Samples at room temperature were taken at 15 and 30 minute intervals for 4 to 5 hours. Samples were spun down and hemolysis measured immediately using the method of FLINK & WATSON. Since the rate of hemolysis depends on the amount of blood in the system and the flow rate, the results are reported as mg % per pass. The flow rate divided by the volume of blood in the system determines the number of passes through the pump per minute. Hemolysis ranged from 0.114 mg % to 0.27 mg % per hour pass through the various pumps with an error of ± 10%. To put these results in perspective most physiological perfusions are run with flow rates and total blood primes, so that the number of passes through the pump will range from about 1/4 to 3/4 per minute. Assuming one pass in two minutes and no physiological removal of the products of hemolysis,then hemolysis rates would range from 3.4 mg % to 8.7 mg % per hour of pump use.
