New vital sign proposed to predict hemorrhage


Researchers develop easy to use, portable and inexpensive device to predict hypovolemia from hemorrhage by noninvasive monitoring of vascular tone

ORLANDO, Fla. — Vascular tone, measured with a noninvasive, peripherally placed device, was proposed as a new vital sign to predict hemorrhage at the American Heart Association’s Scientific Sessions 2015.

Researchers from the University of Michigan developed a device, which can be placed on a patient’s finger, to continuously monitor vascular tone. An abstract presented by Sardar Ansari, PhD at the Resuscitation Science Symposium, described an animal study using the portable polyvinylidene fluoride-based sensor to detect hemorrhage.
