Fluid Management Makes a Difference

FloPatch and Carotid Doppler Validation

FloPatch detects mild-to-moderate central hypovolemia

Journal of Trauma and Acute Care Surgery

FloPatch wearable Doppler ultrasound continuously measured the common carotid artery Doppler pulse. Carotid Doppler measures were highly sensitive at detecting both 10% and 20% stroke volume reduction and all shock indices performed well in their diagnostic ability to measure mild-to-moderate central volume loss.

Carotid Doppler accurately detects rapid hemodynamic change


Temporal concordance of 3 hemodynamic monitors was examined. Both carotid Doppler ultrasound and non-invasive pulse contour detected rapid hemodynamic change with equal accuracy. Bioreactance lagged but improved over time.
