Hemodynamic changes such as increased heart rate and mean aortic pressure reduce intraaortic balloon volume, with variations observed across different commercially available drivers, highlighting the need for console improvements.
Driver-specific IAB volume reductions with rising HR and pressure in animals; leaves open need for clinical validation of console performance.
The effects of hemodynamic changes on intraaortic balloon (IAB) volumes were studied experimentally using a helium tachometer in a mock circulatory system. The IAB volume decreased with increases in the heart rate and mean aortic pressure, but the degree of reduction in the IAB volume was different among 4 commercially available IAB drivers. Improvements in IAB consoles are needed to compliment the progress made in percutaneous techniques for IAB insertion resulting in smaller balloons.
