Oxygenation Index Calculator
A precise tool.
What is the Oxygenation Index Calculator & How does it work?
The Oxygenation Index (OI) is a measure used in critical care medicine to assess the adequacy of oxygen delivery to tissues. It helps healthcare providers evaluate the effectiveness of mechanical ventilation and guide treatment decisions.
OI is calculated using the formula: [ OI = frac{FiO_2}{PaO_2} times 100 ], where ( FiO_2 ) is the inspired fraction of oxygen and ( PaO_2 ) is the partial pressure of arterial oxygen.
OI is calculated using the formula: [ OI = frac{FiO_2}{PaO_2} times 100 ], where ( FiO_2 ) is the inspired fraction of oxygen and ( PaO_2 ) is the partial pressure of arterial oxygen.
OI = frac{FiO_2}{PaO_2} times 100
FI( O_2 ) = Inspired Fraction of Oxygen
P( aO_2 ) = Partial Pressure of Arterial Oxygen
P( aO_2 ) = Partial Pressure of Arterial Oxygen

Frequently Asked Questions
What is the Oxygenation Index used for?
The Oxygenation Index (OI) is used in critical care to assess oxygen delivery adequacy and guide mechanical ventilation treatment decisions.
How do I calculate the Oxygenation Index?
To calculate OI, divide the inspired fraction of oxygen (FiO2) by the partial pressure of arterial oxygen (PaO2), then multiply by 100.
What does a high Oxygenation Index indicate?
A high Oxygenation Index indicates that more oxygen is being delivered relative to the blood’s ability to carry it, which may suggest inadequate oxygenation or ventilation.
Can the Oxygenation Index be used in non-critical settings?
While OI is primarily used in critical care, it can provide insights into respiratory function in other medical settings as well.
What are normal values for the Oxygenation Index?
Normal OI values vary depending on the patient’s condition and age but generally range from 100 to 200. Lower values indicate better oxygenation.
