Influence of the breathing methods of the heated oxygen-helium mixture on the indicators of variability of the heart rhythm and functions of external respiration in military servers with chronic obstructive

Abstract

The purpose of the research was to study the effectiveness of using heated oxygen-helium mixture in the medical rehabilitation of patients with chronic obstructive bronchitis.
 Material and methods. The study included 68 patients aged 32 to 56 years (43.7 4.1 years). The first group (n = 33) contained of practically healthy volunteers and the second group (n = 35) of patients with a verified diagnosis: chronic obstructive bronchitis, moderate to moderate degree of obstruction, the duration of the disease ranged from 2 to 16 years (5.4 1.4). In both groups, heated oxygen-helium mixture was used (the temperature of the mixture in the mask was 50С). Patients of the second group 30 minutes before inhalation of the heated oxygen-helium mixture used short or long-acting bronchodilators. The study was carried out before the start of therapy, after 5, 10 procedures. Estimated indicators of heart rate variability and respiratory function.
 Results and conclusion. The use of heated oxygen-helium mixture allowed to increase the activity of the parasympathetic department of the autonomic nervous system and reduce the tone of the sympathetic department, normalize the functioning of the bodys regulatory systems. The research data showed an increase in SDNN, RMSSD, a decrease in LF/HF wave power, and a decrease in the centralization index. After the 5th breathing procedure of the heated oxygen-helium mixture, the second group showed an increase in external respiration function by an average of 16%, and after a full course, by 20%, which indicates an improvement in pulmonary ventilation and a decrease in the degree of obstructive disorders.
 The use of heated oxygen-helium mixture is a promising method that does not give complications, can reduce the severity of obstructive syndrome, helps to restore the bodys adaptive systems, and can be used as one of the methods in the comprehensive rehabilitation of patients with chronic obstructive bronchitis.
