“Carotid Artery Flow Time and Peak Velocity Changes Predict Fluid Responsiveness in Mechanically Ventilated, Low Tidal Volume Patients”

https://pubmed.ncbi.nlm.nih.gov/38117132

The study found that changes in carotid artery corrected flow time and peak flow velocity in response to a fluid challenge can predict fluid responsiveness in mechanically ventilated patients with low tidal volume and preserved spontaneous breathing, with the former showing superior predictive performance.
