So will turning it up to warmer temp make it more prone to condensation due to diff in temp?

Or would turning the temp down keep the condensation from forming?
Condensation happens when the air containing the moisture cools and can no longer hold onto the water.

Warmer air can hold more water than cooler air.

You need to increase the hose air temp when you want to prevent condensation.

The goal is to keep the air warmer when it leaves the heated hose section and travels up any short hose to the mask so that by the time the air gets to the mask it is still warm enough to hold onto the moisture it has in it and not release it because that's when you get condensation.

So when you warm up the heated hose temp then the air leaving the heated hose has a running start on hopefully being warm enough to not release the moisture as it cools down a bit.
This is why I was saying insulate the short hose with more insulating material and/or some sort of insulation around the mask itself. It will help the air retain more warmth which in turn lessens the chance of the air cooling to the point of releasing the moisture.

Excellent explainer thank you. Tonight’s experiment will be to turn the temperature up on the hose little bit and hopefully have my soundest night sleep in a long time. Thank you.

Anyone know what temp the hose is when set on auto?

Not sure if I should set on 80 or wherever?

I laid on my back for about an hour with N30 right before getting up for day and first time I ever had moisture in there on auto hose temp setting.

I may be wrong, but I believe that when the AS11 ClimitLine Hose Temp is set to auto, is intended to maintain the humidity level at 86% humidity.

wouldn’t the point of auto be to adjust automatically to ambient room conditions?

Soo.....it looks like the pressure ranges are pretty good. I believe I have had the best nights sleep last night that I have had in years and years. Pleasantly, I did not have to get up and go to the bathroom multiple times. When I got up the first time and looked at my watch I realized I had 7.5 hours of practically unbroken sleep and was thrilled.

That said, I put on a new N30 and a freshly washed/tighter strap. I thought I was getting a good seal but when I went back to bed after waking the first time I felt like it was leaking at every breath. Luckily by then I felt very well rested and just sort of laid there with eyes closed.

Ignoring those last segments and looking at the big chunk of R&R, IF anyone is willing, could you please look at this chart? I have questions.

https://sleephq.com/public/1f2cec6b-5f4 ... 7e6f927682

When you look at the pressure spikes, and then look at the flow rate charts that correspond, it seems like there are a few times that maybe SHOULD have been marked as an event but were not. I am wondering if anyone might offer some clue perhaps please? ie see: 11:30 and 11:40 ish where the pressure goes up Was it that maybe it was only 8-9 seconds and not the requisite ten to qualify as an event? How bad is the leak rate that occurs around that time? Hard to tell if the pressure going up is in response to a leak or an actual event or if it is a chicken/egg (leak created lower pressure which allowed for an event, but it didn't make it a full 10 seconds and wasnt an actual event?)

And are the marked events real? I see a decent sized breath (1:18:01) right before the first marked OA (5 seconds later)?

My hope is to become sophisticated enough to read these on my own so I don't have to ask.

Thanks to any who are willing to share or provide input.

Umm.... am I seeing a bug in SleepHQ? From my part of the world, it looks like you went to sleep at 04:23 AM. And there was a break at 11:30AM or so.

It is and it does. It makes sure that no matter what the ambient room conditions are, you'll have no more and no less than 86% humidity. The percentage is affected by the room temp and the humidifier temp. An auto setting means the machine varies the humidifier temperature with the aim of keeping the percentage of humidity in the air stable.

Well THATS weird.

When I clicked the link it showed I went to bed around 9:22 which is really 10:22 because the only way to fix the time zone setting will erase the data and I am hoping at daylight savings it will be correct.

I don't know if this is the same link but I just created it? https://sleephq.com/public/0ea121b4-147 ... 2f710d3a9b

Ooooh *I* see. Thanks!

Wires crossed there. Whoops!

The 01:18 ish flagged OA I would put in the "maybe real" basket. It's iffy. Tiny bit of arousal breathing right before the flag and a tiny bit of maybe recovery breaths afterwards.
This is what I mean when I say that sometimes we just can't always tell for sure or not. As a matter of what to do with "maybes"...I put them in the "real" basket when I don't know for sure just as a matter of extra caution.

As for the 11:30 to 11:40 time frame .....I see nothing that even comes close to being a flagged event based on the criteria.
10 second duration....80 to 100% reduction for the OA flag
or 40 to 80% reduction for the hyponea flag.

The tiny bit of pressure increase at 11:38 I would blame the little bit of flow limitation I see for that.
Don't forget that the machine will respond with increased pressure to snores and Flow limitations as well.
It was a tiny FL and a tiny pressure increase anyway.

Pugsy, are you seeing the sleep times the way lynninj reported them? I see them according to my own time zone, not hers --

Pugsy is a time zone over from me.

I was kind of using the spikes in pressure as the reference points and was hesitant to use the 11:30 11:40 times. If you look at the early spikes in pressure, I don't know what time zone or what time it says but that is specifically what I was looking at.

I think pugsy might have been too but I just dont know now.

I thought I saw a setting on sleephq that would allow for time changes but kinda don't want to mess it up? Not sure it would work.

Now I am quoting myself.

Seeing quite a few weird computer glitches including some with my other programs.

Time to run the antivirus.

Two hours after you went to sleep a flow limitation caused your machine to raise the pressure.

As I understand it, at 1:18:01 your time you took a deep breath, then stopped breathing or rather you tried to take one - you can the exhalations becoming shallower just before that (01:51:17), the breathing a bit ragged I think that event was an OA that couldn't be prevented.

Hmmmm ok. Thanks. I am trying to learn the subtleties here and I don't think I ever even looked or considered exhalations in the past. I guess you would just follow the pressures at the peaks and valleys to note the "shallowness" of the breaths?

Thanks for that so far folks! Really appreciate it.

Hmmmm...I dunno. I see what appears to be 8 PM to about 5 AM times recorded and what OP mentioned happening at 01:18 I also see at 01:18.

I have never done the sleephq thing myself and I really don't look at the starting and ending times all that much because hours slept is hours slept no matter what the clock might say. I have zero ideas how it does anything or why you see a different time zone thing.

OP is in NJ and I am in MO which is one hour difference yet what I see at 01:18 and she sees at 01:18 seems to match up.

I am no help. I had no idea that the times would/could be different.
