This exploratory study will assess noninvasive pulse waveform acquisition using an ultrasound sensor system under development in healthy adults. At the radial artery, two-site PWV will be assessed at rest, during leg elevation, and during deep breathing, and compared with changes in systolic blood pressure. At rest, waveforms from both common carotid arteries will be acquired and compared.
Efficacy
Success rate of pulse waveform acquisition. For the radial artery, separate and simultaneous two-site acquisition will be evaluated at rest, after lower limb elevation, and after deep breathing. For the common carotid arteries, separate left- and right-side and bilateral acquisition will be evaluated at rest. Successful acquisition is defined as clear identification of the pulse upstroke and main peak without interference from signal saturation or motion artifacts.
Waveform acquisition stability; success rate of radial artery PWV calculation; directional agreement and correlation of changes between systolic blood pressure and PWV; and comparison of the morphological and temporal characteristics of the left and right common carotid artery waveforms at rest.
