Spectros is a leader in noninvasive sensing and remote monitoring. Our innovative biomedical optics, with groundbreaking use of white LEDs in small, noninvasive sensors, give us a history of developing devices that improve the outcome of people through non-invasive monitoring. Our largest amount of data collection and analyzing is done post operatively on free tissue flaps. VLS tissue oximetry is used for detection of ischemia in tissue. Used in Microsurgery, Endoscopy and Critical Care. T-Stat provides a novel way to non-invasively detect Sto2 - that correlates closely to SVo2. Localized measures may be taken with a selection of fiber optic sensors, or a systemic reading may be taken on the inside of the cheek, the buccal mucosa.
