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
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)
inspired oxygen concentration | 20% partial pressure of arterial oxygen | 90 mmHg (millimeters of mercury) mean airway pressure | 25 cm WC (centimeters of water column)
