Readings (AHI)
I am new to all of this so please bear with me. On my readings for my nights sleep, it shows my events to be anywhere from 0.2-1. What does the 0.? mean? I understand that 1 = 1 apnea event 2 = 2 apnea events etc., but that does the 0.? mean.

RE: Readings
The AHI is averaged based on the hours of sleep. So you could easily end up with a fraction of a number.
From the Wiki: The Apnea-Hypopnea Index (AHI) is used as a measure of the severity of the condition known as sleep apnea. The AHI is the sum of the number of apneas (pauses in breathing) plus the number of hypopneas (periods of shallow breathing) that occur, on average, each hour. To count in the index apneas and hypopneas, collectively called events, must have a duration of at least 10 seconds. The AHI, as with the separate Apnea Index and Hypopnea Index, is calculated by dividing the number of events by the number of hours of sleep.

RE: Readings (AHI)
Maths. AHI is apnea events (obstructive and central) plus hypopneas divided by time. It would be an easy thing to have 0.2 events because it is the average.
