We have developed a method of recording oxygen saturation over time using ambulatory equipment. A pulse oximeter was modified to be powered by battery, and values for oxygen saturation were recorded by an analog recorder. The unit is compact and functions for 30 hours between battery changes. The mean difference between oxygen saturation reported by the pulse oximeter and an IL 282 CO-oximeter was -1.12 percent, with a range of difference +/- 2.75 percent, indicating 95 percent confidence… CONTINUE READING
