Key result
The CNAP2GO continuous noninvasive blood pressure measurement device showed a mean difference of -1.0 mmHg (95% limits of agreement -14.8 to 12.7 mmHg) compared to invasive arterial catheter measurements.
Why the study?
Current wearable methods analyzing time components lack clinical accuracy, whereas existing technologies for direct continuous blood pressure measurement are too bulky.
Does the CNAP2GO continuous noninvasive blood pressure monitor accurately measure mean blood pressure compared to an invasive arterial catheter in surgical patients?

Does the CNAP2GO continuous noninvasive blood pressure monitor accurately measure mean blood pressure compared to an invasive arterial catheter in surgical patients?
Mean Difference: -1 (95% CI -14.8–12.7)
The CNAP2GO device provides continuous noninvasive blood pressure monitoring with clinically acceptable accuracy compared to invasive arterial lines, demonstrating feasibility for miniaturized wearable applications.
Fortin et al. (2021) conducted an observational in Patients undergoing neurosurgery with general anesthesia (n=46). CNAP2GO continuous noninvasive blood pressure measurement vs. Invasive radial arterial catheter was evaluated on Mean blood pressure (mBP) agreement (MD -1.0 mmHg, 95% CI -14.8 to 12.7). The CNAP2GO continuous noninvasive blood pressure measurement device showed a mean difference of -1.0 mmHg (95% limits of agreement -14.8 to 12.7 mmHg) compared to invasive arterial catheter measurements.
