Abstract
Respiratory disorders are among the most frequent conditions after COVID-19, along with increased fatigue, insomnia, depressive disorders, attention and memory disorders. The incidence of respiratory disorders after COVID-19 is on average 35%. The objective of the review is to study the characteristics and duration of functional respiratory disorders in the post-COVID period in the available literature. Many works have been devoted to the study of post сovid disorders, including the assessment of the functional state of the respiratory system using various diagnostic methods, functional tests. However, it remains unclear how long respiratory disorders persist in patients who have had COVID-19 infection, and what factors influence their dynamics.
