New Hose; 28.5 AHI!

[gregger]

Hi all,

Relatively new (less than 1 month!) user here. My machine and I have been doing good; I started using the Phillips Dreamwear nasal cushion, but nasal congestion of late has forced me into the same brand's new full face mask which fits to the same type frame. That forced me to up the humidity, which forced me to go to a ClimateLine hose.

So I installed the new hose last night (borrowing the click-fit fitting for Dreamwear from the old hose to the new), checked it out, set machine to Full Mask, and went to sleep around midnight. 

Sleep report on machine shows I used it for 2-1/4 hours. I was awakened at 5 by my wife who said I was snoring and to roll over! I was quite surprised to find I had removed the mask in my sleep, I guess at 2:15 a.m. or so.

I put the mask back on and when to sleep until morning. My sleep report showed a total of 4:50 in usage time, Good mask seal, 3 mask on/off, and 28.5 EVENTS PER HOUR (vs my average to date of less than 5!!)

I don't have time this weekend to download and analyze Sleepyhead, but that's the goal. In the meantime, can anyone answer the question, what might have cause the machine to record 28.5 events?? If the number is 'real' then...did something change dramatically by addin a ClimateLine hose? It's a slim hose and I didn't check settings to see if it automatically switched the hose setting (my other hose is "Normal") but even then I can't imagine a slimmer hose trashing my therapy entirely.

Any ideas welcomed, and yes, I will download and run Sleepyhead on the data next week if I can. Thanks.

We need to see some data.  Just a SWAG, but how about a large enough leak that it brought you 80% awake and you ripped off your mask in annoyance?

If you have sleepyhead software, please download your charts and post images of them here so that we can see whatha got in the way of evidence.

I don't think I would make a lot of it just on one nights usage. That's a super high number but obviously it wasn't a typical night I don't think. If you keep scoring numbers like that, you should become very concerned.

Did you use the mask test feature? When I use that feature I get a ridiculous AHI. It jerks pressure all over the place and records events like crazy.

The machine doesn't record events during the mask test.

Look at your CA index. I can't use a heated hose because it elevates my CA index.

Explain this mess that I got when fitting my F20 then. At some point I may have stopped the mask fit, but from what I can see it recorded garbage through the whole time. I don't believe I slept a wink.

Mask pressure tests at the maximum pressure set. In your case that was 12.6cm. As you can see on your chart after the mask test is completed the pressure goes to your minimum starting pressure and starts to record data. Your mask pressure test had nothing to do with the data displayed.

Regardless the end result was to record garbage and give a false AHI. It bypassed my normal auto ramp where no events are recorded while you are awake.

That wasn't the mask test fault. That was poor planning on your part. All you had to do is turn off the machine once you tested the mask and than restart it.
