Platypnea-orthodeoxia Syndrome: An Important Cause of Morbidity in Post Coronavirus Disease Patients

Abstract

Platypnea-orthdeoxia syndrome (POS) is a clinical scenario where patient get breathless while sitting or standing. its important causes are cardiac shunts, hepatopulmonary syndrome and pulmonary ventilation perfusion mismatch. During this pandemic as cases of pulmonary fibrosis increased, we find POS as one of the important cause of morbidity during recovery. Early recognition of this will decrease the morbidity and unrealistic expectation of fast recovery.
