Risk factors for impaired respiratory function post COVID‐19: A prospective cohort study of nonhospitalized and hospitalized patients

Abstract

Reduced DL_CO was the major respiratory impairment 3-6 months following COVID-19, with hospitalization as the most important risk factor. The lack of association between impaired DL_CO and pathological physiological responses to exertion suggests that these physiological responses are not primarily related to decreased lung function.
