Detecting Ischemic Danger at the Source

Abstract

Using near-infrared spectroscopy, the INVOS (In-Vivo Optical Spectroscopy) System provides real-time, site-specific cerebral/somatic measurements of de-oxygenated and oxygenated hemoglobin molecules within red blood cells through a noninvasive oximeter. Perioperative professionals can use the vital sign information monitored by this technology to detect and correct site-specific blood oxygenation issues that can lead to complications and poor outcomes.

Expansion volémique ou noradrénaline : que choisir ?

“…Il est possible que des durées cumulées d'hTPA soient interprétées comme un signal de danger à travers l'hypoxie tissulaire [19] mettant en jeu de multiples mécanismes compensateurs dont l'activation du système nerveux sympathique et la réaction inflammatoire avec des conséquences délétères. Les variations (hypo-et hypertension artérielle) de la pression artérielle, même relativement mineures, pourraient représenter des successions d'épisodes d'ischémie-reperfusion [2,20].…”

Innovative and Technologically Savvy

“…In September 2009, the AORN Journal introduced a new column called AORN Innovation Zone. The column, written by Carina Stanton, AORN senior news editor, discusses a system for measuring cerebral oxygen levels during surgery 1 . This topic has received widespread attention as an important component of patient safety; consequently, cerebral oximetry is increasingly employed during surgical procedures.…”
