centrifugal pump
Blood flow rate!
*can also increase O2 concentration of sweep gas and
What is oxygenation
blood but dosen't change as quick
dependent on?
*can also increase Hgb and Hct, decrease oxygen
demand
What is Co2 exchange Sweep gas flow rate!
dependent on? to decrease Co2, increase sweep gas rate
What is the max calculate 120cc/kg/min
flow for VA ECMO?
How quickly should you 20-30 minutes
reach max flow for VA For neuro-protection
ECMO? Why?
Single site: RIJ with double lumen cannula
What are the 2 options for
Multi site: >20kg- Femoral drain, RIJ return
cannulation in VV ECMO?
<20kg- Femoral return, RIJ drain
In VV ECMO: if patient sats Recirculation
are decreasing and pre-
membrane saturation's are
increasing, what could that
indicate?
1. Flow rate
What are the four factors 2. Catheter position
affecting recirculation? 3. Cardiac output
4. RA size/volume
_____________ flow= that which Effective
delivers the most O2 at the define the curve
lowest RPMs
, What is the most accurate Patient arterial saturation
indicator of patient
oxygenation in VV ECMO?
What is the max calculated 150cc/kg/min over 10-15 minutes
flow rate for VV ECMO?
How quickly can you
achieve it?
Bacterial/viral pneumonia
Name a few common
Near drowning
indications for pediatric
Flu, RSV, COVID
ECMO.
Myocarditis
What size tubing is used for Based on weight:
the centrifugal pump and Toddler; >6kg= 1/4" tubing
what is it based on? Ped/adult; >15kg=3/8" tubing
What is the max calculated 200cc/kg/min
flow for a cardiac ECMO
patient?
What pump flow do you 20cc/kg/min
start all patients out?
At what increments do you Infants: 10-20cc/min
wean the pump flow in Pediatrics: 100-200cc/min
infants? Pediatrics? wean total flow, not per kg!
VV: 40-50 cc/kg
At what point do you wean
VA: 20-30cc/kg
TO in VV? VA? VA/Cardiac?
Cardiac: 5-10cc/kg
What is the minimum flow Roller head: 200cc/min
that must be maintained for Centrifugal: 300cc/min for 1/4"; 500cc/min for 3/8"
circuit integrity?
What is the best indicator pre-membrane saturation
of adequacy of
oxygenation for a patient
on VA ECMO?
Increase ECMO flow*
Transfuse*
