Body position and oxygenation: An intriguing relationship

Dyspnea and hypoxemia are among the most common symptoms and signs that need to be assessed in clinical practice.This case illustrates how simple steps in history taking and physical examination can be crucial for diagnosis.We present a patient with intermittent hypoxemia, initially attributed to a...
