This score ranges from 0-10, with a higher score meaning that the blood is the most saturated with oxygen (in other words, the higher your score on the range of 0-10, the better). It is a combined assessment of frequency, depth, and duration of drops in oxygen saturation.
O2 Score: the overall assessment of oxygen shortage throughout the recording session.Lowest SpO2: the lowest SpO2 reading gathered throughout the recording session.Average SpO2: overall average of your SpO2 readings gathered throughout the recording session.
If you have sleep apnea, you can also look at this as your Apnea Hypopnea Index (AHI). Drops per Hour: the average of the number of times your SpO2 decreased by 4% or more per hour throughout the recording session.Įssentially, this could be seen as the average number of times you experience notable oxygen desaturation per hour.Unless you changed the presets, these are the times when your pulse oximeter vibrated throughout the recording session to let you know your oxygen level dropped below normal range. These drops are indicated as the small white triangles at the bottom of the SpO2 graph.
Drops over 4%: the number of times your SpO2 decreased by 4% or more.In other words, from the time you put it on and start it to the time you take it off. Recording time: the length of time you used the pulse oximeter to collect readings.
