VA ECMO Max Flow 100-120 ml/kg/min
VV ECMO Max Flow 120-150 ml/kg/min
Idle Flow 50 ml/kg/min
1:1 ratio between pump flow rate and sweep gas flow
Initial Sweep gas flow rate
rate
Pediatric Oxygenator 0.5 LPM
minimum flow rate
Adult oxygenator minimum 1 LPM
flow rate
Heparin Loading Dose 50-100 units/kg
Heparin Continuous 20 units/kg/hr
Infusion rate
AntiXa range 0.3 - 0.7
ACT Level for cannulation >300
ACT normal range 180-220
Family or patient directives to limit resuscitation
Gestational age <34-36 weeks
ECMO Contraindications <2 kg
Uncontrolled bleeding
IVH grade III or IV
ACT level to begin ACTs <250
anticoagulation
maintenance
HCT normal range 30 - 40
Platelets >100 - 150
, Fibrinogen >150 - 250
INR <2
ATIII Level >80%
Blood dosage level 10 - 15 ml/kg/hr
Products safely Blood, FFP, & Albumin
administered
preoxygenator
Products safely Platelets, cryo, & lipids
administered
postoxygenator
Max flow 2.8 LPM
Prime volume 81 ml
Pediatric oxygenator specs
Pt. Weight <15 kg
Circuit size 1/4"
Max flow 7 LPM
Prime volume 250 ml
Adult oxygenator specs
Pt weight >15 kg
Circuit size 3/8"
If you have a clot in the Pressure gradient will remain the same, both pressures
arterial cannula, what will will rise
happen to your pressure
gradient?
Clues recirculation is Decreased patient saturations with increased SVO2
happening
Increase HCT
VV ECMO options to
Sedation/paralysis/cooling
increase systemic O2
Increase venous drainage/add another cannula
delivery
Add another ECMO membrane oxygenator
1. Pump Flow
The four factors that affect 2. Cannula Position
recirculation 3. Volume Status
4. Cardiac Output
Recirculation is directly influenced by pump flow
- large cannulae can decrease the amount of
Pump Flow recirculation
- percentage of recirculation increases linearly with
pump flow
