Abstract
Hemodynamic monitoring is central to intensive care as well as perioperative patient management. For anesthesiologists and intensivists, it is crucial to maintain adequate organ perfusion throughout the body during the time course of critical illness or surgery. Adequate organ perfusion implies (1) a perfusion pressure that is high enough to maintain capillary patency within all organs, and (2) enough flow to deliver oxygen and substrates and to remove carbon dioxide (CO2) and other metabolic by-products. But in many instances, the only aspect of perfusion that is carefully monitored is pressure, whereas flow is simply ignored. One of the reasons for this may be related to the difficulties encountered in obtaining flow measurements. Esophageal Doppler is one of the alternative devices that facilitate flow measurement by avoiding the placement of a pulmonary artery catheter.
