What patient population Severe cardiac and respiratory failure patients
uses ECMO?
1. Veno-Venous (VV) ECMO
What are the two types of
ECMOs?
2. Venous-arterial (VA) ECMO
VV ECMO is used for Respiratory
______________ support
A patient must have _________ preserved cardiac
function in order to use VV
ECMO
1. 2 Separate Cannulas What are the two Canula configurations for VV ECMO
2. Dual Lumen Cannula
In the 2 separate cannula Drainage:
configuration. B: Inferior Vena Cava
A: Femoral Vein
The drainage tube starts
from the _____________ and exits Return:
the _________________ C: Right internal Jugular Vein
D: Superior Vena Cava
The return tube enters
the____________ and into the
__________________
How is the dual lumen Dual Lumen is a single insertion in the right internal
cannula different from the 2 jugular vein
separate cannula
configuration? Both Drainage and Return occur in the Right IJ
, In the Dual Lumen Cannula Drainage:
configuration. C: Inferior Vena Cava
A: Right internal Jugular Vein
The drainage tube starts
from the _____________ and exits Return:
the _________________ A: Right internal Jugular Vein
B: Tricuspid Valve/Right Ventricle
The return tube enters
the____________ and into the

What is a major issue with Recirculation
VV ECMO
Oxygenated Blood from the return cannula pulled into
the ECMO circuit by the drainage cannula
Recirculation Oxygenated blood is taking up the space of
deoxygenated blood (deoxygenated blood stays in the
body) and oxygenated blood does not need help from
the ECMO circuit
1. Cannula Configuration Position
2. High Flow Rates
Causes of Recirculation
3. Cannula Size
4. Intrathoracic/cardiac/ and abdominal pressure:
increased pressue
How do you identify if Increase in pre oxygen saturation and decrease in
recirculation is occurring in arterial oxygen saturation
a patient?
In VV ECMO, blood flow a mix of blood flow from ECMO and Native Blood flow
occurs with (intact cardiac function)
When determining Hemoglobin Concentration
oxygenation what should
be monitored to provide a
good indicator of
oxygenation?
