Clinical experience in the application of the tissue pH electrode.
Only after placing the pH electrode through an incision could its point enter deep enough into the tissue. The storage of the pH electrode in a reference buffer considerably improved the stability of the electrode. The ECG electrode is at present the weakest link in the realization of continuous pH measurements. Improvements should be effected mainly with the ECG electrode, the electrode cable and the application instruments.
