Comparison between changes in mean arterial pressure (MAP) measured with the femoral arterial catheter and the high-fidelity upper arm cuff (ΔMAPcuff). Changes in MAP less than 5 mmHg are excluded from the comparison. Red square, exclusion zone. In total, 299 measurements were taken in 103 patients (Pearson correlation coefficient, r = 0.99; P < 0.0001; 95% CI, 0.98 to 0.99). The concordance rate between the two methods was 99.7%.
