Central Bp Measurement and Validation: The Engineer’s Point of View

The non-invasive assessment of aortic (central) pressure evolved as an emerging clinical research area over the last two decades. Several non-invasive methods and devices were developed to support these investigations. A variety of technical approaches and sites of peripheral signal acquisition have been established to non-invasively estimate aortic pressure, but interchangeability of results was limited due to the lack of standardization. To overcome this threatening situation, an ARTERY Society task force was set up to provide a consensus document with recommendations regarding appropriate protocols to assess and report the evaluation of accuracy of devices measuring aortic pressure.
