Bland-Altman analysis between ABP measurement (SAP and MAP) on invasive (radial artery, Kt) and non-invasive (Nexfin) devices divided into three sub-groups according to norepinephrine infusion rate: < 0.2 mg/h (black circle), from 0.2 to 0.5 mg/h (red circle) and > 0.5 mg/h (green circle). Black, red and green dashed lines representing mean bias respectively in each n sub-group: according to norepinephrine infusion rate: < 0.2 mg/h, from 0.2 to 0.5 mg/h and > 0.5 mg/h. A Accuracy and precision for SAP measures between Nexfin device and Kt in each sub-group. B Accuracy and precision for SAP measures between intermittent Arm Cuff and Kt in each sub-group. MAP, mean arterial pressure; SAP, systolic arterial pressure
