Abstract: An electrode assemblyfortranscutaneously measuring a blood gas parameter and for measuring a bioelectrical signal comprises two separate electrode devices (10, 40), one of which (10) further comprises an electrochemical measuring electrode system. The electrochemical measuring electrode system comprises a reference electrode of a potentiometric electrode system and an anode of a polarographic electrode system constituted by a single metallic body (13), a pH-electrode (31,32) of the potentiometric electrode system, and a noble metal cathode (33 34) of the polarographic electrode system. The biolectrical signal sensing electrode of the electrode device (10) is further constituted by the metallic body (13). A first part of the metallic body (13) is covered by an electrolyte solution (28) which communicates electrolytically therewith and further with the pH-glass electrode and the noble metal cathode, and a second part of which is not covered by the electrolyte solution but adapted to electrically conductively communicate with a skin surface part of a test person or a patient through an electrically conductive contact liquid (19). The membrane separates the first and the second part of the metallic body from one another. The second electrode (40) comprises a bioelectrical signal sensing electrode (41), which is adapted to electrically conductively communicate with a skin surface part of a test person or patient through an electrically conductive contact liquid (20). By means of the electrode assembly coincident measuring results of the blood gas partial pressures of oxygen and carbon dioxide and of a bioelectrical signal such as the ECG (Electrocardiography), the RR (Respiration rate) or the heart rate of the test person or patient is obtainable (Fig. 3).
