Editor—Inferring changes in stroke volume (SVΔ) is of clinical interest because SVΔ can both guide resuscitation and detect haemodynamic impairment, for example, cryptogenic haemorrhage. 1 Kenny J.-É.S.

A wireless ultrasound patch detects mild-to-moderate central hypovolemia during lower body negative pressure. J Trauma Acute Care Surg. 2022; 93: S35-S40 Crossref PubMed Scopus (4) Google Scholar Because assessing SVΔ typically requires invasive intravascular catheters and monitors, there is a demand for noninvasive approaches. The corrected flow time of the carotid artery (ccFT) has been used to deduce SVΔ in elective surgical and critically ill patients. A recent meta-analysis found that ccFT has excellent diagnostic accuracy for predicting fluid responsiveness (i.e. a clinically significant increase in SV or cardiac output after increased preload). 3 Singla D.
