Abstract
The Nexfin HD monitor (BMEYE, Amsterdam, The Netherlands; http://www.bmeye.com), is a device that measures cardiac output (CO) continuously by an inflatable finger cuff, which is the only interface with the patient. The Nexfin HD measures continuous CO by combining continuous blood pressure (BP) monitoring and a novel pulse contour method (Nexfin CO-Trek) based on the systolic pressure area and a physiological three-element Windkessel model individualised for each patient. The parameters that are measured by the Nexfin HD include continuous BP (systolic, diastolic, mean), heart rate, continuous cardiac output (CCO), stroke volume (SV), systemic vascular resistance (SVR) and an index of left ventricular contractility (dp/dt).
