Unformatted text preview: INTRA AORTIC BALLOON PUMP Group 8 OVERVIEW Terms related to IABP Waveform What is IABP History of IABP Insertion of IABP Devices Used for IABP Main Function of IABP Insight on IABP Block Diagram of IABP Benefit and Risks of IABP Alternatives and Variants TERMS RELATED TO IABP Coronary Arteries Right coronary artery Left coronary artery Myocardial oxygen supply and demand Heart Rate Contractibility After Load Pre Load PRESSURE WAVEFORM The peak pressure is referred to as the systolic pressure and the minimum pressure is referred to as the diastolic pressure. The period from diastolic point to diastolic point is referred to as the heart rate. The period from diastolic point to dicrotic notch is referred to as the ejection time. WHAT IS IABP? The device consist of a balloon- tipped catheter which is placed in the descending thoracic aorta via the femoral artery. It is connected to a gas-driving unit which inflates the balloon during diastole and which deflates during systole. HISTORY OF IABP Introduced in 1960 to increase coronary blood perfusion. Clinical practice and further improvement continued by A. Kantrowizs group in 1968. Introduction of percutaneous IABP in 1979. First prefolded IABP developed in 1985. APPLICATIONS OF IABP Failure to wean from cardiopulmonary bypass. Cardiogenic shock. Heart failure. Acute heart attack. Support during high-risk percutaneous transluminal coronary angioplasty and coronary stent placement. IABP INSERTION Heparinize patient prior to insertion of catheter. Fully collapse the balloon applying 30 ml vacuum with 60 ml syringe. Insert needle into femoral artery at 45 and pass it through both walls of artery. Withdraw needle until strong pulsatile jet of blood is obtained. Pass guide wire through needle and advance until tip is in the thoracic aorta. IABP INSERTION Pass a sheath over the wire, and then pass the balloon over the guide wire through the sheath. Balloon situated 1-2cm below the origin of the left subclavian artery and above the renal artery branches. Confirm placement of balloon by fluoroscopy or chest X-ray....
