Oxygenation Index (OI) Calculator

Mean Airway Pressure =
FiO2 =
PaO2 =
Oxygenation Index =

Help

Use to determine the oxygenation index - which is a numerical assessment of severity of respiratory distress in neonates. This value is often used to determine the need to proceed to extracoporeal membrane oxygenation (ECMO) support.

Rows

- Mean Airway Pressure: mean airway pressure in millimeters of mercury (mmHg)
- FiO2: the fraction of Inspired Oxygen Concentration in percent. Room air of 21%
- PaO2: partial pressure of arterial oxygen in millimeters of mercury (mmHg)
- Oxygenation Index: a numerical assessment of severity of respiratory distress in neonates.

Examples

The term newborn that you are caring for is requiring increasing mechanical ventilatory support. His mean airway pressure is 14. He is on 100% oxygen and has a PaO2 of 45. What is his Oxygenation Index? Input the following:
- Mean Airway Pressure: 14 mmHg
- FiO2: 100%
- PaO2: 45 mmHg
The calculator solves for Oxygenation Index giving an answer of 31.1.
