For example, 16 events over 8 hours is AHI of 2. People like us not on CPAP have events of 20, 50 or 80 AHI. Our machines provide enough pressure to keep the airway open and reduce what is called obstructive sleep apnea events.

The drawback of using a simple AHI score is it records all events as equal. i.e. a 12 second stop is the same as a 40 second stop. Many of us look at our data to check on the length of time of our events. AHI is a major indicator, but not the only data we look at.
