Formula for Oxygenation Index?

Oxygenation index is calculated as OI = MAP × Fio2 × 100 / Pao2, where MAP indicates mean airway pressure and Fio2 indicates fraction of inspired oxygen.

How do you calculate oxygen index?

Oxygenation index is calculated by the following equation: mean airway pressure MAP (in cmH2O) × FiO2 × 100 ÷ PaO2. There are several disadvantages to the use of OI in the NICU. It is invasive and requires an indwelling arterial line or arterial puncture to obtain a blood gas sample.

What does oxygen index tell you?

The oxygenation index is a calculation used in intensive care medicine to measure the fraction of inspired oxygen (FiO2) and its usage within the body. A lower oxygenation index is better - this can be inferred by the equation itself.
