Abstract :
A flow system modeling the right heart for the study of thermodilution was designed and constructed for use in an undergraduate teaching laboratory. The flow system was used to validate the thermodilution method for three known flow rates. Results show a linear relationship between the thermodilution and the known flow rates, however, thermodilution overestimates the true flow
