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.
采用由小的平面 Pt 圆盘感测区域（直径=25 μm）组成的电流型氧微传感器，分析了左手腕前侧的部分氧分压（pO(2)）分布。pO(2)水平随手腕皮肤的测量位置而变化，并且在对腕部区域的一维单线（沿腕部横向折痕）和二维正方形区域的分析中系统地进行了监测。在与穴位位置接近的特定区域观察到相对较高的 pO(2)值，具有统计学意义，表明氧与穴位之间存在很强的关系。所使用的氧微传感器足够灵敏，可以根据位置检测 pO(2)变化。这项研究可能提供有助于理解穴位可能的生理作用的信息。
