Key term for VA-ECMO? Partial bypass
Key term for VV-ECMO? Partial capture
On which type of ECMO do you run a full code (with
VV-ECMO
compression)?
Which ECMO requires full drugs per ACLS but no com-
VA-ECMO
pressions in a code?
mL in an ECMO circuit? 800mL
mL in an ECMO circuit + CVVHD? 1100mL
In which type of ECMO is SvO2 utilized? VA-ECMO
- Clamp
- Call for help
What are the "3 C's" in an ECMO emergency?
- Compensate for losses in support with drugs and other
measures
What is the default anticoagulant used in ECLS? Heparin
- Accelerates the action of endogenous antithrombin.
What are the actions of heparin?
- Inhibits thrombin and factor Xa
What is the normal dose of heparin given at the time of
50 - 100 units / kg
ECMO cannulation?
What blood product is indicated for patients who are
FFP
heparin resistant 2/2 diminshed antithrombin levels?
What is the standard goal aPTT for ECMO patients being
50 - 75
heparinized?
Clotting that occurs when blood comes into contact with
Intrinsic pathway
a non-endothelial surface

Clotting that occurs by the release of tissue factor from
Extrinsic pathway
damaged tissue
Current survivial rate of patients put on ECMO for cardiac
23 - 71%
reasons?
- End-stage, irreversible, or inoperable cardiac disease.
- Significant neurological or end-stage renal impair-
ment.
What are some contraindications to ECMO? - Uncontrolled bleeding of major organs.
- Extremes of size or weight (relative)
- Inaccessible vessels during CPR (though femoral is usu-
ally accessible)
- Femoral Vein
- R IJ (if an Avalon Cannula)
Placement options for venous drainage of VV-ECMO?
Both drain venous blood from the SVC
- Right IJ
- Right Axillary vein
- Right Subclavian vein
Placement options for return blood of VV-ECMO?
All terminate in the RA with the outflow directed at the
Tricuspid valve.
What percentage of cardiac output is provided by
0%
VV-ECMO?
What percentage of cardiac output can be provided by
60 - 80%
VA-ECMO?
- Femoral vein
- Right IJ
Cannulation sites for venous drainage in VA-ECMO?
Both terminate in the SVC
Cannulation sites for arterial (return) cannula?
