Changing flow limitations
#1
Changing flow limitations
I have a lot of flow limitations which require the pressure increase  to compensate.
BUT
The big question is why does the amount of flow limitations change from night to night. 
Same body,same mask, same pillow , same pressure range so why should they change.
All I can think of is diet.
Im thinking of having the same evening meal every night, boring, to see if the FL,s stabilise
Any other ideas why they should be changing?

Post a few OSCAR charts and either I or someone else may be able to help you with your question.

RE: Changing flow limitations
How much are your flow limitations changing?  Could be nothing more than a stuffy nose or perhaps your sleep position.   Mine have changed from 0.10 to 0.02 in a recent seven day period with with the same machine settings.

RE: Changing flow limitations
My flow limitations also fluctuate. It’s usually because of a stuffy nose. I’m most likely trying to suck air and the resistance is probably recording those struggles. ( just a guess) . The days I sleep good I wake up with clear sinus. ( that’s my theory)

The range  can be between 0.20 & 0.28 which does not sound much but there is about 5cm difference in pressure

Cpap is not perfect every night. Our charts may fluctuate. The quest is to work on our sleep hygiene and give us the best possible nights sleep with the aid of cpap. Cpap is just part of the solution.

RE: Changing flow limitations
OSCAR charts would help. I've seen no attached OSCAR chart in any of your threads, which means we lack some important info to help.

Another thread you have said there's a nasal polyp needing removed. Have you got that done?
