low SPO2 and high SVO2
return and access are RED
What are some signs of recirculation seen due to femoral
drainage ?

Increase in plasma free Hgb
1 pump flow
What are the 4 factors of recirculation with VV ECMO? pg 2 cannula position
125 from manual 3 cardiac output
4 intravascular volume (right atrial size)
How do you care for a patient on ECMO during cardiac establish adequate flow???
arrest? CPR
1 pump flow
When weaning off ECMO, what are the 3 variables that can
2 FIO2
be adjusted on the ECMO system ?
3 sweep rate
What happens when the cardio help is on LPM mode and
you clamp the arterial line?
VA ECMO indicated for lung failure only? t/f False
VA ECMO is advantageous in patients with heart and lung
true

Main difference between VV and VA ECMO is that VV pro-
true
vides no direct cardiac support. t/f
When assessing patient oxygenation status on VA ECMO,
pre membrane oxygen sats
which is the best indicator of adequacy of oxygenation?
There are no absolute contraindications to ECLS? t/f false
Increasing ECMO blood flow in response to a low patient
arterial sats in VV ECMO may cause a decrease in oxygen true
delivery. t/f
Oxygen exchange in membrane lung effected by all EX-
blood path thickness
CEPT the following:
Centrifugal pumps exhibits the following characteristics: pre load dependent and after load dependant
Centrifugal pump is set at 3600RPM and reading 4.3LPM.
If the patient pressure increases, what would you expect decrease
the LPM to do?
When using the cardio help the flow/bubble detector
arterial
goes on what limb?
Avalon cannula is commonly used for VA ECMO. t/f false
The cardio help circuit has a bioline coating that contains
heparin and albumin
what?
What is the gold standard anticoagulant used with ECMO? heparin
Which drug rapidly neutralizes heparin? protamine
What test measures the effect of heparin ? ACT
Why would we choose to use argatroban over heparin? Heparin induced thrombocytopenia
What is the lowest recommended flow when weaning.
1LPM
from VA ECMO?
When trialing off of VV ECMO the arterial and venous line
false
must be clamped off to the patient. t/f
