  • Don't trust your AHI, understand your sleep study report and take back control of your own health condition.
    Sleep studies (also known as polysomnography studies), are very sophisticated and give a huge amount of data from each night. People are often only given a single AHI number as an overall marker of their disease severity. Personally I do NOT believe that a disease as complicated as sleep apnoea and UARS (upper airway resistance syndrome), can be defined by a single number. In this video I am going to help you understand sleep study reports so you understand what is actually going on with your own condition. You will learn about AHI, and what makes it a poor choice for understanding sleep apnoea by itself.
    I fully appreciate that the TH-cam algorithm will hate this video because it is so long and technical, but I really think it will help some people out there. I think it will help people who are:
    1. Trying to look for an alternative to CPAP
    2. Understanding why they have been told they are normal when they still feel like they have a problem
    3. diagnosis of OSA and UARS
    4. just for general education of their health condition
    I hope you found it useful, Thank you for watching!

    The discussion at 7:20, about AHI relative to sleep position, is so overlooked at yet so critical. It is great evidence for multiple night studies. Having data from a single night is like monitoring someones driving for one day and deciding they never speed because they happened to not drive anywhere that day.

    My first sleep study oxygen reading was 77%. Alarming! But I only had 9 events per hour. That was about 3 years ago. I was first given CPAP, then about 18 months later, BIPAP. Last year, I stopped using my machine for months. After that, a new sleep study by a new doctor: 15 events per hour, 95% oxygen. He put me back on CPAP. I honestly don’t notice a difference sleeping with the machine or without it. I am 68 years old and 20 pounds overweight, working on weight reduction. Last year, I lost 30+ pounds. Thank you for these great videos. Best wishes from Michigan, USA. Side note: I was sleeping in great pain for a couple of years due to osteoarthritis in both hips. I never got a good night’s sleep. I had my hips replaced last year and that has made a tremendous amount of difference in the quality of my sleep.

    During my two sleep apnea studies I couldn't lie in bed as I normally would. I slept almost entirely on my back because I was tied down with massive numbers of data cables. I felt like Gulliver on the beach. Normally I sleep more on my sides because I find it easier to breath that way. The AHI of 80+ was certainly skewed because I was tied down onto my back.

    I now understand my sleep study better thank you - I was going to give up on the cpap it’s been a frustrating journey however now appreciating how serious my Q2 dropping to 60% during my rem sleep I’m going to persevere in finding a mask I can wear all night

    • @VikVeerENTSurgeon
      @VikVeerENTSurgeon  7 หลายเดือนก่อน +2

      You have no idea how happy this comment made me. Thank you!
      Incidentally REM OSA is often related to the tongue falling back. Try wearing a woodyknows backpack (see video on positional sleep apnoea), with a chin strap (see the Knightsbridge dual strap video on it), and a Philips dreamwear nasal cushions (it'll normally fit on any CPAP machine). Use all that and see if your O2 still drops after 3 weeks (takes time for you to get comfortable and to notice the benefit).
      REM OSA also causes a lot of brain fog and that takes time to clear too.
      With time you should be able to stop using the backpack and the chin strap (6 weeks or so?).
      If you are still struggling consider a MAD with all of that and then see if you still have drops occurring. If not wait the 3 weeks for you to pay back your sleep debt and start removing things until you are just on the mask.
      Sorry I can't explain it all to you, but ask your sleep lab and they will explain why it'll work and what order to stop using everything. They will be able to see from the sleep data to guide you.
      Good luck.

      @@VikVeerENTSurgeon you are a gift to all of us - thank you for your detailed response and recommendations- I have not been very happy with my sleep lab the after care has not been great so I saw a different sleep technician who was recommended to me by a friend - she explained my sleep report in detail - also adjusted the pressure level on my cpap machine from 4-6 to 5-9, changed the humidity level and provided me with a different hose that provides warm air and a Resmed nasal cushion mask. I told her I was a mouth breather she explained we often breathe through the mouth because we’re snoring - i trialled the nasal cushion last night without the chin strap I lasted 6 hours and I had 1.4 events per hour, which I think is pretty good as my AHI in the sleep study was 24 I typically sleep on my left side but appreciate I change positions throughout the night- i so wish I could have a consultation with you here in Sydney Australia :)

    100%... I no longer use the resmed app or engage a sleep tech. I use sleep HQ to review my sleep data from my Airsense 10. I used an o2 ring to check my oxygen which was normal during sleep. I ended up needing a travel pillow because my jaw falls backwards when I sleep and now with APAP and the pillow my AHI is on average less than 1 and that's on my back. The reason I mention this is because my sleep study report had a lot of glaring omissions like 0 supine sleep data which I really needed in order to properly figure out the right treatment for me so it's definitely worth educating yourself and take ownership of your own therapy.

I'm pretty worried! His mean SPO2 = 92%, CT 90 =14% (don't know what that is?).

    Hi Dr. Veer - I'm wondering if you have an opinion about the various Home Sleep Test devices currently available. It seems like there is a trend toward smaller / disposable devices (like WatchPat and NightOwl) which rely more on complex tech / algorithms to "estimate" apnea events and sleep architecture. Do you think the Nox T3 (now T3s) is a better device to collect the kind of data necessary to diagnose UARS, for example?

    I have extreme sleep apnea but before i got tested i had recorded my snoring, The recordings show clearly the apneas where I do not breath for a bit then load snoring when I do, but when it gives an overall rating for the snoring it says it is not very loud, and that is because it basically averages the whole night, and if I spend 50% of the night not breathing(yes it was that severe) then that 50 of the night I am not making any noise.

In the supine position, I have an AHI of 7.0 for 83.1 percent of the time. I think I sleep on my side more because I was conscious of the sleep study gear that I was wearing making me sleep on my back more. My question what device would help in this situation? Would an oral appliance such as Mandibular advancement device or a tongue holding device help? I cant seem to tolerate a CPAP machine. Thank you

    wondering about this: I have a heart rate / 02 monitor on my watch. It sometimes shows a steep drop - sometimes down to 70 but then right back up to normal a couple minutes later. Would this be more of a central rather than obstructive? Also separate of that - I sometimes wake up because while I can breathe in through my nose, I can not breathe out through nose and have to exhale through mouth. This is only occasional but worrisome.

    Great video! My sleep studies have no RIP Phase or Flow Limitations data :(. My severe sleep apnea seemed 'fixed' after some surgeries because the AHI was around 5. But the RDI was around 15 and oxygen levels dropped to less than 88% for about 32 mins. I still feel very tired and this has a toll on my mental health but some doctors just dismiss it seeing the AHI alone. Would you say that the RDI and oxygen levels I mentioned explain what I feel? If only my sleep study had RIP Phase and Flow limitation data!

    I can't tell you how valuable this video was for me - thank you so much! I've been suffering from feeling like I haven't slept for years. After watching your video, I asked for my sleep study after they only gave me a single number AHI of 13.6. They then sent some summary information but did not include the graphs. I have interpreted the information based on the guidance you gave. Could you please tell me if I'm on the right track. The data they provided was TST=4h 42min, AHI=13.6, 2 obstructive apneas, 3 central apneas, 8 mixed apneas, 8 RERA events, 51 hypopneas, minimum O2 88%, less than 90% for 28min, mean O2 95.9%, 30% TST in supine position AHI=29.1, 70% TST non-supine AHI=7, RDI=15.3. I believe it indicates that I should stop sleeping on my back, and that should substantially help my sleep apnea. The study also indicated mild to moderate snoring but I don't have the graphs to correlate with sleeping position - I will be asking for the graphs. Am I on the right track? A slumber bumper will probably help me correct? What should I make of the 8 RERA and 15.3 RDI? Not sure what they mean. I've also started your exercises. Thanks again for this amazing video!

      Really hard for me to give you advice based on this, but my guess is that you have OSA when sleeping on your back, and then UARS (see video on this), when sleeping on your side. I would say that sleeping on your side (slumberbump is a good product - but i'm yet to review it), is a good idea. Also think about a Mandibular Advancement Device (trying to do that video too). Sorry I can't be any less vague. I hope it helps anyway.

    Thank you so much for this video! I was diagnosed with mild REM related OSA and mild positional apnea. Oxygen dropped to 85% at one point, and pulse rose to 120 bpm but in both of those instances the report says “excluded periods” for respiratory periods. So I don’t know what to make of them. Total AHI is 5 and total RDI is 28. It was a home study so I don’t have some of the other useful data. Could this point to UARS if I’m experiencing gasping events regularly on my back and yet numbers seem too low for OSA? Would a mandibular device be a good start? They want me on a cpap but I am unsure.

I have observed from my sleep oximeter without wearing CPAP that my oxygen dropped to 84% and stayed at that low level for 45 minutes out of about 3 hours. I also have the normal sleep apnea where the oxygen comes back quickly after a short moments of not breathing. Even with wearing CPAP I observed on the sleep oximeter that I can have and stay at low level oxygen about 90-91% for close to an hour. I asked my sleep dr and the heart dr ( I got PAH from sleep apnea) they both didn’t explain to me as why I sleep and stay at low oxygen level. Do you think this could be a combination or obstructive sleep apnea and central sleep apnea? Thank you 🙏

Thankfully my lungs were fine and then they started the sleep apnea treatment. Go see a pulmonologist. If your lungs are fine then your cpap treatment is probably not effective.

      @@VikVeerENTSurgeon Also, a general question for you if u don't mind. Do sleep doctors account for the fact that patient's don't sleep well or like they normally do at home for in-lab studies? Like the first night effect, i feel sleep inlabs is not as "bad" as it would be for patients at home due to sort of being more alert in a new environment.
      The reason i am asking is because I know for my in-lab, i feel my sleep was not representative of my sleep at home at all. I had such a hard time falling asleep, possibly due to new environment/setting/wires/ being nervous/anxious or something. And then i also woke up in the middle and again had trouble sleeping. This is never the case for me. I'm usually out cold around 11-12 and up at 7-8 AM. And sleep the whole way thru. I actually feel like i barely slept for my inlab study. I recall being awake/alert for a large part of the study, which became increasingly frustrating mentally as i knew this was very important for me diagnostically.
      I feel my in lab study resulted in data that was falsely lower than it would have been had i slept like I normally do. I also had less reduced REM sleep (most of my events were in REM sleep), also making me think had I had more REM sleep my AHI would have been higher. I had an AHI of 6.5 but my sleep doc says i'm fine and don't need tx, despite complaints of classical symptoms such as morning headaches, brain fog/cognitive issues, poor unrefreshing sleep.
      I also saw your video on UARS. I'm just a person trying to get proper good quality sleep. And not have horrible morning headaches. I'm assuming due to my results, they feel i'm on the lower side and don't really need a cpap machine. I feel it doesn't hurt to try, perhaps it would resolve my symptoms. Maybe there are better ways to navigate this, but as a patient and layman, it's hard to know what to do. Any thoughts would be appreciated. thanks again.

    Everyone who sleeps on their back during a sleep study will have apnea. The test is designed for supine sleeping, isn't it? And the study can tell how long you are sleeping and in what position?
    I didn't know anyone is actually allowed to sit up. I was almost strapped to the bed in such a way as to not be able to move from a supine position. My report said to sleep on my back less. I don't sleep on my back nor did I sleep as long as they said. I literally slept about 2 hours if that long. It was 3 or 3:30 am when I finally slept and they woke me up about 4:30 or 5. Never got to see the report, didn't talk to the doctor before or after. Someone even marked out the doctor's remarks about me having minimal snoring. And what gets me is there is always a magic rabbit pulled out of the hat when someone does not have apnea bad enough to use Cpap. Oh, yeah, a number somewhere on that report can be used to justify it. AHI, ODI, etc. "Oh, your oxygen dipped for ten minutes during 7 hours of sleep. You need a CPAP stat."
    Do y'all have no conscience? Being a sleep doctor must be very lucrative. How many doctors do you compete with? How many hours does someone have to actually sleep for the study to be correctly interpreted? How about that? I was told the amount of time I slept was enough. Two hours of fitful sleeping is enough to diagnose someone? When they are waking up because they don't want to sleep? Because they don't want to sleep in a strange place with electrodes taped to them and lights on?
