ECLS / ADULT ECMO | 2026 UPDATE | QUESTIONS
AND ANSWERS | WITH COMPLETE SOLUTION!!
What falls into the category of ECLS? Answer - ECPR
- Massive PE
- Post cardiotomy Support
- Veno- venous rewarming for hypothermia
ECCOR Answer - Extracorporeal CO2 removal
*this is VV ECMO
EISOR Answer - Extracorporeal Interval support for Organ Retrieval
Is ECMO a treatment? Answer - No, it is a tool used to provide support
When is ECMO used? Answer - 1. Cardiogenic Shock
2. Refractory cardiac arrest - ECPR
,3. Bridge to device / transplant
When would VV ECMO be. used? Answer - 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 Answer - 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 Answer - 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 Answer - Natural 3000 mL/min
Artificial: 200-250 mL/min
What does it mean that ECMO is partial bypass? Answer - there is no cross
clamp and the heart is still beating often when on ECMO
How does ECMO servo regulate? Answer - 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)
2. Centrifugal pumps do not need servo control of this
ACT range for ECMO Answer - 180 to 200 seconds
How is heparin given? Answer - A small heparin bolus
