Patient SpO2 increases, O2 is improving. May decrease ECMO blood flow and
Post Ox O2 increases, pre adjust sweep.
Ox O2 stable..
Interpretation and
Management?

Patient SpO2 decreases, O2 is worsening. Increase ECMO flow. Confirm catheter
Post Ox O2 decreases, pre positioning and pump flow.
Ox O2 stable or decreases..
Interpretation and
Management?

Patient SpO2 decreases, Recirculation (change in catheter position). Adjust
Post Ox O2 stable but with catheter position, consider adding an additional
decreased flow, pre Ox O2 drainage cannula.
increases.. Interpretation
and Management?

Patient SpO2 decreases, High CO relative to ECMO blood flow. Adjust catheter
Post Ox O2 decreases or position, sedation, NM blocking, BB if no end organ
stable with good flow, pre dysfunction. Evaluate cardiac output.
Ox O2 stable or decreases..
Interpretation and
Management?

Patient SpO2 decreases but Decreased ventilation. Increase sweep.
stable but increased
PaCO2, Post Ox O2
increased with increased
flow, pre Ox O2 stable..
Interpretation and
Management?

, Patient SpO2 stable but Increased ventilation. Decrease sweep.
with decreased PaCO2,
Post Ox O2 decreased with
decreased flow, pre Ox O2
increases.. Interpretation
and Management?

Patient SpO2 decreases Decrease in cardiac output. R/O tamponade, tension
with hemodynamic pneumothorax, review TTE, look for shock states.
instability, Post Ox O2 Transition to VA ECMO.
decreased with decreased
flow, pre Ox O2 increases..
Interpretation and
Management?

When weaning VA ECMO, EF > 20-25%, aortic VTI (velocity time integer) > or = to 12
what are the final cm, and tissue doppler lateral mitral annulus peak
considerations as far as EF, systolic velocity TDSa > or = to 6 cm.
aortic VTI (velocity time
integer), and tissue doppler
lateral mitral annulus peak
systolic velocity?

(Native CO x CaO2 of native lung (content of O2)) +
Oxygen delivery (DO2) =
(ECMO Flow x CaO2 of membrane lung))

VO2 / DO2 (O2 consumption/O2 delivery)
Extraction Ratio (ER) =
(SaO2 - SvO2) / SaO2

Intervention if decreased Increase ECMO flow.
DO2 secondary to
decreased CO, decreased
MAP leading to up-titration
of vasopressors?

Intervention if increased O2 Antipyretics, cooling, anti-shivering agents, increase
consumption due to fever, sedation.
shivering, etc.. ?

Intervention if decreased Transfuse PRBC to maintain HGB/HCT 10/30.
DO2 secondary to
decreased Hb?
