Study on the mechanism of transcutaneous CO_2 emission (TCE), the high sensative Frewil CO_2 instrument was used to measure the correlativity between TCE, skin temperature (ST) and skin impedance(SI). The results showed that TCE and ST had positive correlation (r=0.19, P<0.01), the TCE and SI had nagetive correlation (r=-0.18, P<0.01). It illustrated that the TCE related to the local energy metabolism and vdume of tissue fluid. The other study showed that after thinning the corneum, TCE were significa...
