RECRUITINGThe effectiveness of the oxygenator in ensuring adequate gas exchange
To ensure adequate oxygenation (post-membrane pO2 \> 150 mmHg during the first week of use) and CO2 elimination (post-membrane pCO2 \< 40 mmHg or pre-membrane pCO2 - post-membrane pCO2 \> 10 mmHg)
Time frame: during the first week of use
The effectiveness of the set in ensuring adequate flow to the patient
Nominal flow calculated according to weight or body surface area (50 to 80 mL/Kg or 2.4 L/min of body surface area
Time frame: during the use of extracorporeal membrane oxygenation
Rate free of membrane dysfunction
percentage of oxygenators free from dysfunction
Time frame: during the use of extracorporeal membrane oxygenation
Need for oxygenator due to dysfunction
percentage of oxygenators that needed to be replaced due to dysfunction
Time frame: during the use of extracorporeal membrane oxygenation
Decannulation rate
percentage of patients who were decannulated from ECMO
Time frame: during the use of extracorporeal membrane oxygenation
