I am presently trialling a cpap machine and whilst it has reduced my ahi's to 2-3 I still feel terrible when I wake up from sleep at night or during the day. The set pressure is 10.2 and ramp time is 5 mins. I am hesitant to keep using it. I have been on it for over a month. Any suggestions would be greatly appreciated. Geoff
I am no expert, having been on CPAP for 2 months just about. I too have a set pressure.
In my experience, having been sleep deprived with severe SA, it took 2 or 3 weeks before I started to feel "great" .... took time for my body to adapt, also took over a week to get the mask right, and deal with the panic attacks.
My advice is to download the sleepyhead software, and check your results every day..... more than the AHI.
I could see my time in apnea every night was getting less and less, and this in itself re-assured me.
Be brave, tough it out..... it is totally worth it in the long run.
I am still fairly new to CPAP (been using the machine regularly for about two months). I have had only a handful of days where I've felt good in the mornings.
I, too, recommend downloading the SleepyHead software and looking at your data with that if you have the means to do that.
It tells you a lot more than just what your AHI is. For example, in my case, I was having almost no apneas during the early part of my sleep but a whole bunch clustered together in a 2-3 hour period later in the night. My average AHI was around 5.0, but the AHI for that 2-3 hour period was much higher.
SleepyHead will let you see what type of events make up your AHI (apneas, hypopneas, central apneas if any, RERA (respiratory effort-related arousals) and it calculates your total time in apnea.
It took me a while to learn how to generate the graphs and upload them here (I recommend imgur.com for ease of getting your images to display here) but the time spent has been well worth it.
People on this board are great about looking at your data and offering analysis and suggestions, too.
I went to my sleep doctor for my first follow-up visit about a month ago. I was sort of expecting some data analysis from him, but all that he did was to print out a report from my machine's reporting software that gave my average AHI. Unless your doctor is unusual, you're probably going to have to do the work yourself if you want to investigate why you may not be feeling well despite using CPAP nightly.
Your data may show that a fixed pressure is not doing the job for you and that you really need auto (APAP) which varies pressure within set limits to respond to your detected apneas.
I have found that getting even a night or two of sleep with very few apnea events leaves me feeling so much more energized and alert that I barely recognize myself. It's a huge positive reinforcement for using xPAP therapy for for using SleepyHead to find out if my machine settings need adjusting.
