Increasing oxygen flow rate Decrease
will __________ the CO2 in the

No
Are hemodynamics
1. The volume of blood removed is equal to the volume
affected by VV ECMO?
returned.
Why or why not?
2. Drainage and return on same side of circulation
Is there an effect on CVP, No
Volume, or RV filling
pressures on VV ECMO?
, On VV ECMO Systemic True.
blood flow is the native
cardiac output and is
unrelated to the ECMO
flow. True or False?
1. Decrease mechanical vent support=more efficient gas
Myocardial function and exchange=decrease RV afterload=Improved RV function

in VV ECMO?
What factors improve 1. Low pressure circuit=Less stress on tubing and
longevity in VV ECMO oxygenator
