Ecmo Study Questions with Complete
Solutions
Terms in this set (103) Questions Verified Answer
1. Key term for VA-ECMO? Partial bypass
2. Key term for VV-ECMO? Partial capture
3. What are 3 factors that affect oxygen delivery? - Hemoglobin
- Cardiac Output /
ECMO flow
- Oxygen saturation
4. On which type of ECMO do you run a full code (with VV-ECMO
compression)?
5. Which ECMO requires full drugs per ACLS but no VA-ECMO
compressions in a code?
6. mL in an ECMO circuit? 800mL
7. mL in an ECMO circuit + CVVHD? 1100mL
8. In which type of ECMO is SvO2 utilized? VA-ECMO
9. What are the "3 C's" in an ECMO emergency? - Clamp
- Call for help
- Compensate for losses
, in support with drugs
and other measures
10. What is the default anticoagulant used in ECLS? Heparin
11. What are the actions of heparin? - Accelerates the action
of endogenous
antithrombin.
- Inhibits thrombin and
factor Xa
12. What is the normal dose of heparin given at the time 50 - 100 units / kg
of ECMO cannulation?
13. What blood product is indicated for patients who are FFP
heparin resistant 2/2 diminshed antithrombin levels?
14. What is the standard goal aPTT for ECMO patients 50 - 75
being heparinized?
15. Clotting that occurs when blood comes into contact Intrinsic pathway
with a non-endothelial surface
16. Clotting that occurs by the release of tissue factor Extrinsic pathway
from damaged tissue
17. Current survivial rate of patients put on ECMO for 23 - 71%
cardiac reasons?
18. What are some contraindications to ECMO? - End-stage, irreversible,
or inoperable cardiac
disease.
, - Significant
neurological or end-
stage renal impairment.
- Uncontrolled bleeding
of major organs.
- Extremes of size or
weight (relative)
- Inaccessible vessels
during CPR (though
femoral is usually
accessible)
19. Placement options for venous drainage of VV- - Femoral Vein
ECMO? - R IJ (if an Avalon
Cannula)
Both drain venous blood
from the SVC
20. Placement options for return blood of VV-ECMO? - Right IJ
- Right Axillary vein
- Right Subclavian vein
All terminate in the RA
with the outflow directed
