Final Assessment Flashcards
The Intra-aortic balloon is most commonly inserted through the:
Femoral artery
Volume and pressure inside the left ventricle at the end of diastole is referred to as:
preload
Volume and pressure inside the left ventricle at the end of diastole is referred to as:
afterload
Coronary arteries receive the majority of arterial blood supply during:
Diastole
The primary effects of intra-aortic balloon counterpulsation are:
increased myocardial O2 supply/decreased myocardial O2 demand
Intra-aortic balloons are indicated for:
ACS, cardiac and non-cardiac sx, complications of HF
Diastolic augmentation can be affected by:
- The pt (hemodynamics)
- The Catheter (position)
- the pump (timing)
Diastolic augmentation can be affected by:
- The pt (hemodynamics)
- The Catheter (position)
- the pump (timing)
Restriction of gas flow through the IAB may be caused by:
Kink in the catheter
SV may be decreaesd by:
tachycardia, decreased cardiac index, dysrhythmias
Two AV valves are:
mitral and tricuspid
two semilunar valves are:
aortic and pulmonic
the dicrotic notch signifies
the beginning of diastole
The intra-aortic balloon will be timed to inflate:
At the dicrotic notch (at the beginning of diastole)
The intra-aortic balloon will be timed to deflate:
Before the aortiv valve opens (just prior to systole))
Inflation of the IAB will result in:
augmentation of DBP and increased coronary perfusion
Deflation of the IAB will result in:
Decreased afterload and decrased myocardial O2 demand
Proper placement of the intra-aortic balloon catheter in a femoral artery insertion is with the tip of the catheter:
Just distal to the left subclavian artery
T/F: balloon placement does not affect diastolic augmentation
false
T/F: An intra-aortic balloon membrane could be abraded by calcific plaque, leading to a membrane leak.
true
Label A-F
A= unassisted systole
B= diastolic augmentation
C= assisted systole
D= unassisted end diastolic pressure
E= balloon inflation
F= assisted end-diastolic pressure
