Oxygenation Index Calculator
Calculate Oxygenation Index (OI) for mechanical ventilation severity
Critical Care Guidelines: The Oxygenation Index (OI) measures the severity of hypoxic respiratory failure and ventilatory support intensity. It is calculated as $(\text{MAP} \times \text{FiO}_2 \times 100) / \text{PaO}_2$. Enter ventilator and ABG parameters below.
