Abstract

A method for non-destructive testing for approximation of oxygen transmission in hollow fiber blood oxygenators or the like is provided which method includes passing a first fluid at a predetermined temperature and volume flow rate through the hollows of the fibers and a second fluid at a second predetermined input temperature and volume flow rate across the outside of the fibers and measuring the heat rise or fall of the fluids and comparing the results with standards for a given blood oxygenator device.
