Compute Oxygenation Index (OI) for a mean airway pressure of 15 cmH2O, FiO2 of 0.60, and PaO2 of 90 mmHg.

Oxygenation Index shows how well oxygen is being transferred given the level of ventilatory support, and it uses MAP, FiO2, and PaO2 in its calculation: OI = (MAP × FiO2 × 100) / PaO2. Plugging in the values: MAP is 15 cmH2O, FiO2 is 0.60, PaO2 is 90 mmHg. Compute 15 × 0.60 = 9; 9 × 100 = 900; 900 ÷ 90 = 10. So the Oxygenation Index is 10. Higher numbers indicate worse oxygenation or greater support needed.
