An Electric Device for Instantaneous and Continuous Computation of Aortic Blood Velocity
An electric device is described which computes the instantaneous aortic blood velocity from the pressure difference between two points along the aorta. The pressure difference was obtained from a specially designed double lumen catheter attached to a differential pressure gage. The aortic blood velocity curves obtained from 20 dogs compare closely with most of those appearing in the literature.
