The fraction of inspired oxygen (FiO2) is the concentration of oxygen in the gas mixture. The gas mixture at room air has a fraction of inspired oxygen of 21% , meaning that the concentration of oxygen at room air is 21%. The percentage of oxygen at different altitudes remains the same, meaning the FiO2 of air in the atmosphere remains 21% irrespective of the altitude of an individual. [1]

When oxygen consumption and supply are mismatched, cell damage, and death occur.[5] . The key is recognizing the cause and, thus, the appropriate route of treatment. Inhaled atmospheric gas is 21% oxygen. The amount of oxygen inhaled, i.e., FiO2 is not equivalent to the oxygen which participates in gas exchange at the alveolar level.
What is the purpose of FiO2?
In the setting of critically ill patients, FiO2 is routinely used to assess the lungs' capacity for gas exchange. , using the PaO2/FiO2 (P/F) ratio, where PaO2 represents the partial pressure of oxygen.
What can affect FiO2?
Another factor that can alter FiO2 is humidity . Dry air, aside from being uncomfortable for patients, has the potential to increase airway resistance by inducing acute damage and inflammation. Dry air can also cause increased water loss and decreased mucociliary clearance.
What is the meaning of FiO2?
To understand FiO2, it is crucial to understand a few other terms: Hypoxemia: Is defined as a decrease in the partial pressure of oxygen in the blood. [2] PaO2: Partial pressure of oxygen of arterial as measured by an arterial blood gas sample. [3] PAO2: Partial pressure of oxygen of the alveoli, a calculated value.
Is FiO2 equivalent to oxygen?
The amount of oxygen inhaled, i.e., FiO2 is not equivalent to the oxygen which participates in gas exchange at the alveolar level . Several factors need merit consideration and are summarized by the alveolar gas equation. The equation takes into account the barometric pressure (P), water vapor pressure (P), and the gas exchange ratio (Rq).
