Traditional PCO2 electrode

The Severinghaus electrode directly measures CO2 tensions by allowing the CO2 gas to undergo a chemical reaction that produces hydrogen ions. Since the amount of CO2 that diffuses across the permeable membrane is directly proportional to the pressure gradient, the hydrogen ion production will create a proportional difference in potential that is measured by half-cells similar to those of the pH electrode. Both the reference and measuring half-cells of the PCO2 electrode are silver/silver chloride. The pH-sensitive glass is separated from the blood sample by a silicon elastic membrane and by a nylon spacer saturated with a bicarbonate solution which constantly replenishes the solution at the electrode tip and spacer.
