Funny I already had the Sound Meter app on my phone. I don't hear my machine or almost anything else at night though since I wear headphones with noise suppression. I had to change the notification for a work page so I could actually hear that as I was sleeping right through them. The only thing else I would hear is an actually phone call and the fire alarm.

The annoying beep has been significantly muted to the point it can just barely be heard.
Sleeprider wrote:I agree with one caveat. Too many new patients are issued auto machines with wide open settings starting at 4 cm. When they use EPR at 3 we often see huge clusters of OA, H and UA as a result of the inadequate EPAP
When they start at 4 minimum...there is no EPR at all no matter what the setting. EPR won't kick in until there is room for the exhale to drop.
Similar thing with the Respironis AFlex (not sure about CFlex but I would assume it would be the same) but AFlex simply won't do anything if the minimum pressure is below 6.0.

I agree about the importance of finding the optimal minimum pressure setting when using APAP mode...I had first hand experience with that myself when I first started therapy. 8 cm minimum didn't quite get the job done very well...9 was a little better but still had some ugly clustering...10 minimum worked like a champ and got me to 16 to 18 fast enough to get the job done in REM...Respironics M series machine. Never got the chance to try a ResMed at all until Rested Gal loaned me her S9 VPAP Auto so that I could compare it to the PR S1 750 I had at the time.

All in all I still say that it's pretty much a toss up between the 2 brands...both have minor pros and cons that the other doesn't have and they are only deal makers or breakers if a person happens to have a serious issue with whatever it is that might be a con.

I didn't have time to get the Adapt set up for hubby to help with experiment...I actually forgot until he announced he was going to bed. Will try to do that tomorrow and also get the decibel levels for the Adapt and eyeball the audio analyzer too. I had already taken the Adapt apart and cleaned everything and changed the filter and got it already for the next time it would be used.

Well...
Second night...I increased min EPAP 1 cm...took my meds like I am supposed to.
Lights out and I don't remember one wake up...7 hours or thereabouts.
Remember, I was working off the crappy night before so there's no way to logically put all this on the machine...I have done the same on the other machines but not very often. It's very rare that I have no memory of any wake ups but time will tell if this happens more often or just was one of my flukes....or the aliens felt sorry for me for letting the prior night go down and gave me some sort of "help" to sleep more solidly.

Subjectively I feel the same as I feel most other days after 7 hours of sleep even if slightly fragmented. The real test will be how I feel around 4 or 5 PM but that may not be a good test because mowing the yard is on the agenda today along with some serious work in my straw bale garden.

Haven't looked at the data yet. There's no big rush...it isn't going to change.
I have never ever been a morning person so can't use that as a guideline. I learned long ago that miracle was unlikely to ever happen.

I have a System One 50 series and can relate to the conductive inhale noise that you report.

I sleep with earplugs to avoid waking up if my wife has a mask leak so the conductive noise is about all I hear.

I have added my old Respironics Oasis pass-over humidifier downstream of the System One and it is an excellent muffler.

Probably not an option if you want the heated hose and it might hinder bipap operation as well.
For other S1 users this might be useful to know.

I added the Oasis to give me cooler air and it's worked well at that.

The inhale noise was less annoying last night when I first turned the machine...probably a combination of being so tired and I am adjusting to the sounds.
I did muffle the beep so it is barely there when I turn the machine on.

I don't know if adding a little more length to the circuit would have a negative effect on the machine or not. Supposedly we can use 10 ft hoses and adding another humidifier and a couple of short hose connections to the original 6 ft circuit could still keep us within that 10 ft limit.
One could still use the heated hose but that would mean the second humidifier was way down the line and some of the heat would of course get lost going through the second humidifier and subsequent short hose connections.

The inhale noise is not that much of a problem that I would feel the need to do this sort of fix. I mention the inhale noise because I can hear it but it isn't so loud that I can't go to sleep.
It's just there and I quickly tune it out so it really isn't an issue.
I had the same thing with the APAPs I have had so it isn't just the bipap's pressure changing on inhale and exhale.

I used both a ResMed S9 Adapt model 36037 and a PR autoSV model 960p for about a year... I'd have to agree with Pugsy's comments about how each generally approaches pressure response/therapy. Diggin' a little deeper into the setup menu, the breaths per minute feature (called BPM) is not for the fainthearted IMO, It's better to experiment with the default 'auto breath rate' first and seriously try to get that to work for you. Don't look for this feature in the Adapts because it doesn't exist in the S9 Series, I can't speak for the new Aircurves on this issue.

BTW, Pugsy mentioned the Q-tip trick for silencing the beeps early in this thread. Here's two replies plus a how-to picture I recently contributed on the topic... this trick works great but be sure follow the directions exactly (on the plus side, you don't have to open the case, hurray!).

I like my ResMed AirFit F10 FFM - reasonably low leaks for my ASV therapy. I'm currently using a PR S1 AutoSV 960P Advanced. I also keep a ResMed S9 Adapt as backup. I use a heated Hibernite hose. Still rockin' with Win 7 by using GWX to stop Win 10.

I compared the manuals for the s9 vpaps and the aircurves, and couldn't find any extra settings, or, indeed, anything that looked new and different, except the built in cell modems and the case around the guts.

I elected to just leave the BPM to auto and let the machine sort it out. So far I haven't experienced it wanting to do something that I didn't want to do.

The S9 is a proven reliable war horse, maybe the Airsense and Aircurve will get there one day, for now I'll stay with the S9.

Anxious to read about your trial. They are always informative as was Sleeprider's most recent postings when he got his latest.

I agree with what you guys were saying about the EPR and minimum pressures. You saved me from some ugly stuff at my start by suggesting I raise pressures to accomodate the EPR. Many thanks. I always worry to see it described as a comfort feature. It's a little bi-level and should be adjusted with much attention.

Can't wait to see how your new machine works on OSA in regard to user comfort.

Best,

Mike

Just a quick update on my progress with the 960.
Sleeping quite well with it and in fact got close to 10 hours on it Saturday night which is a total new landfall record for me. I never ever sleep that long.
Some dumb ass, who shall remain nameless, messed with the settings Sat and inadvertently set EPAP maximum to EPAP minimum and the result was also a total new landfall record but in a bad way in terms of AHI and it was all OAs and hyponeas. My fault though...don't know where my brain was.
But surprisingly I slept very well and felt quite decent yesterday so again...AHI isn't the whole story by a long shot.

Minimal wake ups or arousals as long as I take my meds which is what is supposed to happen..duh.
The inhale noise is fast disappearing just like the exhale noise on the Adapt disappeared at least from my conscious mind. I knew it would and that's why I wasn't worried about it. If I don't think about it I don't hear it.

Looks like the kinder gentler Respironics approach to things is going to mean a little more EPAP than I was getting by with when using the Adapt but not hugely more. Exact amount to yet be determined as I need more time invested in a setting to evaluate things.

All in all definitely a keeper for me as I am happy with it at this time.
It does use a lot more water than the Adapt and while I know that I am now using 90% humidity instead of 80% with the Adapt the amount of water used is a LOT more. One of these days I will set the 960 to 80 % and see how much it uses but right now my nose is so happy with almost snorting water that I don't really want to mess with things. No rain out in the heated hose or mask even with the cooler nights and windows open.

People will wonder which one I like better....I don't know that I have an answer at this time. Right now it's a toss up.

Snorting water will give you a different kind of breathing problem
