WebAug 11, 2024 · Patient has a pulse oximetry SpO 2 of 95% on 40% oxygen: SpO 2 95% is equal to PaO 2 of 80mmHg. P/F ratio = 80 divided by 0.40 = 200. P/F ratio = 80 divided by 0.40 = 200. Although the patient may be stable and asymptomatic while receiving 40% oxygen, the patient still has severe acute respiratory failure. WebThere are a few reasons why the SpO2 can differ from the PaO2. Pulse oxygen can be less accurate for a few reasons such as hypothermia, poor perfusion states, and darker pigmented individuals. The software algorithms for SpO2 can also be less accurate with low SpO2 since you would have to place people in hypoxemic conditions to get reliable data.
