Abstract
Disclosed herein is a system, apparatus and method directed to placing a medical instrument in a vasculature of a patient body, including an optical fiber with one or more core fibers. The system can include a console having non-transitory computer-readable medium storing logic that, when executed, causes operations of providing an incident light signal to the optical fiber, receiving a reflected light signal of the incident light, wherein the reflected light signal is reflected from at least one of red blood cells or tissue within the patient body, processing the reflected light signal to determine an oxygen level within the patient body near a distal tip of the optical fiber. The method may further include determining a location of the distal tip of the optical fiber within the patient body at least based on the oxygen level.
