Gils Guide To Encore Pro:
How to interpret and read Encore Pro software sleep data based on daily reading
1. Pressures the machine ran at that night Cu. cm. of water.
2. Min at pressure = the top line has the pressure the machine run at and the min of pressure show how many minutes the auto pap was at the above pressure on line #1 above. ( Mostly for reference only )
3. % of time that night the auto pap was at the above pressure on line #1 above. ( Mostly for reference only )
4. Flow Limitation - Partial closure of the upper airway, which impedes the flow of air into the lungs. See Notes below.
5. Snore = The Snore Index displays the total number of snoring events per night divided by the hours of use. This often correlates with the severity of airway obstruction and apnea. See Notes below.
Notes on 4 and 5 Above;
You'll see some hypopneas, apneas, limited flows and snores appearing on the Encore Pro software chart and graph. Those are events that happened despite the machine trying to keep them away. It is normal to have some. As long as the AHI (apnea/hypopnea index) stays below 5, the machine is doing its job.
6. Non-responsive apneas and hypopneas = Events the autopap did not resolve. The REMstar Auto algorithm looks for apnea’s that are non-responsive to treatment which could indicate that these are central events. However, it's normal for anyone to occasionally have a random "central" or two. That's true whether you have Obstructive Sleep Apnea and are on cpap treatment, or have no sleep apnea at all - a "normal" person. Even "normal" people occasionally have a random central from time to time during sleep. Nothing to worry about if they don't happen often and are scattered.
7. Obstructive Apnea - Repetitive cessation of breathing during sleep for 10 seconds or more due to complete closure (collapse) of the throat.
8. Hypopnea - Periodic, partial closure of the throat during sleep resulting in reduced air exchange. The medical consequences of this partial closure can be as severe as sleep apnea (full closure of throat)
9. Apnea index (AI) is defined as the number of apneic episodes/hour sleep.
10. Apnea-hypopnea index (AHI) is the total apneas plus hypopneas during total time asleep, divided by the number of hours asleep.
You also want to know how the AHI is divided between apneas and hypopneas, as the apneas probably have more effect regarding sleep arousals and oxygen levels than the hypopneas. The respiratory distress index (RDI) is the same as AHI. An RDI of 0 to 5 in normal; 5 to 20 is mild; 20 to 40 is moderate; over 40 is considered severe.
11. The RDI (respiratory disturbance index) includes apneas and hypopneas, and may also include other respiratory disturbances such as snoring arousals, hypoventilation episodes, desaturation events, etc. They are often identical, but depending upon what is scored, the RDI may be larger than the AHI.
12. The pressure level = Average pressure the Auto pap ran during the night like 5.4. The 90% number is the total number of hours the patient was at or below the shown pressure (8.7 cm in the sample report)
13. Air leakage = In equipment in Liters per minute. LL = Large leaks.
Not daily report but long term trend report below.
14. Auto Pap Time at pressure =The blue line indicates the closest pressure level to the 90% pressure level. This can be used as a guideline when prescribing therapy pressure settings
