摘要：

A self-calibrating sample-taking sensor system for online pO2, pCO2 and pH monitoring is presented. The system consists of a two-lumen catheter with a sensor flow-through cell, a pump unit with instrumentation and a personal computer. The sensor device is based on an integrated silicon chip containing chemically sensitive field-effect transistors (ChemFETs) with CMOS signal-processing and thin film electrode systems for potentiometric and amperometric transducers. In vitro measurements and animal studies with anaesthetized pigs show good correlation with standard analyzer equipment.
