[Continuous monitoring of pO2 by means of intravascular indwelling oxygen electrodes (author's transl)].

Two intravascular oxygen electrodes (of the International Biophysics Corporation and Roche) were tested in vitro and in long-term monitoring of arterial oxygen partial pressure in 19 patients. There were no complications. Both electrodes proved suitable for use for monitoring in an intensive-care situation. But both could still be improved by having greater stability and a shorter response time. Some of the indications for continuous monitoring of pO2 are mentioned: incipient respiratory failure, shock-lung, pulmonary oedema, and artificial ventilation. Haemorrhagic diatheses and arterial occlusive disease are contra-indications to its use.
