Monitoring of the dilution rate during continuous in vivo blood sampling with a double lumen catheter.
A simple and non-destructive method for monitoring the dilution rate during continuous blood sampling is described. When the dilution rate is not constant, the proposed method based on electrical resistivity measurement provides a correction factor for further analysis.
