[Effects of smoking on the external respiration system in adolescents and young adults].
The specific features of the function and apparatus of external respiration were studied in adolescent and juvenile smokers and non-smokers. Ninety three boys aged 14-16 years who were 8-10--form pupils and 130 young men aged 19-23 years who were University students were examined. It was found that 38.7% of schoolchildren and 26.2% were smokers. 61% of the non-smokers were recorded to be apparently healthy. This condition was encountered 1.2-1.6 times less frequently in the smokers. The same number of smokers and non-smokers were at risk for lung pathology that was detectable in the former 2-2.5 times more frequently. Most indices of the function and apparatus of external respiration were not different in the smokers and non-smokers and they were in the normal range. The exceptions were functional residual capacity and expiratory PO?? which are significantly higher in the smokers, which suggests that respiratory tissue is of higher airiness aimed at compensating for permanent or recurrent hypoxia.
