Claims

1-32. -32. (canceled)

33. A method for measuring blood oxygen saturation in a blood-filled structure comprising:

a) providing a subject;

b) providing a system comprising;

1) at least one oximeter sensor comprising;

i) at least two light sources of differing wavelength;

ii) at least one photodetector; and

iii) a sensor housing comprising;

a′

) a flexible tubular member;

b′

) an optically transparent electrically isolated sheath; and

c′

) a cable comprising at least one connector; and

3) a processor comprising;

i) a controller;

ii) an oxygen saturation program on a computer-readable medium for analyzing a plurality of signals from said oximeter sensor configured to generate a distribution of the relative frequency of occurrence of oxygen saturations obtained within defined intervals of oxygen saturation at a plurality of predetermined averaging intervals;

iii) a database; and

iv) a display; and

c) positioning said oximeter sensor in a position adjacent to a blood-filled structure of said subject wherein said display of said distribution identifies said blood-filled structure; and

d) measuring said blood oxygen saturation in said blood filled structure of said subject.
