Heterogeneity of Skin Surface Oxygen Level of Wrist in Relation to Acupuncture Point
Figure 3
(a) A representative pO2 measurement along the wrist transverse crease as shown in Figure 1(a). The pO2 values were measured continuously at 15 different points with the one-dimensional sensor movement. Note that time increases to the left direction in axis, since the measurement was carried out with the sensor movement from point no. 15 to point no. 1. The scattered symbols representing the pO2 values measured at corresponding points are overlaid for clear presentation. (b) Averaged pO2 levels () for 15 different points. The sensor’s measurements at each point were averaged across five subjects. A paired t-test with a Bonferroni correction was conducted for six representative points (nos. 4, 6, 8, 10, 14, and 15), and the values are summarized in Table 1.
