[State of human bronchopulmonary apparatus under hypobaric hypoxia and its adaptation to that condition]. / Sostoianie bronkholegochnogo apparata cheloveka pri gipobaricheskoi gipoksii i adaptatsii k nei.

The influence of hypobaric hypoxia (HH) on the bronchial tree smooth muscle state at 208 men was investigated. It was shown, that HH relaxes smooth muscle of bronchus, eliminating the phenomena of bronchismus, is activities mucocilsary clearance. The increase of the forced speed of an exhalation for 1 sec in one month after ending a course (2.5 + 0.25 l/sec against 2.1 + 0.13 l/sec) was marked. In 6 months after ending a course of HH the forced speed of an exhalation for the first second continues to grow and is statistically authentically above initial (2.6 + 0.15 l/sec). The increase of an Teffno index was marked which in 6 months of treatment comes nearer to 100% (97.5 + 6.1 against 79 + 2.6%).
