Why the study?
Does noninvasive estimation of aortic systolic blood pressure using commercial devices accurately reflect invasive measurement in study participants?
Does noninvasive estimation of aortic systolic blood pressure using commercial devices accurately reflect invasive measurement in study participants?
Automated recording of waveforms calibrated noninvasively by brachial mean arterial pressure/DBP provides relatively accurate noninvasive estimation of aortic systolic blood pressure, though overall devices underestimate it by 4.49 mmHg.

Noninvasive devices underestimate a-SBP by ~4.5 mmHg; supports MAP/DBP calibration for improved accuracy in clinical use and future validations.
