Functional and Radiological Assessment of the Respiratory System in Patients with Impaired Lung Diffusion Capacity in the Post-COVID Period

The objective: to evaluate functional and radiological data of the respiratory system assessment in patients with impaired lung diffusion capacity post-COVID period. Subjects Methods. Clinical, were analyzed compared divided into two groups according degree (LDC) impairment measured by carbon monoxide (Dlco) after 180 (135–196) days from onset acute symptoms COVID-19: Group 1 included Dlco 80–60%, 2 less than 60%. functions assessed spirometry, body plethysmography level measurement. CT scans performed period COVID-19, 93 (89–103) analyzed. Results. developed a severe form COVID-19 statistically significantly more often, they required high-flow oxygen therapy (HFO) stayed intensive care unit (ICU): 13/20 (65%), 11/20 (55%), 10/20 (50%) versus 8/24 (33,3%), 2/24 (8,3%) 3/24 (13,5%) 2, respectively. (%) Groups made 66 (64–71) 71 (67–73) 45 (41–53) 51(47–58), respectively ( p <0,05). Honeycombing changes lungs detected chest only – 16.7% on observation, Conclusion. A stay ICU additional support are factors indicating an unfavorable state presence irreversible tissue
