Polar plot showing changes in ΔCO-TTE in comparison with ΔCO-PAC. A central exclusion zone of 0.5 L/min (half circle) and ± 30° axes (solid lines) are indicated. Mean polar angle: 1.0°; 95% radial LOAs: –26.8 to 28.8° (dotted lines). Concordance rate (between –30 and 30°) was 100%. CO-PAC cardiac output measured by pulmonary artery catheter, CO-TTE cardiac output estimated by transthoracic echocardiography
