Purpose Early recognition of shock improves neurologic outcomes and survival in prematurity. Perfusion index [PI] trend displayed on pulse oxymeter signal, initially detected with signal extraction technology (SET) is a reliable noninvasive indicator of perfusion, comparable to near-infrared spectroscopy, and correlating with SVC flow (De Felice, Takahashi). PI has been used to study early neonatal outcomes with a high predictive accuracy for severe illness. In adults, routine use of …
