Key result
Continuous noninvasive blood pressure monitoring by TL-300 demonstrated high accuracy compared to invasive measurement, with a mean BP bias of 1.8 mm Hg (95% limits of agreement -6.4 to +10.1 mm Hg).

Does continuous noninvasive blood pressure monitoring by TL-300 provide accurate and precise measurements compared to standard invasive blood pressure measurement in patients undergoing elective neurosurgery?
Mean Difference: 1.8 (95% CI -6.4–10.1)
The TL-300 system is a promising noninvasive alternative to invasive arterial catheters for intraoperative blood pressure monitoring, demonstrating high accuracy and precision.
Lin et al. (2015) conducted an observational in Elective neurosurgery (n=23). Continuous noninvasive blood pressure monitoring by TL-300 vs. Standard invasive radial arterial catheter method was evaluated on Accuracy and precision of continuous BP monitoring (mean BP) (Bias 1.8 mm Hg, 95% CI -6.4 to 10.1). Continuous noninvasive blood pressure monitoring by TL-300 demonstrated high accuracy compared to invasive measurement, with a mean BP bias of 1.8 mm Hg (95% limits of agreement -6.4 to +10.1 mm Hg).
