Design outcomes

Primary

MeasureTime frame
To evaluate the agreement between cardiac output obtained through two different minimally invasive techniques ie by Pulse wave transit time (Nihon Kohden) and arterial pulse wave analysis (Flotrac/Vigelio)Timepoint: From iduction of anesthesia to end of surgery ie intra-operative period—

Secondary

MeasureTime frame
To evaluate changes in cardiac output with ongoing changes in mean arterial pressure.Timepoint: From iduction of anesthesia to end of surgery ie intra-operative period—
