Heated CPAP Tube ClimateLineAir for Resmed S10 AutoSet

Hi guys,
Is Heated CPAP Tube ClimateLineAir for Resmed S10 AutoSet a good choice?
I'm currently using SlimLine that comes with S10 and humidity in 6, but what is happening is next:

I can have both nostrils completely unclogged, but as soon as I lie down, one of them gets blocked. I'm even using a magnetic nasal dilator, which has helped a bit. It's always one nostril or the other, and in the middle of the night, they sometimes alternate, and the blocked one clears and the other gets blocked. I wondered if buying this heated tube might help, since I know you can control its temperature or keep it on automatic, letting the tube control its own temperature and humidity. Do you recommend buying it? If so, is it better to leave it on automatic or manually set the tube's temperature and humidity?

Thanks a lot as usual

This is normal. See --->

The nasal cycle is a physiological process where the nasal passages alternate between congestion and decongestion. This cycle helps to maintain healthy nasal function and protect the respiratory system.
Mechanism:
The nasal turbinates, which are spongy tissues in the nasal passages, become engorged with blood on one side.
This engorgement causes the nasal passage to become congested, leading to reduced airflow and mucus production.
After a few hours, the turbinates on the congested side shrink and the nasal passage opens up.
Meanwhile, the turbinates on the previously decongested side become engorged, starting the cycle again.

It might, and it might not. With CPAP humidity effectiveness, there is no formula. There is a wide range in how people's nasal airways respond. Trial and error often is the only way to find the sweet spot.

Have your nasal airways been getting dry? If not, too much humidity sometimes makes congestion worse. You could experiment with turning your humidity setting down a point per night to see if the congestion improves without causing nasal dryness.

I'm wondering if your machine pressure is set high enough to "blow through" the alternating congestion. Would you be able to create a free account at SleepHQ.com, upload the data from your machine's SD card, and then post the link to your SleepHQ account in this thread? If we can view your data, we might be able to offer some additional help.

Hey,

Thanks for the detailed asnwer. Here is the requestet link from SleepHQÇ https://sleephq.com/public/teams/share_ ... _id=eAqAVo
Thanks in advance!

You had a lot of arousals between 5 - 7 AM. Was the congestion bothering you then?

Here is what I would do ----->

1. As mentioned before, you could experiment with turning your humidity setting down a point per night to see if the congestion improves without causing nasal dryness.

2. Personally, I would turn the minimum pressure to 10 to see if it "blows through" the alternating congestion. After I pulled the mask off this morning, I lay in bed for a while and immediately noticed congestion in both nostrils. But I hadn't noticed any congestion while using CPAP because the pressure was keeping both nostrils open.

3. Unless there is a good reason why your maximum pressure setting is 11, I would change it to 20. The machine will not go any higher than needed.

If you change the pressure settings and humidity settings at the same time and conditions improve, you won't know which caused the improvement. So, you might want to experiment with one first and the other later.

Great. Let me try decreasing humidity first. If it didn't help, I'll check pressure. Thanks a lot for your time and analysis.

Having one nostril blocked isn't necessarily a problem, if you can get enough air through the other.

My out-of-date browser won't show me your SleepHQ info, and even if it did I'm a newbie at looking at CPAP squiggles. But from what I've heard, if the tops of the squiggles are flat-ish (of outright flat) it means you're not getting as much air flow as you should, and if they're round to a little pointy it means you are. (Some software will tell you, but not the one I have.) So if you're flow-limited whenever one nostril is blocked, that's a reason to try to get them both open.

A piece of advice I've heard and liked is to use the machine when you're awake, while you're trying to learn what's going on. If wide-awake-you is breathing easily when the squiggles look a particular way, and annoyingly congested when they look another way, that might be helpful for interpreting the squiggles from fast-asleep-you.

For myself, I like the maximum humidification that my machine will provide. But I can easily imagine that an even higher humidity level would be too much.

I like the maximum humidification

The range is no humidifier (me) to maximum (you).
