Abstract
Using conventional platinum electrode catheters, negatively polarized with reference to silver electrodes on the skin, spatial and temporal changes in the oxygen tension of the blood can be recorded. By adjusting the polarizing voltage, flow effects on the oxygen cathode can be suppressed. The method is, among other things, suitable for detecting and localizing very small left-to-right shunts.Keywords
