[The oxymeter, a new device for the continuous transcutaneous measurement of the arterial oxygen partial pressure].

The transcutaneous measurement of the arterial pO2 is a practicable method for routine clinical use. The covering, calibration and fixation of the electrode are simple. In normal circulatory states the correlation between arterial and transcutaneous pO2 is high. The stability of the electrode permits its use even for long term monitoring. Recalibration is necessary at intervals of 12 h. Orientating blood gas analysis for control is nevertheless essential. After a measuring period of 5--6 h a blistering under the electrode is possible. The placement of the electrode has to be changed after 4 h. The continuous measurement opens new possibilities for the therapy, diagnosis and trend analysis.
