Abstract : The intra-aortic balloon pump is the most widely used mechanical assist device for hemodynamic support in high-risk patients undergoing heart surgery (IABP). The purpose of this research is to determine if the catheter is in the best possible position, as poor positioning might result in adverse side effects such a blockage of the subclavian or renal arteries. This study comprised ten individuals with severe coronary artery disease who received coronary artery bypass grafting. These patients could not be weaned off cardiopulmonary bypass and needed IABP. The designed system of sensors was used to measure the perfusion index and doppler for monitoring blood flow through the hand and kidney during the insertion of the IABP catheter into the femoral artery. All the patients underwent the surgery satisfactorily. IABP assistance lasted an average of hours. The use of this sensing device was not associated with any in-hospital mortality or problems. This method is straightforward, dependable, and aids in the reduction of unwanted balloon catheterization side effects.
