Abstract: When monitoring blood oxygen levels in a patient during a magnetic resonance scan, detachable and reusable fiber optic cable heads (16, 18, 98, 131, 132) are coupled to an SpO2 monitor and to a hinged finger clip (40, 70, 90, 110, 190) on a patient. The finger clip (40, 70, 90, 110, 190) includes apertures (94, 196) and a retaining structure (44, 95, 198) to which a coupling portion of the fiber heads (16, 18, 98, 131, 132) are releasable attached.

Abstract: The present invention relates to a method and system for estimating blood analyte levels using a noninvasive optical coherence tomography (OCT) based physiological monitor. An algorithm correlates OCT-based estimated blood analyte data with actual blood analyte data determined by other methods, such as invasively. OCT-based data is fit to the obtained blood analyte measurements to achieve the best correlation. Once the algorithm has generated sets of estimated blood analyte levels, it may refine the number of sets by applying one or more mathematical filters. The OCT-based physiological monitor can be calibrated using an Intensity Difference plot or the Pearson Product Moment Correlation method.
