[Results of utilization of intermittent normobaric hypoxia in patients with bronchial asthma and chronic obstructive bronchitis].

The results of intermittent normobaric hypoxytherapy in 42 patients with bronchial asthma (BA) and 14 patients with chronic obstructive bronchitis (COB) are analyzed. The positive effect is obtained in 76% of patients with BA and 92.8% of patients with COB. In the group of patients with BA the best effect was achieved for atopic form of BA--in 90% of patients, the effect was less pronounced for infection-allergic form--in 73.9% and for mixed form of BA--in 66.7%. In the process of treatment the attacks of asphyxia disappeared or became more occasional in 60.7% of patients; in 32.1% the attacks were more easily arrested or stopped independently; 33.8% of patients decreased doses of constantly taken drugs; in 33% cough ceased or decreased, sputum became to expectorate better; in 41% of patients dyspnea disappeared and considerably decreased. Improvement of the state in 54% of patients was retained for one year and more, in 29%--for 6 months, in 16.6%--for 3-4 months. The course of treatment consisted of 20-25 sessions. The patients breathed in hypoxic gas mixture containing 10% of oxygen (HGM-10) under intermittent conditions alternating with respiration of free air.
