oxygenation index

Abbreviation: OI
A measure of the efficiency of oxygen exchange by the lungs. The index is used in critical care medicine to assess the severity of acute lung injury and to gauge the effectiveness of ventilator management strategies. Mathematically it is represented as the product of the fractional concentration of inspired oxygen and the mean airway pressure, divided by the arterial oxygen concentration.

The parameters in CPIS such as WBC, temperature, and oxygenation index also showed obvious improvements, demonstrating that the addition of AA facilitated the infection control of VAP.
There were also significant inverse correlations between the oxygenation index and plasma levels of IL-6 (P = 0.
