Validation of noninvasive continuous arterial pressure measurement by ClearSight System™ during induction of anesthesia for cardiovascular surgery

Tanioku et al. (2020) conducted an observational in Elective cardiovascular surgery (n=18). ClearSight System noninvasive arterial pressure measurement vs. Invasive radial arterial pressure measurement was evaluated on Bias and precision between noninvasive and invasive mean arterial pressure (bias -3.9 mmHg (precision 7.8 mmHg)). Mean arterial pressure measured by the ClearSight System showed a bias of -3.9 mmHg and precision of 7.8 mmHg compared to invasive radial arterial pressure, meeting AAMI criteria for acceptable agreement.
