Web18 Jun 2015 · As the aortic valve closes in end-systole (this correlates with the dicrotic notch) the IABP balloon inflation pushes blood against the closed valve. The beginning of diastole is the perfect time to inflate the balloon- during this time, there is the largest amount of blood in the aorta. As it inflates, the balloon displaces this volume upwards ...

The deflation of the balloon assists the left ventricle by decreasing the aortic end-diastolic pressure, by suddenly decreasing the aortic fluid volume. The aortic end … Webunassisted systole is followed right away by another, taller peak that arises from the dicrotic notch—^the fii'st negative deflec- tion after the unassisted systole— and ci'eates a 'V" shape between the two peaks.
