What does FiO2 (fraction of inspired oxygen) mean? Why is it called that way?

crvgrl - Simply put, if you take the air that someone is breathing and find out how much of it (percentage-wise) is oxygen, you get the FiO2.
The air around us is made up of 78.1% nitrogen, 20.9% oxygen, 0.9% argon and 0.1% carbon dioxide and other gases. Therefore, your FiO2 is 0.21 (21%). If someone in the hospital is on a breathing machine that is delivering pure 100% oxygen, then his/her FiO2 would be 1.00 (100%).
They named it such because, as you point out, it stands for "fraction of inspired oxygen". In other words, it is the "fraction" of the "inspired" air (inspire means to breathe in) that is made up of "oxygen", O2.

FIO2 is one of the parameters of a ventilator that measures the flow rate or percent of oxygen delivered or being received by the patient.The higher the rate the more oxygen consumption being used by the patient.
