Abstract

Pulse wave analysis of central aortic pressure waveform (CAP) provides additional information compared to brachial artery site, allowing a detailed follow-up of pathologies such as hypertension, coronary artery disease and diabetes. A wireless, portable and ergonomic device (uFISIO) was designed to perform morphological evaluations of carotid artery pressure (APCar), which is closely linked to CAP behavior. APCar waveform was acquired by theapplanation tonometrytechnique, and sent to a hub node of a local wireless network, in order to be processed in a mobile device. The results wereposteriorly transmitted to a central server, in virtue of the ‘Internet of Things’(IoT) concept. 3D printing technology was also used to develop the design. The device was tested in 6 young individuals, where APCar morphological parameters such as form factor, augmentation index, characteristic times and temporal integrals were assessed by the mobile application. Waveforms were acquired, transmitted, processed and stored adequately, obtaining values ​​in agreement with previous publications. The device showed versatility and comfortability in its use for APCar evaluation, as well as for the management of the resulting information. Future studies are required to determine its clinical applicability, especially in different age groups.
