[The late sequelae of the systematic action of a complex of real diving factors on the pulmonary ventilatory function of deep-sea divers].
Parameters which characterize lung volumes, absolute and relative flow rates, breathing reserve, were found unchanged with increasing age and record of active dive service, and in some deep-divers these parameters were growing up. This was disclosed due to comparative analysis of lung ventilatory function changes in divers through certain amount of years of professional occupation. At the same time a significant decrease in small to middle calibre bronchi patency was noted. In 30% of experienced deep-divers the mean maximal forced expiratory flow at 75% forced vital capacity (FEF75) decreased to 39% of predicted value at one-second forced expiratory volume (FEV1) being normal. Maximal expiratory flow at 50% forced vital capacity (FEF50) were in inferior normal limit (52% of predicted value).
