Congenital heart disease

Acute renal failure before ECMO

Chronic renal failure before ECMO

Liver failure before ECMO

Central nervous system dysfunction before ECMO

Cardiac arrest before ECMO cannulation

Pre-ECMO peak inspiratory pressure ≤20 cm H₂O

Worst pulse pressure ≤20 mm Hg within 6 hours before ECMO

Pre-ECMO serum bicarbonate ≤15 mmol/L

Worst diastolic BP ≥40 mm Hg within 6 hours before ECMO
