Bottom Line: Relatively higher pO(2) values are observed at certain area in close proximity to the position of acupuncture points with statistical significance, indicating strong relationship between oxygen and acupuncture point.The used oxygen microsensor is sensitive enough to detect the pO(2) variation depending on the location.This study may provide information helpful to understand possible physiological roles of the acupuncture points.

ABSTRACT
The distribution of partial oxygen pressure (pO(2)) is analyzed for the anterior aspect of the left wrist with an amperometric oxygen microsensor composed of a small planar Pt disk-sensing area (diameter = 25 μm). The pO(2) levels vary depending on the measurement location over the wrist skin, and they are systematically monitored in the analysis for both one-dimensional single line (along the wrist transverse crease) and two-dimensional square area of the wrist region. Relatively higher pO(2) values are observed at certain area in close proximity to the position of acupuncture points with statistical significance, indicating strong relationship between oxygen and acupuncture point. The used oxygen microsensor is sensitive enough to detect the pO(2) variation depending on the location. This study may provide information helpful to understand possible physiological roles of the acupuncture points.

Schematic illustration for the points on the wrist skin where an oxygen microsensor was positioned for pO2 analysis: (a) one-dimensional and (b) two-dimensional measurement. The points, No. 1, 15 in (a) and the points, No. 1, 5 in (b) were positioned 5 mm apart from the left and right sides of the wrist. Symbol, //, represents the same separation.

The points, No. 1, 15 in (a) and the points, No. 1, 5 in (b) were positioned 5 mm apart from the left and right sides of the wrist. Symbol, //, represents the same separation.

Mentions: The measurements of pO2 levels were performed for (1) one-dimensional single line and (2) two-dimensional square area within the wrist independently. For the one-dimensional experiment, the sensor currents responding to pO2 levels were measured at 15 different points along the lateral line on the anterior aspect of the left hand-wrist transverse crease. The 15 points were evenly distributed with the same separation (d = 3–3.5 mm depending on individual subject) between two adjacent points along the transverse wrist crease line. The first point and the last 15th point were positioned 5 mm apart from the left and right sides of the wrist as shown in Figure 1(a).
