Abstract

Aim. To study the characteristics of resistance/sensitivity to normobaric hypoxia in 50 children with bronchial asthma (BA) from 9 to 12 years old, 24 of them after a previous coronavirus infection СOVID-19. Materials and methods. A normobaric hypoxic test (HT) was carried out by creating hypoxemia (threshold level SpO2 80%) during mask inhalation of a gas mixture with 1011% O2 by a child using a ReOxy Cardio apparatus (Ai Mediq S.A., Luxembourg). The data obtained were compared with the results in a group of healthy children the same age. Results. It was found that the integral level of hypoxic resistance of children with BA was generally lower in comparison with the group of healthy children, which was manifested in lower values of the hypoxic index (3.11.4, in the group of healthy children 4.92.8, p=0.005), a significantly increased level of tachycardia and a hypotonic response to dosed hypoxia. Conclusion. When typing reactions to HT, it was found that in children with BA, the type of low resistance to hypoxia is more common (to a greater extent in children with BA after a coronavirus infection), which confirms the need to involve such children in comprehensive rehabilitation programs.
