1. A medical instrument system for determining an oxygen level within a patient body, the system comprising:
a medical instrument comprising an optical fiber having one or more core fibers; and
a console including one or more processors and a non-transitory computer-readable medium having stored thereon logic which, when executed by the one or more processors, is configured to cause operations including:
providing an incident light signal to the optical fiber,
receiving a reflected light signal of the incident light signal, wherein the reflected light signal is reflected from one or more of red blood cells or tissue within the patient body,
processing the reflected light signal to determine the oxygen level within the patient body near a distal tip of the optical fiber, and
determining a location of the distal tip of the optical fiber within the patient body based on the oxygen level and an entry site of the medical instrument.
