État: clinical-review-pending
Version de la méthode: Conventional oxygenation-index arithmetic v1: OI = (FiO2 [fraction] × ventilator-reported mean airway pressure [cmH2O] × 100) / arterial PaO2 [mmHg]. FiO2 accepts an explicitly tagged fraction or percent and is normalized to a fraction. The output is a raw, unrounded numeric index with no severity band or threshold
Population: Invasively mechanically ventilated patients for whom source-population applicability has been independently established. The equation is established in neonatal and pediatric critical care and has been studied observationally in intubated adults. Delivered FiO2, ventilator-reported mean airway pressure, and arterial PaO2 must be contemporaneous steady-state measurements from one documented ventilation time point, with arterial-sample identity, units, measurement quality, and timing verified.
Limites et exclusions: Noninvasive respiratory support; no ventilator-reported mean airway pressure; transient desaturation or changing-support measurements; non-contemporaneous values; or unverified ventilation mode, delivered FiO2, ventilator accuracy, arterial-sample identity, units, measurement quality, or documentation timing. · SpO2, capillary PO2, or venous PO2 substituted for arterial PaO2; oxygen saturation index or another saturation-based equation; inferred FiO2 or mean airway pressure; or population-specific interpretation not independently established. · Any severity band, cutoff, threshold, ECMO or intubation decision, diagnosis, prognostic or mortality claim, monitoring schedule, treatment, management, or other clinical decision.
