I used one on a recent flight. I was at 12,500 feet with a density altitude of 15,800 feet. I was at altitude about 50 minutes when I took my oxygen saturation level. I was not on oxygen. It was 78% oxygen saturation. At that level, my decision making ability was impaired. Impairment starts below 90% saturation. I recommend the article. One point in the article is that with the unit, you can monitor the amount of oxygen really needed and whether or not you are getting enough from your tank. The unit that is battery operated, fits on your finger and gives a reading in about 45 seconds, costs about $400.
