[Lung volume, capacity and alveolar ventilation in smokers].
Pulmonary volume and capacity as well as the intensity of alveolar ventilation depending on the length of smoking were examined in 60 practically healthy smokers and 30 non-smoking males. It was established that smokers with a smoking length of 6-10 years revealed a significant increase of residual pulmonary volume, volume of breathing dead space and a reduction of the alveolar ventilation/minute pulmonary volume ratio indicating a reduction of the amount of ventilated air. The revealed changes are results of a reduction of the pulmonary elasticity due to development of restrictive disorders in the parenchyma.
