Abstracts

Objective: This study compared the estimated continuous cardiac output (esCCO) system and an arterial pressure-based CO (APCO) system. The goal of this study was to evaluate the dynamic trend of the esCCO calibrated with an invasive and non-invasive method. Methods: We retrospectively identified 12 cases with complete data for the two calibration methods. Two calibration methods were analysed and compared with APCO using polar plots. Results: Polar plotting revealed that the mean angular bias was 10.0°, and the radial limit of agreement was 37.1° when calibrated with the invasive method, while the mean angular bias was 3.5°, and the radial limit of agreement was 28.3° with the non-invasive method. Conclusion: This study suggested that the accuracy of a dynamic trend of esCCO may not be affected by the calibration methods, and the esCCO measurement by the non-invasive calibration method may be an effective device similar to that by the invasive calibration method.
