Observational Study
Oxygen Desaturation and Persistence of Symptoms during Activities of Daily Living in Patients following Hospital Discharge for COVID-19.
COVID-19 can cause respiratory and multisystemic impairments, which lead to impaired activities of daily living (ADL). Telemonitoring after discharge from the hospital may help identify the persistence of such limitations during ADLs simulations. The aim of this study was to compare SpO2 , fatigue, and dyspnea through telemonitoring during a battery of 4 ADLs in patients following hospital discharge for COVID-19. ⋯ SpO2 was similar among the ADLs but walking triggered desaturation in a larger number of subjects. The subjects presented with mild-to-intense fatigue and dyspnea during ADLs 30 d after discharge after hospitalization for COVID-19 regardless of desaturation status, which demonstrated that the persistence of symptoms is independent of hypoxemia during exercise.
