Arterial waveform analysis for the anesthesiologist: past, present, and future concepts.

abstract：BACKGROUND:The intrathoracic blood volume index (ITBVI) and central venous pressure (CVP) are routinely used to predict fluid responsiveness in critically ill patients with acute circulatory failure (systolic blood pressure < 90 mm Hg or vasopressor requirement). However, they have never been compared. METHODS:In this...
