1. Usage hours
The system for usage is calculated in hours and minutes, as shown on the table below. The more time you use your therapy, the more points you receive, up to a maximum of 70 points.
2. Mask Seal
The better your mask seal, the more points you can get. This category can help you know if you need to adjust or change your mask to get a better fit. If your mask seal is poor, it can affect your comfort and the quality of your treatment. Your score reduces as your mask leak increases. You can get up to 20 points for minimal mask leak, 10 to 15 points for moderate leak, and 0 to 10 points for higher leak.
3. Events per Hour
This category is measured by the times while asleep you experience a apneas and hypopneas (AHI). These events indicate how that your lungs have stopped breathing in more than 10 seconds. If you have minimal events, you get 4 to 5 points.
4. Mask on/off
This category is rewarded by the least amount of time you remove your mask during sleep. The more you remove the lower the points are, the most points achievable is 5.
