Daily Home Spirometry for Early Detection of Pulmonary Complications in Patients With COVID19

The aim of this preliminary study is to describe the potential decline in forced expiratory volume in 1 second (FEV1) or forced vital capacity (FVC) as measured by home spirometry in high-risk subjects infected with COVID-19. We hypothesize that the magnitude of such a decline in FEV1 and/or FVC may be associated with clinical deterioration and hospitalization. The study will ultimately inform a larger subsequent RCT that will evaluate the efficacy of home spirometry in the early detection (pre respiratory symptoms) of respiratory complications and therefore prompt early medical attention which is a key for improving outcome.
