چکیده
Abstract Introduction The novel coronavirus SARS-Cov-2 can infect the respiratory tract causing a spectrum of disease varying from mild to fatal pneumonia, and known as COVID-19. Ongoing clinical research is assessing potential for long-term sequelae in these patients. We assessed function cohort patients after recovering infection, stratified according PaO 2 /FiO (p/F) values. Method Approximately one month hospital discharge, 86 COVID-19 underwent physical examination, arterial blood gas (ABG) analysis, pulmonary tests (PFTs), six-minute walk test (6MWT). Patients were also asked quantify severity dyspnoea cough before, during, hospitalization using visual analogic scale (VAS). Seventy-six subjects with ABG during three groups their worst p/F values: above 300 (n = 38), between 200 30) below 20). Results On PFTs, lung volumes overall preserved yet, mean percent predicted residual volume was slightly reduced (74.8 ± 18.1%). Percent diffusing capacity carbon monoxide (DLCO) mildly (77.2 16.5%). reported breathlessness at time visit (VAS 19.8, p < 0.001). had lower forced vital (p 0.005), total 0.012), DLCO 0.001) shorter 6MWT distance 0.004) than higher p/F. Conclusion have impairment, including exercise tolerance. extent this impairment seems correlate failure hospitalization.

Coronaviruses (CoVs) are a group of viruses that induce infection in the respiratory and other systems in the human body. There are two coronaviruses that transmitted from animals to humans including severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS) (1). The novel coronavirus that appeared at first in Wuhan, China, in December 2019 was named as severe acut...
