Description
The CS100 Intra-Aortic Balloon Pump (IABP) is a cardiac assist device. It supports the heart’s left ventricle by increasing coronary perfusion and reducing left ventricular work. Coronary perfusion is increased by augmenting blood pressure during the diastolic phase of
the cardiac cycle. This increase in aortic pressure forces more blood flow through the coronary arteries. Left ventricular work is reduced by reducing the amplitude of blood pressure during the systolic phase of the cardiac cycle. These beneficial effects are caused by the inflation and deflation of an intra-aortic balloon (IAB) in the patient’s descending aorta. The balloon’s inflation and deflation must be properly synchronized with the cardiac cycle. IAB inflation is initiated at the onset of diastole at the dicrotic notch. The IAB is held inflated through diastole and is deflated at, or just prior to, the onset of systole. The balloon is held in the deflated state throughout systole.
