1973年Huch等研制的皮肤氧张力表面电极具有非侵袭性的优点,只要按置于皮肤表面可以连续记录氧张力(经皮肤氧张力,tcPO_2)。由于电极中有加热装置使局部毛细血管扩张,即所谓使之动脉化,所以其所测得的数值可以代表动脉血氧张力(PaO_2),这对新生儿抢救监护更为适合。Huch电极系改良Clark电极,以15微米白金为阴极,以具有加热线圈 Skin oxygen tensile surface electrodes developed by Huch et al. In 1973 have the advantage of non-invasiveness. The oxygen tension (transcutaneous oxygen tension, tcPO_2) can be continuously recorded as long as they are placed on the skin surface. Because the electrode has a heating device to local telangiectasia, the so-called arterialization, so the measured value can represent arterial oxygen tension (PaO_2), which is more suitable for neonatal rescue monitoring. The Huch electrode is a modified Clark electrode with 15 micron white gold as the cathode to have a heating coil
