Polar plot analysis during the EEXPO test. Polar plot analysis for relative changes in CIStarling-24.4 (red dots) and CIStarling-8.1 (blue dots) compared to the changes in CIpulse during the EEXPO test. The radial limits of the agreement have been reported. The central exclusion zone (continuous light blue circle) removes data points, where the changes in cardiac index are small (less than 1.5%). The polar concordance at 30 degrees is 83% for Starling-8.1.1 and 71% for Starling-24.4. CIpulse: cardiac index measured by the pulse contour analysis method; CIStarling-24.4: cardiac index measured by the commercial version of the Starling device (averaging time 24 s, refresh time 4 s); CIStarling-8.1: cardiac index derived through raw data analysis of the Starling device (averaging time 8 s, refresh time one second); EEXPO: end-expiratory occlusion
