Pulmonary Function Test: A Mainstay for Evaluating Respiratory Health in Patients Recovered from COVID-19 Infection

The pulmonary functions of the patients recovered from COVID-19 infection should be evaluated before discharge of the patient from hospital followed by periodic evaluation post discharge, so that necessary therapeutic interventions can be initiated. Breathing exercises and pranayama can augment the better outcome of these patients. Pulmonary function tests are not only recommended but also are necessary for monitoring of patients who have recovered from COVID-19 infection.
