Fig 2. Illustration of invasive blood pressure (IBP) readings (approximately one hour before and one hour after the non-invasive blood pressure (NBP) reading considered for analysis) as it was used to screen IBP tracks for potential artifacts or inconsistency.

Since the changes in this example were more than 10 mmHg in particular after the IBP under consideration (marked with black circles), the pair corresponding to this IBP reading was excluded from analysis. Note that the NBP reading was not visualized in the figure in order to blind selection/exclusion of IBP readings.
