Conversion of spo2 to pao2
WebDec 10, 2024 · How do you convert SpO2 to pO2? Example: Suppose a patient on 40% oxygen has a pulse oximetry SpO2 of 95%. Referring to the Table above, SpO2 of 95% is equal to a pO2 of 80mmHg. The P/F ratio = 80 divided by 0.40 = 200. What is normal pO2 on pulse oximeter? The brain gets affected when the SpO2 level falls below 80-85%. WebFeb 9, 2024 · Let's say our patient has PaO2 = 95 mmHg, which is a healthy value (between 75-100 mmHg), and has a FiO2 = 30 % (so this patient is most likely receiving oxygen-enriched air). PaO₂ / FiO₂ = PF ratio. 95 …
