WebDefinition ARDS is an acute pulmonary disorder characterized by diffuse capillary leak resulting in wet lung and a constellation of features secondary to it. This syndrome is associated with a multitude of clinical conditions which primarily damage the lung or secondarily as part of a systemic disorder. Pathogenesis WebA shunt can be defined as “a vascular passage by which blood is diverted from its usual or normal path (arteriovenous)(1).” Arteriovenous anastomoses (i.e., shunts) were first described 129 years ago (19) and these pathways allow for arterial blood to bypass the capillary beds and join up with postcapillary venous blood. netplwiz cmd command
