatulence, defecation reinforced.Severe
characterized by the presence of emboli in the blood vessels to vital organs: in the central nervous system, the heart and lungs.Clinically, there may be a myocardial infarction, and pulmonary, mono- and paraplegia, blindness.These forms of the disease are rare.
There is also a chronic decompression sickness.Distinguish primary chronic form when the disease develops gradually, without acute manifestations (clinically observed deforming osteoarthritis, myocardial and nervous system), and the secondary, when the process of developing as a result of undergoing an acute form of the disease (clinically they often manifest lesion of the spinal cord and the syndrome of Meniere).
All forms of decompression sickness can be treated easily if it is promptly initiated and carried out correctly.At the first sign of decompression sickness stricken immediately placed in the medical gateway in conditions of high atmospheric pressure (recompression).The essence of the therapeutic recompression is rapidly raising the pressure in the medical gateway to a level at which the symptoms of the disease disappear.This enables the tissues freed from the accumulated gas bubbles, which diffuses into the blood, and dissolved therein at a slow decompression is then gradually released through the pulmonary alveoli.After the release of the medical gateway recommended hot dry air or warm water baths, physiotherapy (solljuks, quartz, and so on. P.), Cardiac agents.
additional adverse factors are physical stress, cooling, UV radiation.
