Which device helps the heart pump blood and is inserted into the aorta?

• A. Intra-Aortic Balloon Pump
• B. Dialysis Machine
• C. Feeding Pump
• D. Syringe Pump

Answer: (A)

It’s about a device that supports the heart’s pumping by counterpulsation—placing a balloon inside the aorta to help blood flow. An intra-aortic balloon pump is inserted via a major artery and positioned in the descending aorta just below the left subclavian artery. It inflates during diastole to push more blood into the coronary arteries, then deflates just before systole to reduce the heart’s workload and afterload. This external support aids the heart’s pumping without replacing its function. The other devices mentioned don’t sit in the aorta or assist pumping in this way: a dialysis machine filters blood externally, a feeding pump delivers nutrition, and a syringe pump delivers precise small volumes of fluid.
