The PaO2/FiO2 index quantifies the relationship between arterial oxygen tension and available oxygen concentrations.
Typically the RSBI is greater than 104, the MIP is greater than 20 and the PaO2/FiO2 ration is greater than 300.
Within 2 hours, the average PaO2/FiO2 significantly increased from 64 mmHg to 120 mmHg while PaCO2 significantly decreased from 63 mmHg to 33 mmHg.
A rapid and sustained rise in PaO2/FiO2, as well as a rapid and sustained decrease in PaCO2 and normalization of pH resulted in a more protective ventilation strategy.

Ratio quantifies the ratio of oxygen available vs.
When you want to calculate oxygen tension based indices such as the A-a Gradient, PAO2/PaO2 ratio or PaO2/FIO2 ratio the non-corrected results should be used.
Oxygen contents, Shunt fraction and oxygenation assessments using the A-a Gradient, PAO2/PaO2, or the PaO2/FIO2 should use the non-corrected results.
This phenomenon of improved paO2/FiO2 ratio, resulting from relatively higher alveolar pressure during inspiration, attracted the interest of the Bear Company.
We chose to select patients with paO2/FiO2 ratios below 300 for this study, analogous to the ARDSnet study.
For each patient, the paO2/FiO2 ratios were averaged in AC-VC.
The standard deviation was computed for the AC-VC data and for the VAPS (PAM) data in five steps: a) The difference of each paO2/FiO2 value from the paO2/FiO2 mean (average) was computed; b) Each difference was then squared; c) The squares were then added together as a sum; d) The sum was then divided by the number of paO2/FiO2 values minus 1 (n-1); and, e) The square root of this value is the standard deviation (S.
