In the desired FiO2 formula, which term represents the FiO2 that is currently known?

Explanation:
In this formula, the quantities are split into what you already know and what you’re trying to achieve. The FiO2 that is currently known is labeled as FiO2 known, because it represents the FiO2 value you already have measurements or settings for. This distinguishes it from FiO2 unknown (what you’re solving for) and from the targeted values like PaO2 desired (the goal) or PaO2 known (the current arterial oxygen pressure). So the term that represents the FiO2 you already know is FiO2 known.
