What does FIO2 stand for?

Explanation:
FIO2 stands for Fractional Inspired Oxygen—the proportion of oxygen in the gas that a patient breathes. It describes how much of the inspired air is oxygen, not the total amount of gas or a description of the device. Room air contains about 21% oxygen (FiO2 ≈ 0.21), and supplemental oxygen raises this fraction toward 1.0 (100%) depending on the delivery method and flow. This term is used to quantify and adjust how much oxygen is being delivered to the patient. The other phrases are not standard terminology for describing the oxygen content of inspired air.
