[Status of the main functional systems in humans after long-term exposure to hyperbaric medium]. / Sostoianie osnovnykh funktsional'nykh sistem cheloveka posle dlitel'nogo prebyvaniia v giperbarichesko'i srede.

The exposure of divers to hyperbaric conditions under pressure of 4.6 MPa induced development of astheno-neurotic disorders with cardiovascular component against a background of pronounced fatigue. A decrease of the pulmonary ventilation function in the form of bronchial obstruction syndrome was observed as well. On the 10-15th day of the postdiving period asthenia phenomena extinguished and the pulmonary function tended to restoration. On the 30th day of postdiving period all the functional systems were normalized. The professional activity of divers for many years gives rise to the formation of adaptive reaction (increase of vital capacity of lungs and maximal ventilation of lungs), on the one hand, and to pathological disorders, such as arterial hypertension and bronchial obstruction syndrome, on the other hand.
