[CPAP] Rebreathing Issues

RE: Rebreathing Issues
3.
Unless your machine is a brick OSCAR will display detailed stats. Download it and try. Which specific model of S9 do you have?
2. Intended as a caution as well as a possible cause
1. If it has insufficient leakage you have a defective product.

RE: Rebreathing Issues
All consumer CPAP full face masks must have the AAV, anti-asphyxiation valve. Hospital use and some full face ventilator masks don't, as they can be designed different. This is an important note. And when present, the AAV is not your normal operation exhale vent.

The ring of vent holes under the QuietAir opaque ring are your vents for normal operation. Since we don't have laboratory testing, it's possible you're feeling some effects that this vent may be restricted slightly, but not completely blocked.

See my QuietAir review. Search Apnea Board for other threads and posted comments. I have cracked open the opaque ring and removed the glass pack muffler from the QuietAir. Mostly it was due to black spots on the white packing.

I use an AirFit F30. It performs just fine. I've often wondered where my exhaled air goes? If I place my hand around the elbow, I can't detect any air.  Dont-know

It must be magic!  Big Grin

RE: Rebreathing Issues
Another F30 user here perplexed by the magic Smile  Other masks I've used I would put my hand in front of the vents to figure out if it's on. With the F30 I can't find the vents and so I have to  pop up the corner to hear the leak!

The air has to be going somewhere, but darned if I can figure it out!

@Gideon:

Can the elbow for the Airtouch F20 be submerged in water for cleaning?  Will it damage the mesh if it's submerged in water?

RE: Rebreathing Issues
I've been cleaning all my face mask equipment (elbow included) submerged in hot water. Been doing this for three years now, and no issues or problems.

No, but the mesh should be dry before use

I wash mine once a week along with my hose. I used the first one 5 months until one of the little flaps broke. I'm certain the instructions said to wash it, but can't find my instructions.

RE: Rebreathing Issues
Would it be possible to submerge the mask in water while the CPAP machine is running? You should then be able to observe the bubbles, verifying that air is indeed escaping through the vent holes.
