Gas exchange in pulmonary embolism (PE) remains a highly controversial matter, despite the considerable amount of studies appearing each year on this subject. Hypoxemia has been reported to be severe [1], mild [2] or even absent [3]. The actual value of the arterial-alveolar gradient of CO2 (P(a-A)O2) as a diagnostic tool in PE is still debated. The cause of hypoxemia has been ascribed to a true shunt [1, 4] or to VA/Q inhomogeneity [5]. In order to classify such a complex chapter of pathophysiology, we have separed the mechanisms responsible for gas exchange abnormalities in PE in two basic and several secondary, additional ones.
