Solution

The correct option is B Helium
The intra aortic balloon pump (IABP) is a cylindrical polyethylene balloon that is fitted in the aorta, approximately 2 centimeters from the left subclavian artery. A computer controlled mechanism inflates the balloon with helium gas from a cylinder during diastole, usually linked to an electrocardiogram (ECG). Helium is used because its low viscosity allows it to travel quickly through the long connecting tubes, and has a lower risk than air of causing an embolism if the balloon ruptures.
