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.

Mentions: Figure 4 is the color-coded contour plots of a typical two-dimensional oxygen measurement for one subject. For these contour plots, a linear change in pO2 was assumed between two adjacent points. As in the one-dimensional experiment, the pO2 values were varied depending on the locations, showing the heterogeneity of skin oxygen levels. The acupuncture point-high pO2 relationship is observed more clearly in the two-dimensional analysis. According to Eastern medicine, there are eight acupuncture points known in the wrist region for which the oxygen measurements were carried out: LU9 (Taiyuan) and LU8 (Jingqu) on the lung meridian; PC7 (Daling) and PC6 (Neiguan) on the pericardium meridian; and HT7 (Shenmen), HT6 (Yinxi), HT5 (Tongli), and HT4 (Lingdao) on the heart meridian. The locations of these acupuncture points are indicated in Figure 4(a). In fact, the pO2,norm⁡ values are greater than 1 (i.e., higher pO2 level than the average) at the points close to the area where these acupuncture points are supposed to be present. Another typical example is shown in Figure 5. In this example, heterogeneous pO2 distribution over the wrist is also observed, obviously showing the strong correlation between the acupuncture point and high pO2 level. Similar pO2 distribution patterns were observed for overall five subjects.
