The aim of the study is to assess the indicators of respiratory function (FVD) in the early
rehabilitation period in patients who have undergone COVID-19.
Material and methods of research: 281 patients with various clinical manifestations of post-covid
syndrome were under observation (main observation group). As a comparison group (CG), 20
patients were examined who had undergone COVID-19 at the same time, in which the infection
ended in full recovery. The control group consisted of 20 people who did not tolerate COVID-19
and did not suffer from diseases of the respiratory system. Patients underwent multislice computed
tomography (MSCT) of the chest organs, ultrasound examination of the lungs (USIL) and computed
pneumotachometry.
Results of the study: In the period of early rehabilitation, the patients underwent control MSCT. In
the comparison group, the relative dynamics of MSCT was significantly higher than in the patients
of the main group (p <0.001). The average score for the loss of airiness of the pulmonary
parenchyma according to ultrasound scan data was 14.70 ± 10.65 points in the main group and 7.40
± 6.54 points in the comparison group (p <0.001). In patients of the main group, the values of VC
and FEV1 were significantly lower than in representatives of the CG and the comparison group (p
<0.001 for both comparisons of both indicators). VC value strongly negatively correlated with the
volume of pulmonary parenchyma lesions according to MSCT (r = -0.84, p <0.01) and USIL (r = -
0.76, p <0.01).
Conclusion: In patients with postcovid syndrome, according to spirometry data, various disorders of
the external respiration function are found in 84.70%. The degree of functional impairment of the
lungs depended on the area of damage to the lung tissue. The value of VC, reflecting the severity of
restriction, strongly negatively correlated with the volume of the lesion of the pulmonary
parenchyma according to MSCT USIL data.
