The diagnosis of cardiogenic shock can sometimes be made at the bedside by observing hypotension and clinical signs of poor tissue perfusion, which include oliguria, cyanosis, cool extremities, and altered mentation These signs usually persist after attempts have been made to correct hypovolemia, arrhythmia, hypoxia, and acidosis. ** All patients with cardiogenic shock should be cared for in a facility at which right heart
