We are exploring the application of optical spectroscopy for the noninvasive measurement of blood and tissue chemistry, ultimately to be able to perform chemical analysis and diagnosis without removing a sample from the patient. We are currently investigating the use of near infrared spectroscopy in combination with in-vivo chemometric techniques to determine tissue pH, tissue oxygen tension and blood hematocrit. We are also interested in the application of this technology in the triage and treatment of trauma patients.
