Transcutaneous measurement of arterial blood oxygen tension with a new electrode

A new electrode for measuring the transcutaneous oxygen tension (tc-PO2) is described. The electrode has been tried out on newborn infants suffering from idiopathic respiratory distress syndrome (IRDS), and the results obtained have been compared with the arterial oxygen tension (PaO2). A fairly close agreement was found, and the least deviations were seen in the range below 250 mmHg.
