摘要：

An application of an optochemical oxygen sensor to respiratory gas monitoring is presented. A new prototype module has been developed, which is suitable for the determination of oxygen concentration in mainstream breath-gas flow, directly at the patient's mouth. The sensor is based on the measurement of the quenching of the intensity of photoluminescence of the dye platinum(II)-octaethylporphyrin-ketone by molecular oxygen. The dye has been immobilized in various polymers with and without plasticizer. The characteristics of the resulting oxygen sensitive membranes have been determined with emphasis mainly on their oxygen response characteristics, such as calibration graphs, oxygen sensitivities, oxygen resolution and response times. The suitability of the optochemical oxygen sensors for clinical use in respiratory gas-exchange measurements has been demonstrated in combination with a prototype instrument.
