FIBEROPTIC PROBE FOR MEASURING TISSUE OXYGENATION AND METHOD FOR USING SAME

摘要

Embodiments herein relate to the field of medical monitoring, and, more specifically, to a fiberoptic probe for monitoring tissue oxygenation and a method for using such a probe. A non-invasive method of measuring tissue oxygenation includes, in some embodiments, illuminating a tissue surface with a first fiberoptic fiber, receiving light from the tissue surface with a second fiberoptic fiber, measuring the absorption spectra of oxy- and deoxy-hemoglobin in the light, and calculating a tissue oxygenation value based on the absorption spectra.

主权项

1. A fiberoptic device, comprising:
a probe comprising at least a first fiberoptic fiber and a second fiberoptic fiber, wherein the first and second fiberoptic fibers terminate at or near a surface of the probe; a visible wavelength light source coupled to the first fiberoptic fiber; and a spectrometer coupled to the second fiberoptic fiber and configured to measure light transport in tissue adjacent to the surface of the probe.
