Pathophysiology of RV failure in the perioperative period

↓: decreased; PO₂: partial pressure of oxygen; ↑: increased; PCO₂: partial pressure of carbon dioxide; PVR: pulmonary vascular resistance; RV: right ventricular; LV: left ventricular.
* Ventricular interdepedence refers to the relationship between LV and RV filling and function resulting from pericardial and myocardial effects, including septal displacement.
