Vascular Tone Monitoring System (VATMOS)
Value Proposition
By continuously assessing peripheral vascular tone, this piezoelectric-optical wearable ring provides real time insights into how the cardiovascular system is responding to illness or injury before changes in traditional vital signs like blood pressure occur. This sensor provides almost immediate feedback to clinicians on the physiologic response to treatment.
Competitive Advantage
VATMOS is easily portable, provides continuous hemodynamic monitoring, and predicts hypotension up to 108 minutes in advance. VATMOS also provides more relevant data to physicians, making it a better indicator of patient physiology than current devices such as pulse oximeters. VATMOS has practical applications in dialysis centers, combat situations, emergency rooms, ambulances, and eventually in a patient’s home.

In many emergency and critical care situations, having an accurate read on a patient’s autoregulatory response is vital for a successful outcome. VATMOS provides a cardiovascular vital sign for at risk patients in settings like sepsis, trauma, complex cardiovascular surgeries, and TBI. VATMOS also has practical applications in dialysis centers, combat situations, emergency rooms, ambulances, and eventually in a patient’s home.
