Peripheral Vascular Disease

The InSpectra™ StO2 Tissue Oxygenation Monitor has not been cleared by the FDA for use in diagnosing peripheral vascular disease. Additional clinical studies are required to establish the value of these measurements in assessing patient status relating to peripheral vascular disease.

A study comparing patients with peripheral arterial disease (PAD) to normal patients demonstrates the potential value of the InSpectra™ System for assessing compromised circulation.










The InSpectra™ StO2 Tissue Oxygenation Monitor provides a direct, absolute measurement of hemoglobin oxygen saturation in tissue (StO2), providing trauma teams the ability to measure tissue oxygenation and monitor it during resuscitation. It is the only tissue oxygenation monitor designed for trauma environments. The InSpectra StO2 Tissue Oxygenation Monitor uses near infrared light to illuminate tissue, and then analyzes the returned light to produce a quantitative measurement of oxygen saturation in the tissue's microcirculation.

The StO2 Trauma Study researched the role that tissue oxygen saturation monitoring could play in hemorrhagic shock and resuscitation. Study results demonstrate that StO2 measurements less than 75% may indicate serious hypoperfusion in trauma patients and that StO2 functions as well as base deficit in indicating hypoperfusion in trauma patients.
