Post-covid State of External Respiratory Function in Hospitalized and Outpatient Patients

A one-time medical and biological examination of the health status of 161 residents of Yakutsk aged 20 to 72 years who recovered from COVID-19 3-12 months ago during the first wave of the pandemic was carried out. Changes in lung function were detected in 29.5% of 139 patients who underwent spirometry. Among them, 7.2% of the surveyed revealed extremely severe changes. The appearance of symptoms and disturbances in the function of external respiration in the post-covid period did not have significant differences in hospitalized and outpatients, and were not associated with the post-covid period, the severity of lung damage in the acute period of the disease, smoking, and the presence of chronic diseases of the respiratory system. The obstructive and restrictive type of disorder was more often observed in women treated on an outpatient basis, which indicates a protracted recovery that requires the same rehabilitation measures that are carried out for hospitalized patients in order to eliminate multiple organ post-COVID complications.
