The Perfusion department has different machines for different functions: The Perfusion department has different machines for different functions: –Heart lung machine. Which is used for open heart surgery. –VAD –ECMO –CPS –IAPB

Intra Aortic Balloon Pump Intra Aortic Balloon Pump is a cardiac assist device which provides temporary circulatory support.Intra Aortic Balloon Pump is a cardiac assist device which provides temporary circulatory support. It supports the heart’s left ventricle by increasing coronary perfusion while reducing left ventricular work.It supports the heart’s left ventricle by increasing coronary perfusion while reducing left ventricular work. Coronary perfusion is increased by augmenting ( increasing ) blood pressure during the diastolic phase of the cardiac cycle.Coronary perfusion is increased by augmenting ( increasing ) blood pressure during the diastolic phase of the cardiac cycle.

Countrepulsation is the active process of mechanically displacing intra aortic blood by inflating and deflating opposite to the heart’s activity. This is were it gets the name. The IAB System is comprised basically of two entities: 1.Balloon. 2. Console. The intra aortic balloon comes in various sizes and designs. However, they all function to displace blood from the aorta. The balloon functions by inflating and deflating with specific driving gas.

The various balloon use either carbon dioxide or Helium as the inflating gas. Atmospheric air can also be used to inflate the balloon, but is rarely used. There are specific reasons for using carbon dioxide and helium. Carbon dioxide is eighteen times more soluble in blood than air and fourty times more soluble than helium.

1. The bidirectional balloon. 2. The unidirectional balloon.

Arrow ACAT1+ ThereThere are three manufactured ( IABP ) console. – 1. – 1. Arrow (Bard, Kontron, Cardiac Assisst-BSC ) – 2. – 2. Datascope – 3. – 3. Smec Datascope

Diagrammatic representation of average timing of electrical and mechanical events on both sides of the heart during atrial and ventricular systole in normal subjects.(1) Onset of right atrial contraction,(2) onset of left atrial contraction, (3) onset of left ventricular contraction, (4) onset of right ventricular contraction, (5) onset of right ventricular ejection, (6) onset of left ventricular ejection, (7) end of left ventricular ejection, (8)end of right ventricular ejection. Striped areas represent ventricular isometric contraction.

1.Refractory ventricular failure. 2.Cardiogenic shock. 3.Unstable angina. 4.Impending infarction. 5.Mechanical complication due to a cute myocardial infarction,i.e, VSD, MV regurgitation or papillary muscle rupture. 6.Septic shock.
