Kaur B, et al. - Using comparative analytical design and including 36 adult patients receiving inotropes, researchers performed this study in the intensive care unit of a tertiary care center in order to compare invasive and noninvasive monitoring of blood pressure (BP). Every 30 minutes, they recorded systolic and diastolic BPs simultaneously using invasive (radial arterial cannula) and noninvasive (Philips Intellivue MP-60 oscillometric monitor attached to the opposite arm) methods. They used Bland–Altman analysis to evaluate statistical analysis Agreement (precision) between both the methods. More than 10 mmHg difference was considered to be clinically unacceptable. They reported a difference of 2.3±16.9 and 0.7±10.6 mmHg for systolic and diastolic BP levels, respectively. In this patient population, the non-reliability of noninvasive BP measurement using an oscilllometric monitor (Philips Intellivue MP-60) was shown as an alternative to invasive intra-arterial measurement.
