Functional Features of External Respiration in School Children of Adolescence, Long Suffering from Chronic Obstructive Bronchitis

Abstract

Context: In the modern world, chronic bronchitis is one of the most common diseases in childhood and
adolescence that can stably degrade their quality of life. In this regard, an additional examination of patients
in this category was carried out. The purpose of the work is to assess violations of the functional state of the
external respiration system in adolescents suffering from chronic obstructive bronchitis. The study involved
42 adolescents 13-14 years old, suffering from at least 5 years of chronic obstructive bronchitis of moderate
severity with no signs of respiratory failure. At the time of the examination, the disease was among the
examined adolescents in a state of unstable remission. For adolescents with chronic obstructive bronchitis,
a decrease in the vital capacity of the lungs and diameter of the bronchi of any caliber is characteristic. This
inevitably leads them to a marked decrease in the functional capabilities of the external respiration apparatus.
It became clear that early enough with this disease, the respiratory center becomes resistant to hypoxia and
weaken the adaptive capabilities of the entire external respiration system. All identified violations lead in
adolescents with chronic obstructive bronchitis to an increase in the functional weakness of their respiratory
system and circulatory system, and, therefore, form a low resistance to hypoxia even at a young age.
