Carotid Artery Corrected Flow Time Measured by Wearable Doppler Ultrasound Detects Stroke Volume Change Measured by Transesophageal Echocardiography After Coronary Artery Bypass GraftingTake-Home Points

Background: As a measure of preload responsiveness (PR), change in carotid artery corrected flow time (ccFTΔ) is a surrogate for change in stroke volume (SVΔ). However, the optimal threshold and accuracy of ccFTΔ to detect SVΔ are inconsistent in previous reports. Research Question: Does ccFTΔ from...
