RE: HELP DIZZY AND FATIGUE SINCE CPAP
I had a look at your sleep study and I am surprised that they did not discuss oxygen infusion into the airline with you with the number and extent of desat's that you are showing. Again, remember that anything under 90% SpO2 is considered respiratory distress and, for instance, paramedics will give you oxygen as soon as they see this until it can be further analyzed.
The sleep study is generally set up to try and differentiate between centrals and OSA event. However, if you have a blower that does NOT have data features, you will not be able to follow along on a long term basis.
I would think that you want to investigate your SpO2 (blood oxygen level) through the night, recording same and laying it against the data which you don't have.... but at least you will see the ongoing picture of your SpO2 and if you have drops below 90% through the night you want to head straight back to your sleep doc and ask some questions. BIG questions.
What will happen without infused O2 to keep your SpO2 above 90% is that (I suspect) as you approach REM sleep and your breathing becomes shallow, your SpO2 is dipping (diving?) and your body is being aroused by your autonomic nervous system. Bingo. No REM sleep. Or... little REM sleep. Do you happen to recall vivid dreams when you awaken? And do you awaken with a start? Or in the middle of a good dream? Do you ever awaken in a sweat or gasping? Your sleep study shows all too many desats for my own personal comfort and I know that in my personal situation, supplementary oxygen infused into the air line from the blower at a rate of about 4L/m increased the oxygen in the air from 21% to about 30-32% and it made all the difference in the world to me. I started sleeping through the night much better asides from the pit stops, etc.
The other thing that you need to know is that OSA/sleep apnea is closely associated with a host of other ailments, not the least of which is Atrial Fibrillation; and, AFIB is not at all pleasant and will give you some of the symptoms that you are complaining of. It is not all that easy to detect and you want to detect it in the early stages so that you can get the issue addressed and not have to mess around with it for five years like I have had to do. You have a couple of the top electrophysiologists (cardiologists all) in the world near at hand should you be diagnosed with AFIB.
But, I think the first question I would ask is why my (your) SpO2 has been permitted to drop so low and so often through the night without being addressed. It is easy to address. I bought an Everflo Q 5 litre/m oxygen concentrator and an inline nipple to infuse it. Problem solved.
The Contec CMS50EW should cost you no more that $125, is rechargeable and records up to 24 hours. Its accuracy is superb. If you get one use some green or blue masking tape, judiciously placed, to keep the unit affixed to your finer and steady. Best part is that if your computer has Bluetooth you can transmit the data wirelessly.. else they provide a data cable. Easy enough to use. And you will get an ongoing picture of your SpO2 situation at night and your pulse rate. And be assured, if your SpO2 is plummeting and your pulse rate is rising, your blood pressure is skyrocketing and placing you in danger of a stroke. And if you have AFIB, you want to know about it immediately so that it can be treated. The first thing they should be doing is putting you on Warfarin blood thinner to reduce the stroke risk. Don't take these other and newer blood thinners as they have no antidote in case of an accident and bleeding.... simple massive doses of Vitamin K reverse the thinning effect of Warfarin but do nothing for these others and trust me, you want an antidote at hand should you get cut or injured internally with bleeding involved. Ask me how I know. Trust me, I know. In real life.
The few extra dollars for a Contec CMS50EW is well worth the investment. I have three CMS50E series pulse oximeters (I believe in spares). The last was the CMS50EW which came right from China, purchased online for about $125 delivered. Worth every penny and they are all well built and reasonably rugged.
We happen to have a BP meter, same as the hospitals use (I am very serious about my health) and untreated sleep apnea is associated with several other afflictions including AFIB, Diabetes, hypertension, etc. They are all inter-related and I consider, in my case, that OSA was the seed that was planted and from which all of the others blossomed. I am fortunate in that I am managing to beat down ALL of these afflictions. They are making a slow but steady retreat and I expect that they will all have been beaten down in about a year from now. There is plenty of good information online... your job is to find it, read it, digest it and make use of it along with your medical helpers. BUT, as I always say... you must be and have a front line advocate. Be your own advocate. Have an advocate should you find you cannot advocate for yourself as I did in 2009. It is important.
Educate, Advocate, Contemplate.
Herein lies personal opinion, no professional advice, which ALL are well advised to seek.
