FloPatch and Carotid Doppler Validation

FloPatch detects moderate-to-severe central hypovolemia

JACEP Open

In a human model of hemorrhage and resuscitation, measures from a wearable Doppler ultrasound patch correlated strongly with SV and identified moderate-to-severe central hypovolemia with excellent diagnostic accuracy.

Mayo Clinic study quantifies cardiac cycles needed to detect hemodynamic change

Critical Care Explorations

In an analysis of 18,000 cardiac cycles, this study at the Mayo Clinic determined that at least 6 cardiac cycles should be averaged before and after an intervention to adequately use carotid artery flow as a functional hemodynamic measure.
