What are cannulation sites for an LVAD? Pulmonary Vein and Aorta
What is the minimum pressure for an LVAD 5 mmHg
inflow, before you are at risk for drawing
air?
Correction for cannula entrapment in increasing the left atrial preload (decreasing flow)
LVAD's can be accomplished by doing --> Cannula is sucking down in the LVAD inflow either in the pulm vein, lv apex, or just
what? below crossing the aortic valve.
What is the indication that indicates to add Right atrial pressure >20 mmHg with IABP and inotropic support
an RVAD?
Cannulation sites for RVAD support? Right atrium and pulmonary artery.
Which would not be an important C. Cannula Circuit Connector Size
consideration in cannula selection?
A. size B. Shape C. Cannula Circuit
connector Size D. Flow requirements
Right Ventricular flow rates should be Left ventricular flow rate.
adjusted in relation to what?
In RVAD's, pump inflow cannula snapping or chattering of the line
entrapment is indicated by?

entrapment?
When is heparin therapy to maintain Within 24 hours after initial bleeding from surgery has been controlled. Sometimes
coagulation in VAD's usually started? patients will get protamine. ACT's should be between 150-200 seconds.
When do patients diagnosed with atrial 1:1.5
petal defects become diagnosed in
relation to Qp/Qs ratio?
