METHOD AND APPARATUS FOR TISSUE OXIMETRY
In accordance with the invention, the oxygenation of blood-profused tissue is measured by shining light into the profused tissue and analyzing the light reflected within the tissue. The light is reflected by cell walls in the tissue and is partially absorbed by hemoglobin in the blood. Since the ext...

| description | In accordance with the invention, the oxygenation of blood-profused tissue is measured by shining light into the profused tissue and analyzing the light reflected within the tissue. The light is reflected by cell walls in the tissue and is partially absorbed by hemoglobin in the blood. Since the extent of absorption is sensitive to the extent of hemoglobin oxygenation, measurement and processing of the reflected light provides a measure of the oxygenation of the blood. In one embodiment, the method is applied to measure the oxygenation of blood within the tympanic membrane (ear drum).
L'invention permet de mesurer l'oxygénation d'un tissu richement vascularisé, par l'application de lumière dans le tissu et l'analyse de la lumière réfléchie dans le tissu. La lumière est réfléchie par des parois de cellule du tissu et partiellement absorbée par l'hémoglobine du sang. L'absorption dépendant de l'oxygénation de l'hémoglobine, la mesure et le traitement de la lumière réfléchie permettent de mesurer l'oxygénation du sang. Dans un mode de réalisation, le procédé s'applique dans la membrane du tympan (tympan) pour mesurer l'oxygénation du sang. |
