Abstract

En fysiologisk avfølende anordning for målingen av pC02 inkluderer et lukket kammer avgrenset, minst delvis, av en karbondioksidpermeabel membran (12). Det er to elektroder (10) inne i kammeret. Kammeret inneholder en vesentlig elektrolyttfri væske i kontakt med elektroder (10) og membranen (12). Væsken inneholder en ikke-ionisk eksipiens for å forhindre vannutgang på grunn av en osmotisk gradient over membranen (12) i bruk.
