New preprint on cuffless blood pressure with speckle contrast optical spectroscopy
Today we’re sharing our new bioRxiv preprint on cuffless blood pressure measurements using high-speed speckle contrast optical spectroscopy (SCOS). We show that measurements of pulsatile blood flow with SCOS can substantially improve blood pressure estimates above what’s available with photoplethysmography (PPG). We believe this opens the door to continuous ambulatory blood pressure without a cuff, as well as the potential for more general personal health monitoring.
This project has been in the works for several years, and started as a collaboration between my Lab, David Boas and his lab, and Meta, including Nil Gurel and Edbert Sie among others. Ariane Garrett and Byungchan (Kenny) Kim are the talented Ph.D. students pushing this work forward.
