Which of the following statements BEST describes how the intra-aortic balloon pump (IABP)facilitates an increase in cardiac output?

Question

Quizplus · Accepted Answer

When the IABP is activated,the balloon is inflated during diastole as soon as the aortic valve closes.The increase in intra-aortic and diastolic pressures forces the blood in the aortic arch to flow in a retrograde direction into the coronary arteries.When the balloon is deflated during left ventricular systole,it lowers the left ventricular systolic pressure and the afterload by forcing the blood to move from an area of higher pressure to one of lower pressure enhancing the cardiac output.
