Effects of Intermittent Normobaric Hypoxia on External Respiration in Children Residing in Areas Contaminated by Radiation
ABSTRACT
The effect of intermittent normobaric hypoxia (INH) of sanogenic level was studied in children residing in areas contaminated by radiation. The study involved 106 children aged 6 to 17 years with symptoms of bronchospasm: 55 subjects in the main group and 51 − in the control group. It has been revealed that the course of INH sessions (12% oxygen in nitrogen) results in changes in the respiratory system. In particular, the parameters of lung ventilation capacity, namely vital lung capacity, airway conductance of the proximal bronchi of large and medium diameter, and distal bronchi of small diameter increase significantly in the main group. Moreover, bronchospasm is prevented either partially or completely, timed inspiratory capacity (Stange's test) extends, and the heart rate decreases compared to the control group.
