WebFeb 6, 2024 · The curve also shows that O2 sat falls slower than the PaO2–a change in PaO2 from 96 to 70 may only show up as a change in O2 sat from 97% to 92%. FiO2 can also affect an ABG reading. The PaO2 on your ABG should equal FiO2 x 500. If it doesn’t, there’s probably an A-a gradient. The PaO2/FiO2 ratio (or P/F ratio) is useful for categorizing ... WebHypoxemia is low levels of oxygen in your blood. It causes symptoms like headache, difficulty breathing, rapid heart rate and bluish skin. Many heart and lung conditions put you at risk for hypoxemia. It can also happen at high altitudes. Hypoxemia can be life-threatening.
