On a CPAP, obviously no, because higher pressures are being prescribed for people still. It might be the case for an APAP. It would be wise to talk to your specialist for a second opinion; yours and his/her’s.

if you are saying "no it’s not a no-no" then you don’t know enough to be giving advice on this subject. It’s acutally a big no-no because pressure set higher than your body likes can cause central apneas in people that wouldn’t other wise experience them – which are potentially worse than apneas. Check the archives on this group for the words "central apnea" and i’m sure you’ll find more detailed info on what i’m referring to. — Beth in Australia (I am not a medical professional and anything stated in my posts is my opinion only unless specified otherwise) =================== FAQ for alt.support.sleep-disorder can be found here http://talhost.net/sleep Newsgroup Archives http://talhost.net/sleep/archives.htm this site is a work in progress – feel free to submit info/articles

You’ve posted a different slant to what other people have been saying. I’ve been reading that pressures higher than 10 cause CAs in APAP’s. But checking google says that too high a pressure may cause central apnea, although central apnea is very rare. Personally, I think she should give up driving first, but as I said, talk to the sleep specialist for a 2nd opinion.

Hello all, I’ve used CPAP for about 4 years. I had a hard time getting adjusted to it, but now I can’t sleep without it. My initial setting was 6. I gained 40 pounds, had another sleep study, and it was set to 10. I gained another 37 pounds, had another sleep study and am waiting on the results. Meanwhile I set the pressure to 12 on my own. Is this a terrible no-no? What are the dangers of setting it too high? I will see the doctor and get the correct setting and maybe even have a DME set it (because I’m wondering if my machine is now getting old), but in the meantime, I’d like to sleep better. 12 seems better to me than 10. Also, no one told me to replace the mask once or twice a year. I did change it twice several years ago. My brother asked me if this mask or machine had any other uses, I said, yes, dog toy! That’s why I had the first two masks changed. Puppy grew up and we haven’t had that trouble since. Anyway, my mask cracked and leaked, etc after several years of use. I had duct tape on it at one point. That’s when I changed my settings to 12, to compensate for the leak. The new mask is definitely a big improvement, but I still like 12 better. Sarah

Yes. Big no-no. Look for references on "central apneas". Its due to the something-something reflex (sounds sort of like "herb braurer"). Especially when you get above pressures of 10cm. I would put it back and wait for your new prescription. -Quick

If you have a tendancy to gain (or lose) significant amounts of weight, insist your doc either put you on Auto titrating PAP or do a sleep study any time your weight changes by more than 10-20%. The AutoPap will adjust for your weight changes withhout an additional expensive study. As for masks, different models have different lifespans. The Breeze has a good comfort level, but I never could get one to survive 6 months.

Did you switch from the Respironics passive humidifier to something like an F&P? That could cause a pressure increase, your pump should have been reset to compensate for the difference. Tom – Sick of Spam? Join CAUCE. http://www.cauce.org

There’s a slight pressure drop as it goes through the heated humidifier. The manufacturers recommend setting it up as it will be used (humidifier or not). As to whether it makes any therapeutic difference, I don’t know. My engineers’ guess is that your typical F&P would have a pressure drop of less than a cm of water…. so you’d be probably be getting a bit more pressure without the humidifier. — On CPAP @ 15 cm since August 1998.

IIRC, there have been several mentions of a minor drop in pressure on some xPAP/ humidifier setups by the time it gets to the mask end. Ask your DME to come out and check if that may be the case with you. The pressure may not be much but it may be enough to go below the pressure you need to remove the blockages. You may also have a leak in one of the connections, but I’m sure you checked those already. — Magesteff - "Everything should be made as simple as possible, but not simpler."-Albert Einstein ——————————————————– Pursuant to US Code, Title 47, Chapter 5, Subchapter II,
