Abstract

A novel electrooptical method using near infrared light is proposed to provide a noninvasive and continuous means of assessing the brain oxygenation. An animal model is developed for future diagnostic application in humans. The method was evaluated during acute cerebral ischemia and hypoxia. The near infrared light response to the brain pathological conditions was expressed in terms of relative absorption (RA). The overall RA response to ischemia was much faster than during hypoxia. The fairly different patterns can serve as a warning signal of a low level of oxygen supply to the brain and can also help discriminate the causes of the reduced brain oxygenation.
