Right Ventricular flow rates should be adjusted in relation
to what? - Answer-Left ventricular flow rate.
In RVAD's, pump inflow cannula entrapment is indicated
by? - Answer-snapping or chattering of the line
What action can correct RVAD cannula entrapment? -
Answer-Increasing the right atrial preload. (slow flow)
When is heparin therapy to maintain coagulation in VAD's
