A multiwire surface oxygen pressure electrode for measurement across zones of normal and damaged tissue

H Walfridsson et al. Int J Clin Monit Comput. 1985.

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.
