ECMO Flashcards
1
Q
What are the two broad types of ECMO
A
1) Venous - Venous
2) Venous - Arterial
2
Q
how do you modulate C02 in the ECMO circuit
A
sweep gas (inc sweep -> dec C02)
3
Q
What is the most important factor in myocardial 02 demand
A
wall tension
4
Q
What are three causes of LV distension when on ECMO
A
1) Venous return not captured by the venous line
2) bronchial and thebesian veins
3) incompetent AV valve
5
Q
What LV pressure do you want to avoid
A
above 20-25 mmHg
6
Q
What with regards to the LV functioning do you need to ensure when on ECMO
A
You want some activity
7
Q
How do you ensure LV ejection (e.g. no stagnant blood) when on ecmo
A
1) inotrops
2) decreasing ecmo flow
3) impella
4) direct LV venting
