About Oxygen Saturation Index
The Oxygen Saturation Index (OSI) is a measure used to assess the oxygenation status of patients, particularly in critical care settings. It's calculated as:
OSI = (Mean Airway Pressure × FiO₂ × 100) / PaO₂
Lower values indicate better oxygenation, while higher values suggest more severe oxygen impairment.
