Pulse contour cardiac output analysis in a piglet model of severe hemorrhagic shock*

Abstract

TPTD CO and recalibrated PCCO analysis correlate well with PATD CO in this severe hemorrhagic shock model. The mean difference is small (<0.15 L/min) and is not clinically significant. With rapid changes in blood pressure or intravascular volume, PCCO is not accurate unless recalibrated by TPTD CO. SVO2 did not correlate well with CO in this model.
