Table 1 Hypoxemia during extracorporeal membrane oxygenation (ECMO): causes and recommendations
Causes | Recommendations |
|---|---|
Recirculation | Check the position of the cannulae |
Low flow with regards to metabolic demand | Adapt the diameter of the cannulae and correct hypovolemia |
Failure of the oxygenator | Measure post-oxygenator blood gases |
Inhibition of hypoxic pulmonary vasoconstriction and worsening of the pulmonary shunt | Measure pre, post-oxygenator and patient blood gases |
Worsening of the pulmonary disease | Â |
