title: [Transcutaneous measurement of PaO2 by the "TCM 1" electrode (author's transl)].
abstract: Arterial oxygen pressures were compared with oxygen pressures measured transcutaneously with the aid of "TCM 1", an apparatus manufactured by Radiometer. At normal oxygen partial pressures the transcutaneously determined values for pO2 ran parallel with those measured intraarterially, but were on average 10.7% lower than the latter. In cases where oxygen partial pressures were above or below normal the figures did not agree. In these conditions, therefore, determinations in the arterial blood cannot be dispensed with. Halothane in concentrations of 0.3-0.5% and nitrous oxide (66%) in the inspired air did not affect the transcutaneous determination of pO2, but the method failed during surgical electrocoagulation.
