Waking up often - new to BiPAP - neelsk - 10-20-2019
Hi All,
Ive recently been diagnosed and went through a CPAP and then a BiPAP titration. I received my Dreamstation BiPAP Auto 2 days ago and have some questions.
You will see from the chart attached that I wake up every 1.5 to 2.5 hours. I'm not quite sure what woke me, but it felt like i couldn't breathe. I'm also attaching 3 zoomed in portions of the flow rate chart for the times I woke up. Every time there seems to be a significant spike.
Can anyone make sense of this?

Hello neelsk,
I can’t honestly say why you are waking up so often, except that you say that you feel like you can’t breathe. Possibly raise your EPAP setting to 5cm. Also, the Pressure Support range 2-6 could be narrowed, maybe limit the range to 2-4.
I’m no expert on BiLevel settings, so if anyone else can help, please do.
Also, the clusters of Obstructives suggest a positional problem. You may be tucking your chin to your chest. Many folk here have solved that problem by wearing a soft cervical collar.

Maybe try the collar first before making pressure changes.

Your wake times and intervals are also some time after you are likely to have gone through REM sleep (dreaming). It isn’t so uncommon to awaken after having dreamt. Maybe with the novelty of PAP therapy you are more aroused generally and under stress. You are more vigilant.

The spike I believe are recovery breaths, likely after you are awake, not the cause. Each of these awakenings have some flow limitations preceding them, but nothing that should be waking you.

I expected one of the previous posters would have pointed out you have what appears to be positional obstructive apnea. These are serious clusters of obstructive events that cannot be opened regardless of pressure. I really think you need a higher EPAP min setting, but the main problem is you are tucking your chin and obstructing your airway. Please read the links in my signature on "Soft Cervical Collar" and Optimizing Therapy" with focus on the positional apnea section. You will see a number of charts that, like yours, show clusters of persistent obstructive apnea, and how those can be resolved by fixing the chin-tucking.
Your settings are far too generalized. Please set EPAP min to 8.0, PS min to 3.0, PS max 4.0 and IPAP max can remain at 25.

Post #2. I pointed out the positional Obstructives and suggested a collar.

Thank you all for the replies. I will look into the collar and update you in a week or two regarding the results.
Regards,

The fragmented sleep you're experiencing will likely subside as you adapt to the CPAP therapy.
The other suggestions made in this thread are good ones to be followed, but it may also take some patience for the fragmented sleep to subside.
