1. A method comprising:
providing a probe tip of an oximeter probe comprising a source structure and a detector structure;
providing a marking mechanism output, coupled to the probe tip of the oximeter probe;
transmitting a first light through the source structure of the probe tip into a target tissue, wherein the marking mechanism output does not obstruct the transmitting of the first light through the source structure into the target tissue;
receiving a second light transmitted through the target tissue at the detector structure of the probe tip, wherein the marking mechanism output does not obstruct the receiving of the second light through the detector structure from the target tissue;
based on values for the first and second light, determining an oxygen saturation value for the target tissue; and
after the determining an oxygen saturation value, using the marking mechanism output to mark or not mark a tissue surface representative of the oxygen saturation value.
