How to Interpret Airset Autoset S10 for Her Report

[dorisw]

I have been using my new Airset Autoset S10 for Her for 5 day now, and my husband has bough the same machine. I was questioning the Dr. but he said not to get hung up on the "For Her", the machine would be O.K. for my husband too who was keen on getting a new machine too without having to do a sleep study since our last one was three years ago and we did not want to do a sleep over under the present conditions. .... . Hubby has been using it for two days. This morning I scrolled through our reports but could not quite understand them.
For today my pressure was 8.6. I was a bit surprised, because my sleep reports and pressure setting on the other machines over the years were always around 5 or 6. But three years have past and things change, so O.K. Leak :0 L /min, AHL 0.0, Total Al 0.0, Central Al 0.0. Does this mean that last night I had no apneas at all ? And was it because the machine was doing a perfect job and preventing them ?
Over the last 5 days my pressure was 8.8, leak 2L/min, AHL 0.2, Total AL 0.2, Central Al 0.1 If zero is less than one, then how can I have a fraction of an apnea event?

For today my husband's pressure was 9.8 ( his previous machine was set to 9, so he is within his range). Leak 25L/min, AHL 9.4, Total Al 8.7, Central Al 7.4
The mask reading gave us a smiley face, so what is this about the leak and all the apneas? And were the apneas not prevented because of leakage ? We both just bought new Airfit P30i nasal pillow masks and thought they fit well. However he switched over to the the L mask ( always used M masks of other brands before) because he thought there was more noise being generated with the M size mask.
Over the 2 days of usage his pressure was 9.7, Leak 29L/min, AHL 6.9, Total Al 6.2, Central Al 5.1. Again, I do not understand that although the average leakage was higher over the 2 day period, there were less average apneas...
Our machines are set in airplane mode by choice, we had agreed to send a report to the CPAP healthcare provider in about a month, but perhaps we need to do something sooner?
Would greatly appreciate some insights.

The AHI numbers aren't total event numbers but instead an hourly index or average. So that's how you can see a fraction of an event.

The leak numbers and the pressure numbers on the machine are what we call 95% numbers...they are NOT averages.
The definition for any 95% number is where we were at OR BELOW for 95% of the night. 95% numbers are also easily skewed to the high side with just a relatively brief amount of time spent higher.

5 % of the night you were higher. We don't know how much higher though....you would need to use available software to get more details and see just how things might have gone.

Thanks, but I really wanted to understand if we should be concerned about my husband's leakage and apneas ? Although the mask seemed to be O.K., his leaks were 25L/min, AHL 9.4, Total Al 8.7, Central Al 7.4. Is this normal ? In comparison to mine, as I already posted above, I show no leakage, no Al.

I would need to see the actual detail reports.
The leaks for your husband I wouldn't worry about 25 L/min 95% number but the AHI is worrisome especially since the bulk of the AHI is central apneas.
A lot depends on when they are flagged ....like if they were flagged maybe while awake or not.
If he was asleep when they were flagged and if he was using EPR exhale relief we might consider reducing or turning off EPR and see if they reduce.
So there are a lot of factors potentially involved...but I wouldn't be happy with that number of central apneas per hour if I was for sure I was asleep. Now if he isn't sleeping well then those centrals might be false positives and we worry more about the why not sleeping well and fix that problem first and then see how many centrals he is having once the sleeping problem is dealt with.

Is your husband on any medication that might suppress respiration? Pain pills specifically????
Does he have any history of congestive heart failure issues?

The AHI is too high but sometimes we can explain away part of it by blaming awake false positive flags....
Need to see detailed reports to get an idea when they were flagged to start with as it might point to awake breathing irregularities.
Flagged events to matter we have to be asleep first.

The leak number...not so problematic unless the leaks are causing wake ups.
