Notes

• RESP: Respiratory ECMO Survival Prediction; ECMO: extracorporeal membrane oxygenation; CNS: central nervous system.

Calculation Details and Variables

• AgeFactor is assigned values by this ordered logic:
  • If Age ≥60 yr, AgeFactor = -3
  • Else if Age ≥50 yr, AgeFactor = -2
  • Else AgeFactor = 0.
• PaCO2Factor is assigned values by this ordered logic:
  • If PaCO₂ ≥75 mmHg, PaCO2Factor = -1
  • Else PaCO2Factor = 0.
• PeakInspiratoryPressureFactor is assigned values by this ordered logic:
  • If Peak Inspiratory Pressure ≥42 cmH2O, PeakInspiratoryPressureFactor = -1
  • Else PeakInspiratoryPressureFactor = 0.
• Equation parameters such as On Ventilator Prior To ECMO, have two or more discrete values that may be used in the calculation. The numbers in the parentheses, e.g. (3), represent the values that will be used.
