Input interpretation
oxygen index
Equation
O_2I = (FiO_2 MAP)/PaO_2 | O_2I | oxygen index FiO_2 | inspired oxygen concentration PaO_2 | partial pressure of arterial oxygen MAP | mean airway pressure
Input values
inspired oxygen concentration | 20% partial pressure of arterial oxygen | 90 mmHg (millimeters of mercury) mean airway pressure | 25 cm WC (centimeters of water column)
Result
oxygen index | 4.1
