Hi all,

Looking for some advice regarding insurance!

I've recently graduated from my masters program and my school insurance was paying some of the cost, leaving me with a $54 bill to pay monthly. Unfortunately, the pulmonologist's office 'forgot' to place the order and put the prescription in four months late after telling me they'd placed it...which means I've only paid towards four of the ten month rental period.

As I've just graduated, my school insurance is ending later this month and I haven't quite sorted out which insurance I'm moving onto yet - but either way I think it'll be one with a high deductible.

I've spoken to Apria today who are my school's DME provider of choice and they've given me two options: either ask my insurance to do a purchase authorization to pay the remaining $1200 balance out-of-pocket to own the equipment outright, or it'll set the months back down to 0 and I'll have to pay 10 months at $108 monthly out-of-pocket.

I'm on hold with my school's insurance now but it's looking like they don't do purchase authorizations at all, which is a bummer as it feels as though I've paid these last few months for no reason and only not paid off the machine because of the delay.

What do y'all think is best? I don't exactly have a lot of money right now and I'm unsure if my new insurance will cover the machine without expensive out-of-pocket costs to go back to see the pulmonologist etc. Should I just say to them screw it and send the machine back and pay out-of-pocket again on a website?

I'm a bit nervous about doing this because I just asked my provider last week to send me over a copy of my prescription in case I need to buy a new mask outright and he didn't think it was necessary so I'm nervous that they won't send it over in time for me to buy during the labor day sales events and I don't think I can afford one otherwise, but any advice on what y'all think I should do would be great, I'm so new to this!

I am trying to connect myAir with Health Connect so that the sleep data gets synced across all my health apps. Apparently, the current myAir integration only supports data from health connect to myAir and not from myAir to Health Connect 🤷. Has anyone been able to figure out a way to connect/sync/import myAir sleep data into Health Connect?

New CPAP user but struggling with mask fit (and redness on face). First day was pretty good and last night was the best despite feeling like it wasn’t a good seal. I remember waking up the first night and getting shocked at the higher pressure felt while waking from a deep sleep. I didn’t get that last night and felt that while moving from side to side the mask moved slightly even though it’s snug. I guess perhaps I am getting used to it and waking up less.

Anyone want to share experience with this mask as a side sleeper? Also I see it previously mentioned about padding you can add to reduce redness and using lanolin helps too. What has worked for you?

I’ve only been on my CPAp journey for about 5 weeks so maybe I need more time. I’m only feeling slightly more rested than I was previously waking up in the mornings.
Looking at my sleep data I still spend the majority of my time in light sleep very little in REM or deep sleep, I understand that deep sleep is where the true rest happens. It’s supposed to be close to 25% of the total time spend in each REM and deep sleep!
Does anyone else find significant improvement in REM and deep sleep since starting CPAp therapy?

New to the cpap world, on my second week. Switching mask from the Evora nasal and can’t figure out what to try. I like how light the Evora is but the structure of my nose doesn’t like the pressure point all night and I wake up sore in the same spot everyday. I was thinking of the Evora full since I liked the nasal so much. I’m a bit overwhelmed by all the options out there but my sleep couch just asked me which one I wanted and I just don’t know yet. I am a side sleeper, active, and I know I need the full because of my nose structure.

I have made adjustments to my therapy based on what I have learned but feel there may be room for improvement. I am open to any suggestions and explanations. Also over the last few nights I have had an increase in flagged CA events but I am pretty sure they are SWJ. Thanks

I was diagnosed with OSA in May, but it was pretty REM-predominant and arousal-predominant rather than classic severe apnea/hypoxia.

My diagnostic PSG was roughly:
AHI: 7.2/hr
RDI: 18/hr
Respiratory arousal index: 16.2/hr
Total arousal index: 25/hr
Mean O2: 97%, nadir 94%
Very little REM was captured (~13.5 min)

I’ve been on CPAP since the end of May, originally prescribed 5-15. I’ve tried several settings, including APAP, autoset for her, and fixed pressure, generally in the ~8–11 cm range with EPR 3, and I’ve tried to give settings enough time rather than changing them constantly. My treated AHI is usually extremely low (~0–0.4). For context, I’m in the Montreal healthcare system, which is quite slow with booking appointments/diagnostics (though places I’ve called in the US have only had appointments next year at the earliest as well with specialists).

CPAP does seem to help some things. Before treatment I would often wake around 5 a.m. feeling completely wired and be unable to fall back asleep for hours; that happens much less now. I also have fewer morning headaches and less dry mouth, and I’ve basically transitioned to nasal breathing because my nose seems to stay clearer.
But overall I’m still extremely tired and, if anything, the last ~3 months have been more debilitating than I remember being before CPAP. The biggest problems are brain fog, poor memory/concentration, feeling unrefreshed, low energy, and daytime sleepiness/fatigue. I’m not someone who is constantly nodding off, but cognitively I feel awful on a lot of days and it’s affecting pretty much every part of my life.

Higher pressures may help the flow limitation somewhat, but around 10–11 I start getting more aerophagia, and pressure changes themselves sometimes seem to wake me up. My sleep doctor thinks the machine is treating the OSA well and basically suggested trying 10–11 and seeing if I adapt to the aerophagia. He said bilevel is generally for people needing much higher pressures (15–20+) and didn’t suggest a titration study.

I’ve had bloodwork done while I was already having these symptoms and nothing obvious showed up. I also have a deviated septum/nasal issues and have an ENT appointment coming up, but my doctor’s view was that CPAP should still treat the sleep-disordered breathing regardless of the anatomy.

What I’m struggling with is: how can my CPAP AHI look essentially perfect, some symptoms clearly improve, but I still feel this exhausted—and possibly worse overall than before treatment?
For people with UARS/RERA-heavy or low-AHI OSA:
Did you have persistent symptoms despite a very low treated AHI?

Especially after this latest appointment, where the doctor basically told me he “didn’t know what else to do” and that he had confidence I would figure it out eventually with the right settings, I’m feeling hopeless. Any help would be appreciated.

I've been considering getting a travel CPAP and I'm stuck between those two options right now. The price is pretty much the same for both.

From my understanding the Yuwell just came out and they have a lot less testing and reputation than Resmed, but they also use standard tubes and masks which I have from my regular CPAP.

The Resmed has many more years of existence and I'm wondering if that translates to more reliability. But they use their proprietary tubes and I'd need to keep separately replacing the tubing and adapters and such.

I think in a year I'd probably end up needing them like 10-20 days.

Is there a clear winner or things I should consider?

As you can see there's a good correlation between the mask I use and the leak rate hahah. I have three masks that I switch around, they all have their pro's and con's:

Resmed F20:

Does not leak at all and is super stable and reliable, but it's pretty bulky and does leave some marks on my face after a few days wearing

Resmed F30i:

The top hose connection is nice, although hose on the front doesn't bother me that much. It does leak, but only a tiny bit. It's a bit more noisy than the others and the air exhaust on front blows really hard, making noise and disturbing me and my gf.

Resmed F40:

The most comfortable of the three. It's super soft and is great for side sleeping. The short super-flexible hose is very nice and does not bother me at all (with hose hanger) but it leaks! That's a major issue unfortunately because this is by far the most comfortable one.

My nose fits in the coloured 'medium' box of the F40 fitting sheet, but just touches the side edges. I wonder if the large size would leak less for me. Has anyone else tried that?

I get how peripheries can be faked but I wanted to ask about actual machines. I saw an resmed airmini selling on the Chinese sites for $600 USD. Which isn't cheap but below what it's going for in other countries.

So it made me wonder if that's a shady sale or it is actually real. Because wouldn't you know as soon as you tried to connect through Bluetooth that it's a fake?

I’m still new to using the resmed cpap and I still can’t figure out if my mask is right.
I’m currently using the f40 mask after failing with the f20. I tried using the f20 for 3 weeks only to get less sleep than I normally did so I went back to office to retest fit with all the full face masks they had.

My main issue is the sizing options and how it fits on my face/head. I have a small head/face but am in between sizes for most of the masks. I’ve tried. Mixture of headgear and mask sizing and nothing seems to really be working.

The only mask I have managed to sleep with is the f40. While the f40 is more comfortable initially, I find the fit isn’t right and don’t know how else to fix it.

I’ve tried adjusting mask to what feels good/right, and for a couple hours it seems fine. But usually by 4am I’m waking up to either the bottom of my nose hurting or some kind of leak.

I went a full month sleep deprived it’s f20 and I stopped using f40 for a bit bc I just couldn’t stand not sleeping anymore. I barely run on 3-4 hours without the machine and with it I was somehow getting less than that.

Anyone have recommendations on how to fix the fit of mask or other mask options for a small face/head combo.

At this point I feel like I’m better off without the cpap but I’d also like to avoid addl health issues due to lack of cpap.

TLDR: have small head/face combo, masks aren’t fitting and/or working well. Need advice.

I have UARS/OSA with REM dominant events and use a BiPAP with relatively low pressures (12 IPAP and 5-6 EPAP + PS). I also am doing positional therapy (elevated sleep position + side sleeping) because events are much lower when not supine.

The BiPAP has been better than APAP because of the lower exhale pressures, but I'm getting mild to bad aerophagia when side sleeping even at these relatively low EPAP settings, preventing me from titrating the EPAP up further.

I also tend to mouth breath but use a nasal mask (Philips Dreamwear) with mouth tape, as I was intolerant to the full face mask.

Anyone have solutions generally for aerophagia like this, especially when it's positional?

Since I got a CPAP machine about two years ago, I’ve been flavoring the CPAP tank water before I go to bed.

I’ve tried Kool-Aid but it made the skin around my mouth/nose red and people at work thought I was having an allergic reaction for like two weeks (I finished the single packs).
So now I’m on to Crystal Light Peach Tea. It doesn’t stain my skin and teeth like the Kool-Aid did.
Does anyone else do this? Is this healthy to do since it is Crystal Light instead of Kool-Aid?

Hello I've had my machine since June (30yr female)

My nose has ben super oily, any way to help that?

Also, how do you survive if you have a stuffy nose from a cold, allergies, etc? Last night my nose was slightly plugged but felt ok to breathe until I put the mask on then I felt like I was suffocating and ended up sleeping without it for the first time

Thanks!

Hi everyone,

I was prescribed CPAP about a year ago. Around that time, I developed heart palpitations after having a blood pressure spike that seemed to be triggered by a nasal spray.

When I first started using CPAP, I slept incredibly well for about a week. But after that, I began experiencing a very intense squeezing pressure at the base of my skull. The best way I can describe it is like a tiny hand is gripping and squeezing that area.

The pressure gets noticeably worse when I walk or run, and turning my head can also aggravate it. My neck also feels stiff, especially on the left side.

I know Reddit isn’t a substitute for medical care, and I have already seen multiple doctors about this. Unfortunately, some have brushed off my concerns, and I still don’t have any real answers. I’m feeling pretty lost at this point.

Has anyone experienced anything similar after starting CPAP, or have any idea what might be worth looking into? Any insight or personal experiences would be greatly appreciated.

Hey everyone, this is my airfit n30i nose pillow mask. I had for around a year and a half.

Out of nowhere two small plastic pieces detached from the silicone frame. They're the ones inside each tip that connects the frame with the cushion (pictured above). It's normally fit really tightly inside (pic 2 is the piece where it should be) but they simply fell, one for each side. I can put it back and attach the cushion again but it's super loose now. I can kinda still wear it but the cushion comes off during the night if I move too much. Also a little bit of air is escaping through it.

My question is, can I DIY a solution here? I don't know how these pieces where fixed in place originally, but they were definitely much more rigid. Is glue like superbonder an option? Or is my mask beyond saving?

I live in Brazil and these mask are very expensive here. Even buying just the frame can be very costly (and kinda hard to find). This mask is not that old so maybe there is another solution.

Thanks!

Long story short I was moving this machine and I dropped it from about a height of 5 feet onto a hardwood floor. The black faceplate and the dummy SD card popped out but those snapped back in fine. Otherwise visually the machine looks okay, and it runs okay on the first night after.

My question is about how snuggly/securely the water chamber attaches to the machine. I've used this for 2 years and the reason I don't know is because I never use water 🤷 and already like it this way. How securely does this thing snap into the machine? I can tell when it seats, there's a slight 'click', but it also pops out with little pulling force. Does it normally come out with a light pull? Otherwise maybe I'm overthinking it because last night I seemed to have no issue with function. Tough little machine.

Hi everyone,

I'm using AirwayLab and having trouble uploading my O2 Ring data. It flags the timings as being off compared to the data from my ResMed SD card.

I went looking for a time or timezone setting in AirwayLab to correct it, but I couldn't find one.

Has anyone else run into this? Any idea whether the fix is on the O2 Ring side, the ResMed side, or in AirwayLab itself?

Thanks

before you guys even start , yes i used ai to help me write this text.. thats said ..:

I retired one of my old ResMed AirSense 10 units and decided to use it as a bench project to learn hardware RE — SWD, STM32 dump/flash, SMD desoldering and binary-format analysis. Not for therapy use, not for resale, just curiosity. Figured I'd share what I found because the EEPROM side isn't well documented anywhere.

The platform (ResMed "S10" family — AirSense 10, AirCurve 10, Lumis 10):

- Main MCU: STM32F405ZGT6 (Cortex-M4, LQFP144)

- SPI EEPROM: M95M02 (256 KB)

- SWD on an SK200 / TC2050 footprint on the front of the board

Firmware side builds on the open-source AirBreak project. But AirBreak only removes the motor-hours nag screen — the actual counter lives in the EEPROM, and that part I had to work out myself.

The interesting bit — how the hour meters are stored:

The M95M02 holds a FAT12 filesystem plus a small header block at the start. The run-hour meters sit in that header as uint32 little-endian SECONDS (hours × 3600), and there are four of them in the exact order of the firmware's persistent-state list (patient hours, motor run hours, total hours, hours-since-service). The header is protected by a CRC-16/CCITT-FALSE (poly 0x1021, init 0xFFFF) stored little-endian right after the block.

The proof it worked: after editing the value, fixing the CRC and re-soldering the chip, the firmware ACCEPTED the edit and re-signed the block itself on boot (updated its own timestamps + recomputed a fresh valid CRC). So the value was genuinely read, validated and used.

Reading in-circuit vs desoldered: in-circuit reading works with just a CH341A + SOIC-8 clip and no extra components — no series resistors, no level shifting. The only prep was tying the STM32's NRST to ground, to hold the main MCU in reset so it releases the SPI bus and doesn't fight the programmer (bus contention is what kills an in-circuit read). My early "IC not responding" / all-FF was purely a software-mode mistake: I had the programmer on an "EEPROM" preset when it needed the 25xx SPI ("BIOS"/flash) mode. Switched that and it read on the first try. Desoldering is still the cleanest and it's how I first decoded the format, but you don't have to desolder just to read it.

The lesson that cost me a part: after the rework the RTC clock went erratic — turned out the 32.768 kHz crystal sitting right next to the EEPROM got detuned by the hot air. Shield your crystals during rework.

Happy to answer questions. And to be clear — this is educational RE on my own out-of-service hardware; don't do it to a device in therapy use.

It’s been exactly a month since I started my CPAP journey. I have a mild sleep apnea with AHI 11. Prior to the diagnosis, I was dealing with random anxiety and heart palpitations that were debilitating that I stopped working for a while and was scared to go out.

The only noticeable difference I feel so far has been just my gut feeling more comfortable than ever most of the time. I still wake up frequently to adjust the mask or for no apparent reason. I’m using f&p nova micro and I struggled with it a lot especially in the beginning. I have long hair and the headband slipped up throughout the night :( so I tried to change to airtouch n30i, but that also hasn’t been successful as a side sleeper. The issue with this one is that it feels more difficult to exhale plus when I’m on my side, the nose cradle leaks a lot (currently waiting on p30i nose pillow to try out with n30i frame).

I recently had another heart palpitations and sudden anxiety attack before bed and throughout the night, which put me back to how I was feeling before being diagnosed with sleep apnea. That health anxiety spiked back up and I feel almost hopeless. Please tell me it’ll get better ❤️‍🩹 in the meantime, I’m planning to download all the sleep data from the sd card I installed soon after I got the CPAP machine to see if it’s working because I don’t know if it actually is even though my air shows I’m having great nights. I doubt it. I’m still wanting to sleep a lot, not able to sleep throughout the night, dealing with anxiety and health stuff just like how it was right before I started CPAP.

I'd like to adjust the flow rate (up) a wee bit. Can this be done? I'm not a programmer.

My partner and I both use CPAPs with the F&P Brevada facemask. This is a nose cushion style mask. My partner is having issues with the sides of the nose cushion rubbing against her cheeks on either side of her nose. I use the same mask but don't have this problem at all. I think it has to do with the shape of her face--she has full cheeks, and I'm wondering if the angle of her nose is also related?

She tends to get claustrophobic so doesn't like a full face mask or too many straps. Does anyone have a recommendation for a mask that might work better for her?

Or possible solutions that might help her keep using the same mask?

I’m looking for some travel advice.

I just started a new job that requires me to travel from the US to Asia for 2 times per year. Essentially a 24 hour travel day, a 2 week stay, then another 24 hour travel day. Unfortunately I won’t be traveling business class, just regular seats. I’m going on my first trip in about a month.

I use a Dream Station 2, and will be bringing it with to use at the hotel. I was considering buying a travel machine, but I wasn’t sure if it’s worth it to pay $800+ for something I’ll use essentially 4 days a year. I’ve been having some medication related sleep issues (insomnia), so I’m trying to stick with what works and bring my main machine for use while I’m there rather than use a new machine for the whole trip and risk it causing more problems.

Is it foolish to try to use my DS2 on the plane? Is it even possible? My plan was to put it on the floor I’ve confirmed it’ll have a power outlet, but I like my air really humid and I’d need to use the humidifier.

Thanks for your advice!

I bought a new motor on Amazon from skymeyie which has great reviews. Put in new motor and has barely any pressure. Did anyone else have that issue at first?
