1 myoglobin oxygen saturation of muscle tissue. (col. 3, ll.
2 36-38 and 41).
3 11. Arakaki uses a probe having separated illumination fibers in
4 useful reflectance measurements to assure that a discrete
5 minimal optical path length through tissue is obtained. The
6 reference refers to an article that suggests the source to
7 detector separation being roughly twice the average depth of
8 penetration of light into tissue, and that setting the spacing
9 between the two sets of fibers to about 1-3 mm is expected
10 to have an average penetration of about 0.5 mm to about 1.5
11 mm. (col. 8, lines 5-20).
12 12. Aranow is directed to using light, emitted through a patient's
13 finger tip, ear, etc. for use in analyzing a person's blood.
14 The detected light is amplified and used to determine a
15 patient's pulse and oxygen saturation level, and/or
16 oxyhemoglobin, etc. (col. 2, l. 60 to col. 3, l. 8).
17 13. Aranow discloses that in the event that a monitored
18 characteristic goes above/below predetermined threshold
19 values, an audio alarm may sound to alert attending medical
20 personnel. (col. 5, lines 48-57).
21 14. Mendelson indicates that his invention is directed to the
22 accurate measurement of blood analysis based on the
23 principle of transmission and reflection
24 photoplethysmography. Glucose is measured by analyzing
25 the difference or ratio of two different near infrared
