Abstract :
A sample taking sensor system for online pH, pO2, pCO2 and electrolyte 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 a silicon chip with chemically sensitive field effecttiansistors (ChemFETs) and electrode systems for potentiometric and amperometric transducer principals. In vitro measurements and animal studies with anaesthetized pigs have shown good correlation with standard analyzer equipment.
