ECMO use right arterial line to rule out north south syndrome
- NS syndrome: blood going to brain is less oxygenated than blood going to distal peripheral
- ECMO can have deoxygenated blood from heart mixing with oxygenated blood returning from machine. There is usually a watershed area with little oxygen. Check bilateral ABG for difference in oxyenation 1
- You can use VAV ECMO to help with hypoxemia
- put pulse ox on right hand or use right ABG because the right side will have least amount of good O22
