WebJan 12, 2008 · The percentage of oxygen in the atmosphere does not change with altitude, so it is about 21% at 10 000 feet. What does change is the pressure. This declines with altitude. At sea level the air pressure is about 101 kPa (kilopascals). Oxygen accounts for 21% of this so the oxygen pressure is 19.6 kPa. This means that there are less oxygen … WebMar 27, 2024 · This tool uses a cutoff of 90% based on an elevation of 4226ft. The Math: Oxygen saturation can be calculated based on the Severinghaus equation which assumes a temperature of 37 degrees celcius, and pH of 7.4. [cite source=”pubmed”]35496 [/cite] The Severinghaus equation converts PaO2 to Oxygen saturation.
