Abstract

Objectives: To study the feasibility of multicomponent non-invasive monitoring, consisting of a new bioimpedance method for estimating cardiac output together with routine pulse oximetry and transcutaneous oximetry, and to compare physiologic data obtained noninvasively with hemodynamic and oxygen transport data obtained by standard invasive pulmonary artery thermodilution catheter to evaluate circulatory function in high-risk surgical patients. Design: Prospective descriptive analysis of the time course of physiologic patterns in surgical patients. Setting: University-run county hospital. Patients: Seventy-one consecutively monitored, high-risk, critically ill surgical patients in their perioperative period. Outcome Measures: Simultaneous measurements by invasive and noninvasive methods to describe and compare the temporal physiologic patterns of survivors and nonsurvivors. Results: The new impedance cardiac output estimations closely approximated those of the thermodilution method (r=0.82, P
