Nasal pillows that don't rebreathe?

[ProfessorB]

Hi, folks. I've been trying out different kinds of masks & and I've been trying the Pilario nasal pillows mask for the last few nights after trying a number of different nasal masks and fullface masks. The pillows are so superior for me that I'm really anxious to make them work. Here's the problem: unlike with the other kinds of masks, I'm having trouble falling asleep because the air seems too warm and feels as if it's rebreathed air. I don't know if that's actually the case, or if it's just in my head, but I do wonder if the relatively small volume of air in the pillows contributes to the problem. Does anyone know of a nasal pillow mask that might be less likely to give me this sensation?

I use a Resmed S9, no ramp, auto from 8.5-20, EPR set at 1, humidifier with the temp turned lower than room temp so no heating, just passover.

I've never used them but I know the design you're using. I am very sensitive to the same thing and find the P10 to be the most open even if I breathe deep and hard it never gets hot or "sticky". The big vents seem to help a lot and they weight nothing. They are very popular here.

I have used the Pilairo along with at least trying the bulk of the nasal pillow masks out there.
Never had the issue you are describing with any of the nasal pillow masks.
All I know is you will just need to try one (or more) of the other nasal pillow masks to see if the smaller space in those pillows offer less chance of the air staying warm because the venting moves the exhaled air out a little faster. Quicker exchange with the venting maybe because the volume in general is less.

here's a trick. put your hand by the vent, if you're using the diffuser, you have to be pretty close. you should feel the air coming out, between breaths and while inhaling, you'll feel cooler air being vented, when you exhale, you'll feel it warm up and then cool down again, when you don't feel the warmer air anymore, it's flushed it all out.

remember, too, that at your start pressure of 8.5, it's venting about 27 liters of air per minute, so it's flushing out the air pretty quickly
