Intra-Aortic Balloon Counterpulsation
Therapy answers
What decade did this become prominent?✔✔Late 1960's
Balloon pumps help with✔✔cardiogenic shock
Tip of Balloon✔✔2nd-3rd ICS (below aortic arch)
Balloon positioned between what?✔✔Between 2nd ICS and 6th ICS
Main artery of insertion✔✔Femoral
Systole✔✔heart is contracting
coronary artery is flattened
perfusion is NOT easy
Diastole✔✔Heart and Ventricles relax
Coronary arteries are perfusing
L Coronary Artery equals✔✔LV and RV and circulation feeds the atrium
Trickiest surgery is✔✔Aortic valve replacement because if there is any shift arteries
can get blocked
Shortens diastolic time and why✔✔Tachycardia- because the heart is pumping too
much therefore perfusion is decreased
Increases diastolic time and why✔✔bradycardia because tissue is being able to be
perfused
Increase afterload equals✔✔harder the heart has to work
increase preload equals✔✔too much volume, too much stretch therefore causing it
to become ineffective
Systole is what part on the ECG✔✔QRS
Systole widens only when what are present✔✔PVC's
Coronary Oxygenation Supply and Demand✔✔Coronary Artery Anatomy
Diastolic Pressure
Diastolic Time
Oxygen extraction
- Hb
-PaO2
Heart Rate
, Afterload
-pressure heart faces
Preload
-needs to be balanced
Contractility
-efficiency of heart muscle
Cardiac Output✔✔HR x SV
Normal 4-6 L/Min
Cardiac Index✔✔Cardiac Output/BSA
Normal
2.5-3.5 l/min/m^2
Left Ventricular Failure✔✔O2 supply decrease
O2 demand increase
*CO, BP effected by this imbalance. Balloon helps correct it*
Goal of IAB Therapy✔✔Increase O2 supply
Decrease O2 demand
Diastole✔✔inflation - pushes blood
(systole)
Systole✔✔deflation - easy to pump
Balloon is filled to what pressure✔✔40 cc
IAB Inflation( Diastole )✔✔Augmentation of diastolic pressure (pressure raised)
Increase coronary perfusion (inflated= blood displaced in 2)
Increase myocardial oxygen supply (O2 supply is increased to myocardium.
IAB Deflation (Systole)✔✔Decrease afterload
Decrease Cardiac work
Decrease myocardial O2 consumption
Increase cardiac output
Trigger and Timing✔✔ECF or Art pressure waveform
Which is more accurate in reading pressure✔✔Arterial Waveform
1:1 IABP Frequency✔✔1 balloon inflation/ 1 cardiac cycle
*High Peak diastole
*Low end diastole
