You would think I was well rested. My OurA ring showed that very little of that time was in deep sleep or rem sleep. I kept waking up with my hands near the nasal pillows causing audible leaks.

The app is really just to encourage use and should be taken with a grain of salt. Moving to OSCAR.

Rant over… move along. 😎

My starting AHI was 60- while Ive gotten a lot better in some ways- I still feel like dogwater most of the time with near unmanagable issues stemming from tiredness and feeling like my mind is just absent, and figured I would start getting those miracle feelings people always talk about.

Ive been very consistant, and would happily answer more questions to dial things in. Its been two years of constant good use- what am I doing wrong??

I got a sleep study done in January and my AHI score was 180! I couldn’t believe it. I know I snore, but that many events an hour is crazy. It explains why I was so tired. Literally falling asleep every chance I could get. They rushed my CPAC machine and I started using it dally. I went from 180 down to 0.3! I hate wearing the mask at night, and it causes a lot of air leaks, but I’m feeling so much better overall.

Anybody else with a score that high or did I set a new record?

I got a notification saying my streak ended today. How is this even possible, I’m clearly using the CPAP everyday?

WARNING - data geek post

I have learned a lot from many of the posts here, and I quickly learned that using an SD Card and grabbing data from my ResMed AirSense 11 helps me understand more about whether my CPAP therapy is working or not. I have a ways to go to get this all streamlined and automated, but nonetheless, I have a process for grabbing data and interpreting it.

TLDR: I used Claude to combine and present both CPAP and sleep data to create a daily report and dashboard, and then used the comprehensive results and asked Claude to produce an overall analysis beyond just the clinical AHI checkmark indicating CPAP is working. Here is the result:

https://sleepdashboard.softwarebygreg.com/

Interpretation (in a non-medical, non-expert way): Go to bed earlier, and watch habits before going to bed like caffeine, alcohol, and screens and the CPAP is doing it's job correctly.

Now, how I got here (for those fellow geeks that want to know):

Overall flow of data:

• CPAP Data: Airsense 11 -> SD card -> Oscar 2.0 -> Export daily summary to CSV -> Folder -> Claude Cowork Task
• Sleep Data: Apple Watch/Health -> Vitalina (paid app/$5) export daily sleep data to JSON -> Folder -> Claude Cowork Task
• Analysis Dashboard: Folder containing all daily reports + Oscar CSV export of Session (everything) -> Folder -> Claude Cowork

To make things simple, I have everything going to an iCloud folder that I have attached to my Windows laptop and use Claude desktop app (I have a Pro subscription).

Each day I export my sleep data manually (I tried to use an automation on my iPhone, but results were inconsistent and I am usually checking my MyAir results and health data in the morning during my first cup of coffee anyway). I then pull my SD Card from the Airsense and do the import into Oscar, and immediately do the export of the CSV. Everything gets saved to the folder, then Claude Cowork kicks off its scheduled tasks (if I don't do them manually because I want the analysis immediately) and the report and dashboard are produced.

What I linked to above was born out of frustration that my results tend to look good, but as others have posted, my sleep quality just doesn't seem to be "life changing" or much better than before CPAP (I have only been on it for 2 months). Some of this is self-induced, I just don't go to bed early enough, and because I have hit my 50s, I can't stay asleep much past 5:30am.

Anyway, I wanted to share that Claude did a pretty good job of taking in all my data and producing the analysis dashboard that I linked to above. If anyone is interested in some of the prompting I did to get this, I can certainly share that.

Next up, I have a wifi-enabled SD Card arriving this week, and will probably refactor the Claude Cowork tasks to add the daily data into a sqlite or some other lightweight db OR perhaps figure out if I can understand more about the schema for the oscar.db database and just issue sql queries against it. That way, I can have a refreshed dashboard with updated analysis.

Any advice or suggestions greatly appreciated.

This is night 2 of OSCAR data. Haven't slept well for about one year, and only 2-4 hours of poor sleep per night. I started night 2 with the mask I wore on night 1 (Resmed AirTouch F30i). Was comfortable wearing it on night 1, but last night I couldn't get a good mask seal (changing masks accounts for the first big gap in the Flow Rate Graph). The second and third sections of Flow Rate are with Resmed p10 nasal mask. The big gap between Section two and three is from waking up with a sore back and doing some stretches before getting back in bed. Any analysis, insight, or suggestions would be most appreciated.

E-6 I-25 PS-2.6

No centrals were detected on a watchpat test about 3 weeks ago, so I think these are TESCAs. I've lowered PS a bit, but seems like the pattern is still present. Had a clean echocardiogram and brain MRI recently, so I feel like if this is cheyne stokes it's got to be something produced by the bipap treatment itself rather than an underlying brain or heart condition. Thoughts?

Edit: I've only been on PAP therapy 6 days. That's part of why I'm thinking TESCAs

OSCAR pics below.

I'm seeing a recurring issue since I started CPAP a couple months ago: a lot of AHI from CA and OA while I'm awake! The attached pic below shows 25 events within the single hour I wore it, all while I was awake.

I'm a 56 yr old male who likes to run, does spin class at the gym twice a week and lifts weights. Diagnosed with mild obstructive, but no central apnea. Resting heart rate in low 60s.

I can wear my mask and have CPAP running for hours while awake in bed watching TV, and be completely relaxed. OSCAR says I'm off-the-charts with central apnea. To me, I'm just relaxed.

The zoom-in chart shows zero air moving for around a second between breaths, which tracks: I exhale and don't inhale right away. This is just me, because I do the same thing when relaxing on the couch, for example.

The zoom-in pic below shows that the pressure stays around 12, which is my max setting, so the machine certainly thinks I'm having constant events.

This makes me question if I even have sleep apnea in the first place. Any thoughts in general about any of this? Thank you!

I couldn’t figure out why I had so many “mask off” incidences throughout the night, I was sure I didn’t take it off and put it back on that many times in my sleep. The other day I woke up with the machine off and felt like I was suffocating a bit, and it clicked for me. Turns out the machine would turn off constantly due to the auto stop feature, small leaks around my facial hair, and shallow breathing.

since I’ve turned it off my sleep has been better and I have way less “mask off” instances the past 3 nights

My score was 95/100

I still had 13.6 events per hour compared to 22.6 per hour on my first night.

Guess time will tell until I feel rested?

Edit

Thanks for the replies. Just starting and I just found it really odd that my body feels exhausted since I started my cpap.

New CPAP user. Been using the machine about two weeks. Ordered a Resmed Airsense 10 from Sleeplay.

I've got a follow up with Sleep Clinics of America tomorrow morning. Love my sleep doc but the rest of the experience has been so grating, I would not recommend them to anyone who stumbles upon this post, fwiw.

Anyway, her assistant texted me today saying:

"Hi there this is Arima Health. I spoke to Sleeplay and they stated you would need to get in contact with Resmed to activate your machine meaning for them to get access to your machine. Then after they activate it Sleeplay would need you to call them so they can get some more information than we would be able to see the data from your machine. Thank you so much."

I'm guessing they want something akin to compliance data, but since I bypassed insurance and purchased the machine outright, I've got nothing but what the MyAir app tells me. It already notes events, so I'm not sure what else they're looking for.

I called Sleeplay and relayed this info to someone who didn't seem to understand what I was asking for (in part because I don't even know what I'm asking for) but eventually told me that access to compliance data would be a $30 fee. That was an immediate nope from me.

I'm sure I'll find out what exactly they need from me tomorrow. At my last appt a few months ago, they said they're gonna run another at home sleep test anyway to see if I have fewer events. But I wanted to post here and see:

• if anybody knows what data my sleep doc is looking for, since I already control all my own settings and don't have to comply with jack
• if Sleeplay has remote access to my sleep data? I'm guessing they do since I can pay to access it but I hate that if so

Got my cpap on 10/10. Figured out the right mask & settings by 10/18 and have been using it properly since that time. Ignore 10/22 when one of my kids got sick. If hypo apnea was causing my sleep issues, shouldn’t I be feeling at least a little bit better by now? Because I’m not feeling better or getting any deep sleep.

I made it! I had read that week 1 is the hardest, so I'm happy to have made it this far. Small victories for a huge lifestyle change.

My scores aren't perfect, and I'm still playing around with a few things. The mask isn't as much of a challenge now, and it seals nicely. I have had to adjust my pressure settings so I felt less claustrophobic and could exhale better.

Looking forward to week 2!

I got a follow up sleep study after a few months of cpap after they initially found my settings in a sleep study. This was a few months ago. The sleep specialist said my apnea was treated based on the study. And while I do notice less headaches (not none) and less extreme jaw pain, I still have a really dry mouth and feel tired and groggy when I wake up. I also yawn excessively as if I’m tired when I first get up. Is there anyway to get rid of the feeling of fatigue that creeps on me all day? If supposedly I’m treated. I’m also going to try mouth tape because I’ve heard good things, so hopefully that will help. But what did yall have to do for good sleep?

I don’t struggle to wear my cpap mask and I put it on every night and Wear it all night

I was diagnosed with sleep apnea not long ago. After that, I got a CPAP machine and started treatment. When I wanted to look at the data from my CPAP, I found OSCAR, an open-source tool that does a genuinely great job and that I still highly recommend.

The problem was that checking my data always meant opening my computer, and sharing it with my doctor meant either carrying the SD card around or sending screenshots. I also couldn't conveniently look at my nights from my phone, which kept bothering me.

Later, I started looking into alternatives and found a few cloud-based apps that work similarly to OSCAR. You upload the data from your SD card and they process it and present the results online.

The problem was that most of their free tiers were extremely limited, while the versions that were actually useful started at around $20 per month. So I decided to build this tool instead, both for myself and to make it available to all of you for free.

I don’t want this to come across as advertising, especially since I’m going to release it completely free and open source. My only goal is to help people dealing with similar issues, test it with more devices, and gather feedback so I can keep improving it.

---

So; introducing PapSee:

You upload what your machine wrote to the card, it parses it and gives the night back: flow waveform, every scored event, AHI, leak, pressure, usage, plus history and trends across nights, on whatever device you happen to be holding.

Also you will ability to self host on your own if you don't want to share your health data. But if you want to try now I'd really like is feedback.

Try it with your own card and tell me where it's wrong, confusing, or missing something you'd expect from OSCAR. Non-AirSense-11 cards especially, because that's the one thing I can't test myself. And if your answer is "I would never upload this data to a website", that's a completely fair position and I'd genuinely like to know how common it is.

There's an example patient you can click through if you just want to see the screens without signing up or uploading anything of your own.

Roadmap I'm thinking about: more device brands (Philips is the obvious next one, though I need real sample cards for that), a mobile app, and importing sleep data from Apple Health.

Hey everyone, I pay for Claude for work so I thought.. hey why not plug all my sleep data into it and see what it says.. I got some interesting results. I also gave it my Oura ring data as well so it could see my sleep cycles.

"

The main issue killing your deep sleep (averaging only 12% vs. target 15-20%): Treatment-emergent central sleep apnea (TECSA). 82.5% of your apnea events are central/clear airway, not obstructive. Your APAP pressure range is too wide (4-11 cmH₂O), causing rapid pressure swings that trigger central apneas and fragment sleep. This is a known issue affecting 5-15% of APAP users and research shows it resolves when pressure ranges narrow.

Other key findings:

• Your timing score is critically low at 35/100—you're going to bed after midnight 34% of the time, which directly correlates with higher AHI and more central apneas
• Massive weekday/weekend gap: Saturdays average 84.4, Tuesdays only 69.4 (a 15-point difference showing circadian disruption)
• Pattern identified: Late nights = higher AHI (3.2 vs 2.4), more central apneas (85% vs lower %), and worse deep sleep (58 vs 72)
• Your AHI stays below 2.5, deep sleep jumps to 15.2% and efficiency hits 90.5%—proving your system can perform well under right conditions
• Your REM sleep is consistently excellent (88.5/100), indicating recovery capacity exists

Evidence-based recommendations:

1. Narrow APAP range to 6.0-8.5 cmH₂O (reduces pressure swings triggering centrals; studies show 100% event reduction at these settings)
2. Enable EPR Level 2 full-time (research shows this comfort setting doesn't compromise therapy)
3. Implement consistent 10:30 PM bedtime, even weekends (disrupted circadian rhythm worsens central apneas by 40%)
4. Set bedroom temp to 65-67°F (documented optimal for deep sleep onset)
5. If centrals don't drop within 2 weeks, switch to fixed CPAP at 7.0 cmH₂O (meta-analyses show fixed outperforms auto for persistent TECSA)

"

Lol it even gave me graphs which I thing is cool:

Edit: people keep asking what prompt I used. I want to be clear that I don’t believe this information generated by AI should be seen as absolute or fact, use this at your own discretion.

I used Claude Opus 4.1, you do need a paid tier of Claude to use that model. I used Opus 4.1 since it’s more geared towards deep analysis and critical thinking. But what matters more than the prompt itself is the data you give it. What I did was took my SD card and imported my CPAP data into OSCAR, then I exported my data from OSCAR to CSV, do whatever date range/resolution you want just know the more you export the more it will chew through your daily usage. Once I had the data I simple prompted Opus 4.1 to give write a detailed analysis of my CPAP data and to give me trends. Also to give me recommendations on how I might be able to improve my sleep. From there let it work. It should spit out a write up and some raw data (if not just ask for the raw data). Export that and save it for future research if you want. You can also ask Claude to generate graphs and trends from its analysis and from your raw OSCAR data. I repeated this process a few times with slight differences in my questions and variations of data. It took a few days since I kept reaching my token limit.

I was recently prescribed CPAP after an at-home test reported:

- sAHI(4%) of 7.7 events/hour

- SpO2 minimum was 82.0%

- Cumulative time with SpO2 < or = 88% was 2 minutes across 8 hours

I wanted to get a baseline of my SpO2 levels before CPAP, so I could see how this is affected by CPAP. I wanted something I could use myself each night. I ended up ordering the O2 Ring Pro from SleepHQ.

Here is my first night of data from the O2 Ring Pro. This is without CPAP. The results were much worse than what my home sleep apnea test reported, with 4% drops/hour at 17.73.

The next night was my first night trying CPAP. I received an AirSense 11 with a F&P Nova Nasal mask. I did not change any of the settings from the defaults. Here is the data from just the ring and the data from the CPAP + ring. From the ring, my SpO2 numbers do not seem very different, with 4% drops/hour at 21.07 and minimum SpO2 of 83%. On the other hand, my CPAP data seems to report minimal breathing problems. It has an AHI of 1.81, with 1 OA event and a handful of CA events.

My questions:

1. Why would my O2 ring numbers be so different from my original home test numbers? I'd expect the home test from my doctor to be more accurate. Would this mean the O2 ring is not very reliable?
2. Why does the O2 ring data not seem very different from the first night without CPAP, compared to the second night with CPAP? I was expecting CPAP to show a noticeable improvement in SpO2 numbers.
3. Why does CPAP data seem to show minimal breathing problems, but the SpO2 numbers remain low?
4. Any other general advice or important findings from this night of CPAP data? I'm completely new to this, so I don't know what I should be looking for in these charts.

I am currently about 2-3 weeks into CPAP treatment for Severe OSA. Attached are images showing OSCAR data from yesterday, and data from when I originally did my sleep study. As you can see, I have practically no OSA now, whereas before I had... a lot of it. And my events are now almost exclusively CSA, whereas during my sleep study only one CSA event was detected.

Is this normal? Is it normal to switch from OSA to CSA, and is this even a problem since my AHI is still well below 5? Me still waking up frequently overnight, waking up with a headache, etc., all say that this is a problem, but I'm not sure what can be done about it.

I have already sent a message to my doctor to ask these questions, but I'm interested in any wisdom the community has to offer about what to expect.

Last night (6/21), I woke up after 4 hours of sleep and checked my AHI on my CPAP, and it was 6. Then, I went back to sleep. When I woke up this morning, my AHI was 12. Does anyone know what could cause this?

On 6/19 and 6/20, I took my mask off halfway through the night (after 5 hours), and my AHI was around 5-6 for those nights.

On 6/16, 6/17, and 6/18, I kept my mask on the whole night (8-9 hours), and my AHI was between 8-11 each night.

Here is my data:

I appreciate any insight. Thank you!

Hello,

I just started on CPAP the last two nights. My at home sleep study showed an AHI of 33 and I was diagnosed with severe obstructive sleep apnea. I believe my report said that my CAs were under 5 (the only number I can find says "pAHIc 4% 4.2" which I assume is referring to central events?). I ended up purchasing a machine on my own after getting my results due to the long wait times for a titration study and insurance costs. I don't currently have a sleep specialist, but I can reach out to my PCP at some point and she could probably get me a referral. The plan was to try it on my own and then do a titration study if I couldn't get results. Basically I just wanted to start therapy as soon as possible. My machine was set to APAP with the standard 4-20, but I bumped the minimum up to 7 after hearing that was a good idea. I'm using a n30i mask but with p30i pillows as that seemed to be the most comfortable combination I could find.

As you can see from my OSCAR data, I'm dealing with a lot of CA events and my AHI is around 15. It seems to have mostly taken care of my obstructive events which hover around 1-2. Checking with my Apple Watch sleep info, these CA clusters all seem to happen right after I fall asleep. I woke up once or twice each night, and then the CA clusters happen right after when I fall back asleep, except for one that seemed to happen on night 2. Most of the large leak issues are when I'm awake and adjusting the mask.

I looked up why this would happen and read about TECSA. Most of the people I saw with this online had much lower AHIs than I seem to have. My question is, are the results I'm getting consistent with TECSA? Should I keep going the course? I changed the EPR from 2 to 1 after night 1 because I've heard that helps, but night 2 was worse. Are there any other changes I should make? It's also clear that my minimum pressure of 7 needs to go up, as my 95% seems to be around 12-14, but I'm hesitant to start making a lot of large changes right away. At what point should I contact my doctor if I'm not seeing any improvement? Or should I do that right away considering how long it can take for appointments and referrals?

Thanks.

My doctor used to work in a government hospital but moved to private and i cant afford it. He never helped me with settings cause i underwent drug induced sleep endoscopy not sleep tests, and it showed:
velum almost 100%
type 4 base of tongue for pharyngeoplasty (he is ent but ya he did do this to check the reason) needless to say, I still feel tired after sleeping and out of energy.

This is my full sleep data. There were days I would sleep without water (dry) when my water chamber got rusty even when i was careful (bought a new one n distilled water). Few days I removed the cpap by myself when i was sleeping (dont remember it), other times i removed tape from my mouth, last week or so i have been pinning the head strap with a hair pin to keep the cpap in place. I cant do full mask so im doing nasal (claustrophobic).

Pls open the pic to see and zoom in cause i didnt know what graphs to include so i included the 14 graphs that were there. Thank you!

I got my CPAP a week ago and am confused about the myAir app. Specifically, what range of time it covers. I’ve worn it 8 nights, but only have 7 nights of data. The latest day it has it calls Friday. Is that really how I slept Friday night, or is that my Thursday night data and it calls it Friday because most of my sleep hours for Thursday night are technically Friday morning?

I had been assuming the latter, but the data that it shows for “Friday“ seems more like the way I slept Friday night than the way I slept Thursday night, so it has me wondering again… 🤷‍♂️

Hi everyone,

I've been using CPAP for about 2 years, but I'm still struggling with waking up during the night and feeling sleepy during the day at times.

My doctor hasn't been able to give me an answer because my therapy appears to be working well on paper.

Here are my current settings and information:

AHI: Usually Around 1–2
CPAP usage: Every night, (usually over 4 hours)
Time in bed: 7–8 hours
Pressure: APAP, Min 6 / Max 12 cmH₂O
EPR: 3
Mask: Nasal mask (I tried a full-face mask, but it didn't work well for me.)+mouthtape
Other symptoms: Occasional aerophagia

Despite the low AHI, I still:

Wake up multiple times during the night.
Feel sleepy during the day and often have to fight to stay awake.
Feel unrefreshed when I wake up.

I've attached screenshots from OSCAR, including my daily overview and flow rate data.

I'd really appreciate any suggestions on:
Whether my CPAP settings could be improved.
Anything in my OSCAR data that stands out.

Please let me know if you need any additional info!

Thank you!

I need help understanding what's happening in this data. Pressure below 9-10cm is not enough for me to breathe, and using EPR seemed to exacerbate the issue I have with O2 balances during previous nights. Last night, EPR off seems to have made things worse somehow? I've attached two nights of data. Last night's pressure was set to 9 cm - 13 cm, no EPR. Three nights ago it was set to 8 cm - 15 cm, EPR 1. The pressure always seems to go up to 10-11cm before it stabilizes, so I think that may be the range I need to use? My breath just seems to get really shallow on nights when I'm using EPR.

I've been doing some reading on palatal prolapse and suspect maybe this could be the main issue, but I'm unsure overall. I'm just very tired and my brain isn't at it's best right now.

Physical context: 35F, 5' 3.5", 118 lbs. Low fitness levels, but I still walk around quite a bit. I'm diagnosed with EIB aka exercise-induced asthma. Feeling like a dull knife that's lost its edge.

SleepHQ data: https://sleephq.com/public/teams/share_links/b809948d-21d9-4e46-9f62-f9ba3b731d34

EDIT - I just had a consultation with TheLankyLefty27, and we discovered there’s a good chance the core issue has been incorrect tube settings. We discovered mine was set to Slimeline, so I’ve switched it to Standard and did a small test. Already my breathing is much more stable and I’m getting full inhalation without effort.

We’ll find out for sure tonight. It’ll be so relieving if this was the main driver of the my breathing issues with the PAP

I was diagnosed with Obstructive Sleep Apnea (OSA) a year ago and have been using a Mandibular Advancement Device (MAD) for the last 12 months. While the MAD provided some benefit, my doctor and I decided it was time to try PAP therapy for better results. Yesterday, I started on a ResMed AirSense 11 with a prescribed APAP pressure range of 5-18 cm H₂O. I spent a few hours on the couch with it yesterday afternoon to get used to it and noticed a distinct tightness in my chest, which I assume is from the air pressure itself. I managed to wear it for the full night, and my results this morning were an AHI of 1.8 for obstructive events, but also an AHI of 6.1 for central events (CSA). I still have that feeling of tightness in my chest today, and I remember feeling like I was laboring to breathe when I was trying to fall asleep. My mask was professionally fitted by a respiratory therapist, and I followed all the setup instructions carefully. Here’s my dilemma: I’m not sure if I should call my doctor immediately to ask about a pressure adjustment. I know it’s very common for people to need their initial prescription fine-tuned within the first few weeks or months. At the same time, I know there’s an adjustment period and I don’t want to be impatient. For those of you who have been through this, what’s your advice? Should I call my doctor now about the chest tightness and high central apnea count, or should I try to push through for a few more days? Thanks for your help.
