Abstract
The effects of hemodynamic changes on intraaortic balloon (IAB) volume s were studied experimentally using a helium tachometer in a mock circ ulatory system. The IAB volume decreased with increases in the heart r ate and mean aortic pressure, but the degree of reduction in the IAB v olume was different among 4 commercially available IAB drivers. Improv ements in IAB consoles are needed to compliment the progress made in p ercutaneous techniques for IAB insertion resulting in smaller balloons .
