Well I had another sleep study confirming I have sleep apnea, 3rd time
My oxygen levels averaged 89 and were as low as 86. Does anybody know if that is low?
The study took place on a constant pressure and the report says maximum results were achieved at 7. Of course someone was adjusting the controls all night
I use an Auto machine at home with a range of 6-15.
The problem is I only average about 4.7 hours a night with the machine and general after two hours or so I wake agitated with an elevated pulse and blood pressure.
I calm myself down and give it another go.
I'm not getting quality rest though I do sleep better with the Cpap then without.
I wake agitated with elevated blood and pulse levels most of the time.
I just don't understand why it's not working. I've been using the machine for almost three years now and just not getting the results I think I should. In fact it feels somewhat determental to my health.
Does anybody have any idea what could be causing this situation. My doctor doesn't seem to get it and keeps offering the standard good sleeping habit advice. I've stopped my normal one drink an evening and I'm trying to go to bed earlier and earlier but I don't seem to be making progress.
Some nights are better than others, but mostly it's a disappointing result?
Any theories or suggestions welcomed.
Welcome, Harry. I am sorry that you aren't feeling better after 3 years of therapy. I am a bit confused by your Autoset's settings of 6 to 15. Did your sleep doctor suggest a change after seeing that your maximum results were obtained with only a pressure of 7.0 in the sleep lab?
Obviously, the sleep lab results may not equate with what you do at home in your own bed. I see that you are using Rescan. What is your AHI? If it is under 5, I am not sure why you are feeling so bad, except that you may not be getting enough quality hours of sleep. Your average oxygen level of 89, presumably during sleep, is a bit low, but probably not low enough to supplement with oxygen unless you have other health issues with your heart or lungs. I see that you are using nasal pillows. Are you possibly awakening when you begin to mouth breath as perhaps the pressure ramps up during REM sleep? Look at Rescan to see what's happening at the moment you are awakening. If the pressure suddenly goes up and you are recording a large leak at that time, it would suggest mouth breathing. If you aren't sure, try using a chin strap, or possibly a full face mask to see if that helps.
Blood oxygen needs to be at least 95%. So, yeah, 86-89% is low. Not OMG low but close.
So after you initially wake up, you are able to go back to sleep or are you then up for the rest of the night?
Since you have an Autoset, it'd be interesting to see what the data says. To see what you are doing that wakes you up.
Did you wake up like that in the sleep study?
Ask the doc what they got the AHI down to with the pressure of 7. Did they get it less than 5? Did you have central events if they went higher? With that setting, what did your blood oxygen get to? Was it still in the 80s even with the pressure of 7?
