The aim is to address the challenges of diagnosing and managing oxygen-refractory platypnea-orthodeoxia syndrome.
Urgent surgical intervention was employed to correct the right-to-left shunt.
Evaluation of posture-dependent hypoxemia was conducted to determine the severity of the condition.
Post-surgical assessment showed significant improvement in oxygen saturation levels.
Patient outcomes indicated resolution of posture-dependent hypoxemia.
Abstract
Platypnea-orthodeoxia syndrome (POS) causes posture-dependent hypoxemia due to right-to-left shunt, and it may be underestimated by routine evaluation.
