Analysers using a polarographic electrode had a tendency to react to nitrous oxide, which was considered dangerous with one analyser. However, they had cheaper running costs and a faster response time than the galvanic-cell analysers. These latter analysers were slightly cheaper initially but their sensors were expensive and had a reduced life in the presence of nitrous oxide. Details of accuracy tests have been presented and opinions expressed with regard to the most satisfactory analysers for clinical use.
