Effect of the Sampling System on the Shape of Indicator Dilution Curves
This paper describes the distorting effects produced by various sizes of polyethylene tubing and various flow rates on a square wave input of dye concentration. The importance of an accurate sampling system when recording dilution curves for analysis of their shape is emphasized and the distortion caused by inadequate sampling systems is demonstrated in vivo.
