ECLS / Adult ECMO
Study online at https://quizlet.com/_9sk6hd
ECPR
- Massive PE
What falls into the category of ECLS?
- Post cardiotomy Support
- Veno- venous rewarming for hypothermia
Extracorporeal CO2 removal
ECCOR
*this is VV ECMO
EISOR Extracorporeal Interval support for Organ Retrieval
Is ECMO a treatment? No, it is a tool used to provide support
1. Cardiogenic Shock
When is ECMO used? 2. Refractory cardiac arrest - ECPR
3. Bridge to device / transplant
PF ratio lower than 150
When would VV ECMO be. used?
High CO2 - pH less than 7.2
3. Pre-or post lung trasnplant
Membrane Surface area:
Natural Lung vs. Native lung
Natural: 70m^2 and 1-3 microns thick
Membrane surface area
Native: 2-4 m^2 and 10-30 microns thick****
Natural: 5 L

Natural lung vs. artificial lung
Artificial: ~300 mL
Exchange volume
Capable O2 delivery and CO2 removal of natural vs. Artifi-
Natural 3000 mL/min
cial lung
Artificial: 200-250 mL/min
>?? I think this is O2 delivery / CO2 removal
there is no cross clamp and the heart is still beating often
What does it mean that ECMO is partial bypass?
when on ECMO
1. One way is through Venous return
*don't want pressures to be negative if a roller pump sucks
air out of solution
How does ECMO servo regulate? *this would collapse plates (bladder)
2. Centrifugal pumps do not need servo control of this
ACT range for ECMO 180 to 200 seconds
A small heparin bolus
How is heparin given? then
A continuous heparin drip
CAN NOT introduce air into venous side
1. Air will travel to arterial side
- can be trapped in venous bladder OR expleeted through
oxygenator
