The Validation of Cardiac Index and Stroke-Volume Variation Measured by the Pulse-Wave Transit Time-Analysis Versus Conventional Pulse-Contour Analysis After Off-Pump Coronary Artery Bypass Grafting: Observational Study
Authors' conclusion
The overall performance of CIesCCO and esSVV versus CIPCA and SVVPCA is not clinically acceptable.
