Abstract

1. 1. A pH microelectrode mounted on the tip of a cardiac catheter is described which enables continuous pH monitoring. 2. 2. Experimental studies in dogs demonstrate the accuracy of this in vivo pH electrode when compared to the value measured anaerobically by a conventional bench pH meter. 3. 3. Clinical observations indicate that the indwelling microelectrode is stable for at least seven hours and shows a rapid response to changes occurring during surgical procedures. 4. 4. Constant blood pH surveillance is of value in the management of low perfusion states as well as during complicated cardiovascular procedures.
