FiO2 Mean Airway Pressure MAP PaO2 Oxygenation Index OI Explanation and Clinical Context Oxygenation Index is a validated measure used to quantify the severity of hypoxic respiratory failure and to evaluate the degree of ventilatory support required to maintain adequate oxygenation. The formula incorporates the fraction of inspired oxygen with mean airway pressure and arterial oxygen tension which allows clinicians t
