1. An electrode device capable of simultaneously measuring pH and PCO2 comprising:

  • (a) means defining a pH sensor, said pH sensor comprising a hydrogen ion and carbon dioxide gas permeable membrane in contact with a hydrogen ion responsive fluid, said fluid capable of being placed in contact with a means for measuring the voltage signal from the pH sensor;

    (b) means defining a PCO2 sensor, said PCO2 sensor comprising a hydrogen ion and carbon dioxide permeable membrane having the same composition as the membrane in (a) in contact with a carbon dioxide responsive fluid, said fluid capable of being placed in contact with a means for measuring the voltage signal from the PCO2 sensor; and

    (c) wherein the means defining the pH sensor and the means defining the PCO2 sensor are connected to each other.
