title: [A simple modification for the electrochemical oxygen analyzer to improve accuracy during prolonged closed system anaesthesia (author's transl)].
abstract: A simple modification of the condenser used with the electro-chemical oxygen analyzer (Dräger BioMarine OA202 R) consists of filling the distal chamber with hygroscopic silicagel. This prevents condensation of water vapour on the sensor thus allowing the accuracy during prolonged closed system anaesthesia to remain nearly unaffected (fade less than 0.5%/h).
