Non-Invasive Monitoring of Peripheral Artery Behavior via Wearable Sensors
This project continues the development of the Piezo Ring. The ring portably measures the vascular tone and reactivity of small blood vessels in the finger, which gauge a patient’s physiology and hypotension. Using computational methods, the ring predicts hypotension ranging from 9-108 minutes in advance. This is useful for hemodialysispatients who greatly benefit from constant blood pressure monitoring, as well as in combat and critical care situations.
The Piezo Ring is easily portable, provides continuous hemodynamic monitoring, and predicts hypotension up to 108 minutes in advance. The Piezo Ring also provides more relevant data to physicians, making it a better indicator of patient physiology than current devices such as pulse oximeters.
