Problems with airflow for Resmed P10

By this time it should be obvious that I don't use the P10.

So... the vent mesh is in the frame. It seems strange that the vent mesh is collecting more "dirt" than the main machine filter. Would a change to a hypoallergeric filter help keep the vent mesh clear?

Dirt aside the other issue is rain out. If water drops plug the vent mesh I guess you have to be on high alert for rain out. I have never experienced rain out so I am not sure what a solution would be. Does this mean that I have "mastered" CPAP use, or that I just live and travel in an areas that are not conducive to producing the environment needed for rain out...?

I like it here. Don't you guys EVER change. Freedom of speech will set you free.

I wonder what mdmarmd would think to discover that there are people out there that have a differing opinion than s/he does... prolly call 'em toxic or something else.

I've been on the p10 for three or four years now, I do use a hypoallergenic filter, plus an antibacterial inline filter (it seems to help keep my allergies at bay while sleeping), and I've never had a problem with the vent mesh clogging.

Cruft does come out of your lungs while breathing though, so the supply air isn't the entirety of the equation.

Well... crap in the lungs is hard to filter.

Roughly how long does your P10 frame last?

I looked at the P10 but ended up with the Brevida. I have not had any issues with its filter plugging up in spite of using it for over a year. Perhaps it has a different filter construction.

I wonder what a psychologist would call a person who left other sites to come to this site and try to turn it into the site they left.
Just a toxic persons opinion.

Mines over a year old just clean it when I think about it monthly or so

Saw the "other forum" had a thread some doc sleep apnea sufferer that uses a p10 made - shows what the vents of the p10 caused. I cant seem to find a great replacement for the p10 yet

This is a very real problem, despite the efforts of some here to belittle it. I personally encountered it. Fortunately I was able to solve it by dialing back the humidity. Look in the "safe" forum at this post of mine where I previously responded to mdmarmd when he raised the issue there.

The graphs show how my airflow was very very affected by the blocked vents. I don't know why I didn't wake up, it was pretty bad!

It's very very important to keep the vents open for the Airfit P10.

I love my P10 but I'd gladly trade a little more noise for bigger vents. But I want it done by the vendor, I don't want to try to poke my own holes in the mesh.

It's very very important to keep the vents open for every CPAP mask.

FTFY.

The P10 is definitely more prone to blockage than other masks, which I suspect is why Resmed’s subsequent products don’t have P10-style venting.

I found the soak-and-toothbrush routine just doesn’t keep the mesh clear. Blasting the mesh from both sides with a Waterpik at its highest setting does seem to be effective, but it’s an extra step that other masks don’t need. Actually, the P10’s the only mask that’s ever blocked up on me.

The P10 vents are AWESOME . . . There is nothing quieter.
I am not a clean freak, but I do not mind doing what is needed.
A water flosser (messy) or a denture tablet (minty) will do the trick.

Oh, come on. Of course that's true, but you're deliberately being obtuse or argumentative.

The design of the P10 makes it easy for the vents to get clogged. This doesn't happen with other masks. E.g. I used to have a Mirage Swift II, and while it was a fairly quiet mask, the vent holes were much bigger. It wasn't prone to clogging.

Making light of this problem is a dis-service to newbies and to people who aren't as attuned to the nuances of what's happening.

Implying that it's only important to keep the vents clear on the P10 is a disservice to newbies and people who aren't as attuned to the nuances of what's happening.

Vents on other masks can, and do get clogged, it happens, it's important to keep them *ALL* clear and functioning, no matter what axe you're currently interested in grinding.

EVIDENCE OF AIRFIT P10 VENT OBSTRUCTION CAUSING HYPERCAPNIA

For those still concerned about potential obstruction of P10 vents I am posting a few of my graphs that show measurements of an acute rise in intra-luminal CO2 in a P10 as it's vents completely obstruct.

You can see the full, detailed post at:

BTW: After returning to this site to see if there were other post regarding this problem with the P10, I was quite surprised to see how unkind and condescending some of the postings can be.

Didn't bother to read? It's in there.

What do you want them to do, put a plastic flag on the mask itself? like you find on electrical cords?

When was the last time you read one of those? The last Christmas lights I bought had *THREE* flags... I didn't read those either.

I don't have a "condescending attitude" with respect to this. You went on a rant. I pointed out that you admitted to not bothering to read the very instructions that you so vehemently indicated Resmed should have supplied. I'm sorry you didn't like being called on it.

What's truly sad is that you can't just own up to the fact that *you* screwed up.

I've seen three or four posts in the *years* since the P10 came out. None as
relentlessly whiny as yours, though.

Or in anther thread:

PLEASE stop posting your ignorance here.

I tried to find the forum rules that speak to decorum expected on the forum, and apparently there is next to none.

I did read that this is an unmoderated forum, which may be the reason an “anything goes” attitude is acceptable. Apparently, CPAP.com is not concerned enough to commit the resources to ensure that the forum they sponsor is a safe, and inviting educational site, especially for newbies. I suspect a lot of visitors are inhibited by the coarse responses and just stay as "lurkers", or move on to other sites.

I am apparently not alone in my, "whiny" view!

As a psychiatrist, I can say we have a name for individuals that manifest these features. We call them toxic people!

I would suggest the phrase, Offering all the warm fuzzies of the fictional Doctor House, MD should be retired.

Thanks for the effort and fwd of information mdmarmd!
Has been painfully obvious to me that the Resmed p20 has a design flaw..not the issue of the mask not working if the vents get dirty (which should be intuitively obvious), but instead the effect of humidity on venting and C02 build up. Myself? I don't use my p20 mask in the winter as my wife and I have a humidifier running in a small enclosed space (our bedroom). Been through two masks, both have the same issue. High humidity = mask breathing issues. Otherwise, the p20 is an exceptional mask.

Of interest to me, recently comparing my p20 mask with one that my brother owns, we both noted that the diffuser vents have been redesigned (feels smooth to the touch vs a gritty feel of the microvents). Perhaps the change is in part due to the high humidity venting issue? Talking to my DME and seeing comments here, it's obvious that I'm not the only one who has experienced the venting problem. The sad news is that Resmed does not highlight the issue and that we have people on chat boards who like to belittle others..perhaps the trials and tribulations of spending 24/7 on the board and now a curmudgeon.

Our interactions on this site has great value (especially to newbies) and providing advice is a great service. Yea, someone needs more of a life as he at times is pretty toxic (and obviously proud of it).
