Key messages

• The right ventricle possesses significant independent systolic function.

• Right ventricular dysfunction is common in the intensive care unit and adversely affects prognosis, cannot be inferred from left ventricular function, and requires specific management.

• Right ventricular assessment should include baseline assessment (history, examination, ECG), assessment of performance (right ventricular volumes, stroke volume, ejection fraction), and assessment of function (load-independent measures).

• Appropriate use of echocardiography and a pulmonary artery flotation thermodilution catheter allows rapid repeatable measurement of cardiac volumes, ejection fraction, pressures, loading conditions, and output, as well as construction of a right ventricular end-systolic pressure-volume graph.
