Artifactual Hypotension Secondary to Intraoperative Transducer Failure

Department of Anesthesiology, Division of Cardiothoracic Anesthesia, Emory University School of Medicine, Atlanta, Georgia.

Abstract

Increasingly sophisticated electronic equipment now allows for direct continuous intraoperative monitoring of arterial, central venous, and pulmonary arterial pressures. Complex pharmacologic maneuvers depend on the accuracy of these measurements, which is often taken for granted (1). A direct pressure measurement system consists of a mechanical coupling device (cannula, tubing), transducer, amplifier, and display unit (2). However, the characteristics of such measuring systems are complex and those in current clinical use are imperfect at best. Overreliance on their data can be dangerous and may lead to errors in patient management. The following case report illustrates this point.
