A new biomedical sensor for measuring PCO2

2 sensor is used. However, they are difficult to apply for the clinical real-time measurements. The basic principle of a PCO 2 sensor has been unchanged since it was first reported by Stow et al (1957) and then further developed by Severinghaus and Brandley (1958). The sensor had a gas-permeable membrane with a thin liquid film positioned behind it. In the

A Measuring Instrument for In-Line and Real-Time ...

17-08-2020· Abstract: Since the late 1950s, blood pCO 2 can be measured by using electrodes and, more recently, also by using point-of-care instruments such as blood gas and chemistry analyzers. Nevertheless, nowadays no measurement method has succeeded in providing an economic, reliable, and accurate estimate of the blood-pCO 2 to be routinely used for the monitoring of extracorporeal (blood…

11-11-2013· Local heating increases the local blood circulation in the capillary bed below the sensor. As a result, capillary P co 2 is similar to arterial P co 2 ( 48 ). Methodological limitations are caused by stabilization time (5–10 min), reaction time (5–10 s) ( 49 , 50 ), periodic repositioning of the sensor ( 51 ), the need for membrane restoration, and baseline calibration ( 52 ).
