example

[0195] First, a target ROI is selected, preferably a localized tissue, and more preferably, a small patch of skin, and most preferably a small patch of skin such as a forearm that is less hairy and flatter. Preferred other possible locations include cheeks, thighs, facial and maxillary regions. In alternative embodiments, the localized tissue is buccal mucosa, rectal mucosa, bladder mucosa, intraperitoneal chorion, or other tissue available for imaging. We then collect spectral data from the ROI or a portion of the ROI at a predetermined distance or at a measured or estimated or recorded distance. Preferably, the distance is less than 10 feet, and more preferably, between 6 and 36 inches, and most preferably, between 12 and 18 inches.

Abstract

The present invention provides a hyperspectral imaging system which demonstrates changes in tissue oxygen delivery, extraction and saturation during shock and resuscitation including an imaging apparatus for performing real-time or near realtime assessment and monitoring of shock, including hemorrhagic, hypovolemic, cardiogenic, neurogenic, septic or burn shock. The information provided by the hyperspectral measurement can deliver physiologic measurements that support early detection of shock and also provide information about likely outcomes.
