I was hoping there are some members who are well-read on oxygen saturation levels. I've recently purchased a pulse oximeter for overnight monitoring, so I was hoping to gain some insight about the readings. Some of the questions I was hoping others could answer are:
1) What's considered a low oxygen-saturation level?
2) Are drops of 4% in oxygen dangerous?
3) Does anyone else have oxygen saturation data they would feel comfortable sharing?
Thanks for taking the time to read through my post! Any commentary is welcomed
I have been able to deal with my fatigue, mainly be discontinuing my use of CPAP. About twenty days ago, something dawned on me. I had not tried sleeping without some form of treatment for about three years. That is, for three years I had always either used a CPAP or an MAD. In addition, I started reading a lot about iatrogenics (when treatment causes more harm than benefits), and thinking back to what my sleep specialist asked me during consultation: "how much of this do you think may be in your head?". The importance of that question is to remind you that there is almost always a psychological factor at play in the experience of any given health complication, and OSA is not exempt. So, I started thinking about how I started getting involved with OSA treatment, what led me there and why. It became clear to me in retrospect that there was certainly a lot of anxiety present during the days leading up to me receiving my first mode of treatment. This is all to say that, well, I do have OSA, but perhaps it is more tolerable than I have been telling myself over the past few years, and, importantly, there are other things I have been able to do to help mitigate the severity of my symptoms but also the degree to which OSA manifests itself.
Somethings that have helped me out:
1) One of the first places that your body deposits fat is the base of your tongue, so being even just a few pound overweight can worsen OSA.
2) Avoiding inflammatory foods, particularly closer to bedtime, has proven helpful.
3) Ensuring clear nasal passages to maximize nasal patency. We are supposed to breathe through our noses, except when we need more volume, such as during exercise, so naturally breathing through your mouth typically leads to worse OSA. Pay close attention to your nasal congestion during the next time you eat something say high in sugar or fat or dairy. I think you will find a noticeable difference/response. Identify your allergens and avoid them.
4) Positional therapy. Meaning, OSA is typically less severe when sleeping on your side, and sometimes there is even a better side to sleep on (left vs right), due to the asymmetries in your passages.
5) Exercise in general. Think about OSA for a second, your brain/body doesnt get enough oxygen, so compensatory responses come into play. For example, heart rate increases, respiratory rate increases, mouth opens, etc. Optimizing your resting heart rate and your oxygen-delivery efficiency will benefit you.
6) Buteko breathing method (let me know if you have trouble finding this). Essentially, there are ways to breathe that are ideal for avoiding OSA, and the good thing is they can be trained into you.
7) One happy medium I found was not wearing the CPAP for the first half of the night, and then putting it on for the second half. This helped reduce the feelings of fatigue when using CPAP, making for a decent sleep.
So, where am I at? Well, I'm waiting to see a second ENT to hear their opinion on me receiving a less-invasive surgery, such as trimming some of my soft tissues. Also, there is a model of a MAD that I would like to try out that I've created a post about in this forum. It's call Oventus. In the meantime, I'm continuing to exercise to reduce my weight. I've been sleeping very well, though a few bumpy nights here and there.
Hey Tjack. I'm a 27 year-old who was diagnosed with mild obstructive sleep apnea. A level-three study that included sleeping on my back showed an AHI of 7.8, and a level-one study that included me sleeping on my back showed an RDI of 4.2, but I wore a MAD. I'm healthy, skinny, and physically active.
I tried wearing CPAP for about three years, and I tinkered with settings (i.e. pressures, ramp, humidity, etc), masks (i.e. nasal vs full-face), my diet, my level/types of exercise, and overall sleep hygiene habits. I tried nasal dilators, CBD oil, sleeping pills, nasal steroids, and even lavender oil. I've also spent countless hours reading clinical literature, reading through sleep forums such as these, and even recording my own personal sleep data to analyse. Throughout the entire trial period of three years, I was still experiencing the same exact level of fatigue when wearing the CPAP by the end. I spoke with Ear-Nose-Throat doctors, respirologist sleep specialists, multiple general practitioners, and my family doctor. No one had any answers to the question of why do I feel fatigued (more tired than usual) when I wear the CPAP?
I hope I haven't pushed you to lose hope, but I just want to be open with you and perhaps help you avoid some of what I've gone through.
The first thing I would like to say is that there is data that indicates that it may take some time to "catch up on sleep" after experiencing untreated sleep apnea, and two weeks of CPAP isn't conclusive. Meaning, you may be playing catch up still, which explains your feelings of fatigue.
Second, when I spoke to my sleep specialist regarding the fatigue I feel after a night of wearing CPAP, he said to me that it's probably because the CPAP is doing more disturbing than helping, as I only have mild sleep apnea. I realize that is vague, but essentially he didn't have an answer (nor does anyone else insofar as I have looked), but he said that it is something he sees in patients from time to time.
Third, there is research demonstrating that CPAP for mild-sleep-apnea patients is often ineffective.
Now, with all that said, there are other options available, and there are small changes to lifestyle/sleep hygiene that can also go a long way in improving your quality of sleep/lowering your AHI/RDI. And, as mentioned before, you're too early on in the CPAP trial to come to any conclusions regarding your compatibility with CPAP as a treatment, so give it some more time and try working with your sleep therapist. The pressure just might be too high or you may be acclimating to the disturbances that CPAP engenders or nasal patency may be poor. There are so many angles to work from, and I'm assuming many of those are still unexplored by you. Sleep-apnea treatment is very individualized. There's no one-size-fits-all treatment plan out there, so start tinkering with the variables, and feel free to post here whenever you're dealing with unanswered questions.
Has anyone tried the Oventus O2vent? For those just hearing of it, it is basically a MAD that has an opening at the mouth as a second port for air intake. Or does anyone know where I could read some honest reviews?
I strongly feel that leaks aren't the cause of my dry eyes, though I can certainly see them being responsible for waking me up on occasion. One thing I really dont like about the full-face mask is the wind burn it leaves around the mouth and nose, so I'm going to try with a new nasal mask. Thanks as always for commenting!
Hi Sierra! Yes, there is a sleep doctor involved. At this point in our investigation he has scheduled me for a second level-one sleep study, which I will be doing in about 10 days. In addition, I have been referred to an ENT to discuss the possibility of improving nasal patency or removing soft tissues.
Those were the thoughts of my sleep doctor as well, although he was not the one to assign me the MAD (the MAD was assigned by a dentist with training in sleep medicine).The only other sleep study I have done was a level-three sleep study, which concluded with an AHI of 7.8 (without treatment).
Yes, I know who you are speaking of, and I'm hoping they stop by haha.
I've decided to give the MAD a better/fairer try than I had previously given it. So far I've been wearing it for about 9 days, and I'm finding it more tolerable than I've ever considered it in the past. Using pillows for elevation seem to help as well, but I'm just theorizing. I record myself sleeping, and during small periods throughout the night I have a light snore, but I'm usually quiet, which was also noted on my level-one sleep study above, for what that's worth. I wake up still, one to three times, which is frustrating and annoying, but I would say things are getting better (or as much as one could say they are in the small span of 9 days). Next thing to get is a pulse oximeter so that I can start compiling data while adjusting variables with the MAD!
Last thing I wanted to mention to you, because you weighed in on it earlier, is that my eyes are still very red in the morning, and typically maintain much of the redness as the day goes on. I find this so confusing, because I was sure that it was the CPAP's fault, but now it seems like it cant be the CPAP's fault nor my oxygen-saturation level's fault (because my oxygen saturation was fine on the CPAP)! I've been using high-grade "complete" eye lubricants for 5 days or so, but they're seemingly ineffective. Back to the drawing board I suppose..
Thank you for commenting!
Thank you to the both of you! I just downloaded OSCAR, and I can already say that I'm quite excited about the variance in data it provides.
@Sierra. I'm trying to upload a post of images for my Level-One Sleep Study, which is comprised of 7 photos. When I write the draft and check the preview, everything seems to be fine; however, when I post, it shows up blank, as you can probably see in the post feed. Do you know how to resolve this issue?
Hi to those reading,
I have attached my Level-One Sleep Study Report in hope that members of this community have some insight or comments to share. During this study I wore my MAD along with nasal dilators. Thank you sincerely for taking the time to read through the report, and please dont hesitate to ask any questions should you have any.
I was wondering if anyone has any recommendations regarding pulse oximeters. I would like to record my heart rate and oxygen-saturation levels during sleep. Thanks for taking the time to read!
