Table 1 Examples of Doppler indices proposed to semi-quantitatively predict left ventricular filling pressures in patients hospitalized in the intensive care unit or in the perioperative course of cardiac surgery, and in patient with atrial fibrillation (adapted from [7])
From: Critical care ultrasonography in acute respiratory failure
