Abstract

The standard MDO multiwire surface oxygen electrode was redesigned to enable measurements across transition zones between normal and, e.g., ischemic tissues. The eight measuring points were arranged in an array 2.2 mm long. This array multiwire electrode (AME) has been tested and showed the same electrochemical properties as the standard MDO electrode. The resolving power was tested and an individual measuring point was affected by a change in surrounding pO2 if it occurred within a distance of 20 microns. In experiments in the pig heart subjected to local ischemia it was found that both ischemic and normal tissue oxygen pressure were registered simultaneously by the AME.

摘要

标准的MDO多丝表面氧电极经过重新设计，以便能够在正常组织与例如缺血组织之间的过渡区域进行测量。八个测量点排列成一个2.2毫米长的阵列。这种阵列式多丝电极（AME）已经经过测试，显示出与标准MDO电极相同的电化学特性。对其分辨能力进行了测试，如果周围的氧分压在20微米的距离内发生变化，单个测量点就会受到影响。在对猪心脏进行局部缺血的实验中发现，AME能够同时记录缺血组织和正常组织的氧分压。
