Silent and smooth breathing vs. rough and strained

I have been using a ResMed AirSense 10 Augoset device with a Swift Fx Nasal Pillow for several months now. Sometimes I put it on and everything's fine. The air flows smoothly in and out of the pillow... quite quietly almost like I wasn't wearing it.

Other times, I put it on and I feel like I'm having trouble getting enough air out of it and it's noisy. It hisses. Don't understand what could cause the difference. I'm not congested... I keep the air in the room consistently humidified with a humidifier. I have the ramp set to 45...

But why would the same system work one way one day and completely different another?

Any insights would be appreciated:)

I hope someone has an answer for you because I do not. The only thing is if the hose was kinked (which you would notice) or the air flow isn't adjusting as it should.

I was thinking a tensed day vs a relaxed day, just enough to alter your face shape, or perhaps a different sleep position.

You will have day to day variations and it always good to take that into consideration when altering settings. In otherwords, perhaps your settings are not optimized for you.

In the past someone suggested it could be humidifier slightly loose. Shove it in firmly until it catches. Could the hose coming out of CPAP be not pushed in snugly? Let us know what fixes it.

My ramp function is always turned off because I used to feel like I was suffocating if it was on.

Even so I often have the issues you seem to be describing.

I usually have to reseat the pillows a few times to get it flowing right and even then the slightest shift will make it noisy even when it doesn't seem to be leaking.

It seems dependent on perfect alignment and even strap tension all round.

I suspect that it also depends on full inflation of the nose and sinuses which sometimes requires a conscious effort to widen the airways.

This is the element that can fluctuate wildly from day to day but once proper inflation is achieved and stabilised the air pressure will sustain it.

Hopefully.

I generally sleep on my side but if I am having difficulties with the gear I force myself to start off on my back because it's easier to get it working properly that way.

By the time I instinctively shift to my side it has either stabilised or I am beyond caring. :)

What's worked for me with Resmed F30 full face: Switch on humidifier for a few minutes, put the mask on, feel slight airflow, select "mask fit", which gives big airflow and a red or green smiley face, fiddle with mask until it settles and smiles green consistently, then start sleep session. Listen and move fingers around outside of mask for leakage. Take out my hearing aids and don't have noise! (slight advantage for me) ;-)

If the mask is too tight it can crush the nasal pillow cone which can make noise and make it harder to breathe. I also find with the Swift the exhaust flow has a very high velocity. If it blows against the bed covers or clothing it can make a lot of noise.
