ECLS / ADULT ECMO | 2026 UPDATE |
QUESTIONS AND ANSWERS | WITH
COMPLETE SOLUTION!!
When would VV ECMO be. used? - ANSWERS-PF ratio lower than 150
High CO2 - pH less than 7.2
3. Pre-or post lung trasnplant
Natural Lung vs. Native lung
Membrane surface area - ANSWERS-Membrane Surface area:
Natural: 70m^2 and 1-3 microns thick
Native: 2-4 m^2 and 10-30 microns thick****
Natural lung vs. artificial lung
,Exchange volume - ANSWERS-Natural: 5 L
Artificial: ~300 mL
Capable O2 delivery and CO2 removal of natural vs. Artificial lung
>?? I think this is O2 delivery / CO2 removal - ANSWERS-Natural 3000
mL/min
Artificial: 200-250 mL/min
What falls into the category of ECLS? - ANSWERS-ECPR
- Massive PE
- Post cardiotomy Support
- Veno- venous rewarming for hypothermia
ECCOR - ANSWERS-Extracorporeal CO2 removal
, *this is VV ECMO
EISOR - ANSWERS-Extracorporeal Interval support for Organ Retrieval
Is ECMO a treatment? - ANSWERS-No, it is a tool used to provide
support
When is ECMO used? - ANSWERS-1. Cardiogenic Shock
2. Refractory cardiac arrest - ECPR
3. Bridge to device / transplant
What does it mean that ECMO is partial bypass? - ANSWERS-there is
no cross clamp and the heart is still beating often when on ECMO
How does ECMO servo regulate? - ANSWERS-1. One way is through
Venous return
*don't want pressures to be negative if a roller pump sucks air out of
solution
*this would collapse plates (bladder)
