Invasive Arterial Blood Pressure (IABP) has potential risks including bleeding and infection. Because of these risks, Non-Invasive Arterial Blood Pressure (NIBP) measurements are also widely used as an alternative. The aim of this study to compare IABP recordings with simultaneously obtained NIBP recordings in patients receiving norepinephrine (NE) and the relation with norepinephrine dosing. This observational study was conducted prospectively in 36-bed medical intensive care unit (ICU). A total of 84 patients receiving NE infusion were included in the study. Simultaneously, IABP (via brachial artery) and NIBP (using a PHILIPS® IntelliVue MX550 oscillometric monitor attached to the opposite arm with a suitable cuff) measurements were recorded hourly. Overall, 2104 pairs of IABP and NIBP measurements were obtained from 84 patients receiving NE (54 males) with mean age of 70.71 ± 14.96 and mean BMI of 26.28 ± 6.97. There were significant differences between IABP and NIBP recordings ([SBP (mean ± SD) = 112.2 ± 19.8 vs. 114 ± 19.9 mmHg; p
