Reflective oximeter catheter
WebReflection pulse oximetry, in which the light sources and the photodetector are located on the same surface of the skin, can be applied on any accessible site, and is thus of advantage in low peripheral perfusion conditions. 45,46. The main site used for reflection pulse-oximetry measurement is the forehead. WebAn oximeter is described which employs two bundles of flexible glass fibers to conduct appropriately filtered light into, and that light diffusely reflected by the blood out of, the blood stream for the determination of oxygen saturation or dye concentration within blood flowing past the tip of either an arterial needle or a cardiac catheter …
