BackgroundPulseCO for continuous cardiac output measurement is a relatively noninvasive and effective monitor. PulseCO is obtained from the arterial pulse waveform, but calibration by another method is necessary. We performed calibration of PulseCO by CO measurement using TEE and examined the utility of PulseCO.MethodsPulseCO was calibrated by TEE after induction of anesthesia, and PulseCO and continuous cardiac output with Vigilance (CCO) were measured continuously. Records were obtained every thirty minutes and were excluded from analysis when hemodynamics was unstable.ResultsCorrelations of CCO with TEE (r = 0.88) and PulseCO (r = 0.86) were examined. PulseCO showed a significantly better correlation with CCO, and dispersion was small.ConclusionsThe results suggest that PulseCO is very useful as an intraoperative cardiac output measurement monitor.
