Need help with pulse ox data

While the chart shows 96%, there is actually a range that goes from 92 - 96%. At sea level the range is 94 - 98%.

Since the elevation translation is somewhat linear we can now look at the lower levels.

While sleeping at sea level the bottom saturation level is 88 - 90%. At 4700 feet elevation we can adjust that to 84 - 86%. Since the report indicates that the lowest level was 84%, he is within the general limits. If we were looking for a label we could call that "low normal."

Unfortunately the numbers only tell part of the story. What counts is how he feels. If he feels like crap at a minimum of 84% and feels much better at a minimum of 88% then additional oxygen will help. The "numbers" simply serve as a benchmark for further reference.

The real question is what is causing the lower saturation levels. Elevation is part of the answer. With a doctors help hopefully the rest of the answer can be uncovered.

Thanks to all for your input.
