carbon dioxide electrode

car·bon di·ox·ide e·lec·trode

a glass electrode in a film of bicarbonate solution covered by a thin plastic membrane permeable to carbon dioxide but impermeable to water and electrolytes; the carbon dioxide pressure of a gas or liquid sample quickly equilibrates through the membrane and is measured in terms of the resulting pH of the bicarbonate solution, as sensed by the glass electrode; commonly used to analyze arterial blood samples for CO₂. Synonym(s): Severinghaus electrode

carbon dioxide electrode

A blood gas electrode used to measure the carbon dioxide tension (symbolized as Pco₂) in blood. Its operation is based on the diffusion of carbon dioxide from the blood sample through a semipermeable membrane into a buffer solution with a subsequent change in the pH of the buffer. Synonym: Severinghaus electrodeSee also: electrode

Severinghaus,

John W., U.S. physiologist and anesthesiologist, 1922–. Severinghaus electrode - commonly used to analyze arterial blood samples. Synonym(s): carbon dioxide electrode
