Abstract:
1. A near infrared spectrophotometric (NIRS) sensor assembly for non-invasive monitoring of blood oxygenation levels in a subject's body tissue, said assembly comprising: a flexible pad; at least one light source operative to emit near infrared light signals of a plurality of different wavelengths; a first light detector operative to measure light intensity values derived from light emitted by the light source and passing through the subject's body tissue, wherein the first light detector is separated from the light source by a first distance of about 15 mm; and a second light detector operative to measure light intensity values derived from light emitted by the light source and passing through the subject's body tissue, wherein the second light detector is substantially linearly aligned with the first light detector and the light source, and is separated from the light source by a distance in the range of about 47-50 mm, wherein the first light detector is disposed between the light source and the second light detector.
