WebThis relationship can be altered by many factors (e.g. temperature, FDG, pH) but generally follows the classic “S-shape” graph with PaO2 on the x axis and oxygen saturation on the y axis. This online calculator can be used to convert SpO2 to PaO2. References: Lifebox Pulse Oximetry Learning Module; Oxygen Calculator Website WebThe calculation of nasal cannula FiO2 is rather easy. For the most part, just add 4 for each liter of O2. We would obviously do this above room air (21%). The only exception to this rule is the first liter (you add 3) – consider this a favor done to get you onto numbers divisible by 4. So, this is how it goes: We hope you’re seeing the pattern!

However, several mathematical models have … Web5 jul. 2024 · How do you calculate expected pO2? PaO2 should = FiO2 x 500 (e.g. 0.21 x 500 = 105 mmHg) How do you calculate PaO2 from SpO2? 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.
