WebOxygen Desaturation (SpO2) – A drop in the level of oxygen present in the blood over a few seconds of time as a result of an apnea event or hypopnea event. People who do not have sleep apnea or any other breathing problems usually have oxygen levels that stay between 93-98% in their blood. Oxygen levels are considered abnormal when t hey fall WebThe oxygen desaturation index (ODI) is the number of times your blood oxygen falls for more than 10 seconds, divided by the number of sleep hours.

WebIn total, we analyzed 892 severe desaturations. The mean time from oxygen saturation peak to the oxygen saturation nadir (desaturation) was 43.6 (±3.8) seconds, whereas the mean time from oxygen saturation nadir to peak oxygen saturation (resaturation) was 14.0 (±6.9) seconds, thus taking one-third of the time as the desaturation episode. WebJan 1, 2005 · The ODI is the average number of oxygen desaturations at least 4% below baseline level per hour. Several studies have tried to determine the sensitivity and specificity of this method, with results ranging from sensitivity of 31% to 98% and specificity of 41% to 100%, depending on the specific devices and ODI cutoffs used ( 14, 15 ).
