The technology platforms used to develop HTI's medical device products include optical metrology, and specifically, near infrared spectroscopy. Coupled with HTI's world leadership in precision engineering, these technologies provide a powerful foundation for innovation in health care.

Near Infrared Spectroscopy Near infrared spectroscopy (NIRS) uses specific, calibrated wavelengths of near infrared light to noninvasively illuminate the tissue below a sensor placed on the skin. (more)
NIRS and the InSpectra™ StO 2Tissue Oxygenation Monitor The InSpectraStO 2 Tissue Oxygenation Monitor works by sending light through the skin into underlying tissues and taking measurements of the light after it travels through the tissues. (more)		StO2: Tissue Oxygen Saturation StO2 is the quantification of the ratio of oxygenated hemoglobin to total hemoglobin in the microcirculation of the volume of illuminated tissue, and is an absolute number.

The InSpectra™ StO₂ Tissue Oxygenation Monitor provides a noninvasive, continuous, real-time, and direct measurement of hemoglobin oxygen saturation in tissue (StO₂), providing trauma teams the ability to measure tissue oxygen saturation and monitor it during resuscitation. It is the only perfusion status 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.
