ABSTRACT
The article presents information on the use of photoelectric measurements of blood flow rate during hemodialysis for determining hemodialyzer performance. The light-sensitive areas of phototransistors are normally darkened by blood contained in the tubing between light source and transistors. Measurement accuracy can be improved considerably when tubing length permits use of a longer race-track, since any variation in the timing relationship between bubble injection and stroke becomes an increasingly smaller increment of total transit time.
