Higher AHI since concussion, HELP - KCFLY - 10-05-2021 Hello! I've been using BiPAP for almost 2 years after using CPAP for a couple years prior. I was switched to BiPAP when I started getting more and more centrals. Anyway, back on Sept 8th, I was a passenger in a car accident and got a pretty good consussion out of the deal. Since then, my AHI has been much higher. ( I was averaging about 3 before the accident, average of about 7-8 the last couple weeks ) Im going to try and attach last nights data for anyone to give me some suggestions. Seems like after I get a bunch of OSA events and the pressure maxes out, it triggers some CSA events and cycles back and forth. How do I get relief here? I had a great sleep doc who just recently retired and I'm still on the hunt for a new doc. Thanks in advance, RE: Higher AHI since concussion, HELP - Gideon - 10-05-2021 See the clusters of obstructive events? They are an indicator of a form of positional apnea that is typically caused by tucking your chin toward your chest. The first try at fixing is to try a simple pillow modification. Flatter, less firm, a feather pillow vs foam, a buckwheat pillow, or simply using 1 vs 2 pillows. If this doesn't work a soft cervical collar usually does. Read the Collar wiki article linked in my signature. BTW increasing pressure does not resolve this. If you can provide a 10 minute zoomed image of your chart It will help us with the nature of the Centrals that you are having. RE: Higher AHI since concussion, HELP - SarcasticDave94 - 10-05-2021 The Obstructive Apnea tend to appear in clusters as in Positional Apnea. Do you sleep with a high stack of pillows after the accident? Either that, or somehow your chin is pointing towards your chest. Either will kink your airway like a garden hose. The CA are another story. Maybe the PS is causing higher CO2 flushing. Did you raise pressures to combat the Obstructive events? RE: Higher AHI since concussion, HELP - KCFLY - 10-05-2021 Thanks for the quick response. I currently just use one fairly flat foam pillow. I'll see if I can try a feather pillow tonight. Here is a zoom from the chart I posted previously I know pressure won't fix this, part of the problem. Raising pressure would only lead to more centrals, etc. Anyway, thanks again RE: Higher AHI since concussion, HELP - KCFLY - 10-05-2021 (10-05-2021, 07:01 PM)SarcasticDave94 Wrote: The Hypopnea tend to appear in clusters as in Positional Apnea. Do you sleep with a high stack of pillows after the accident? Either that, or somehow your chin is pointing towards your chest. Either will kink your airway like a garden hose. Since it's Hypopnea and not Obstructive Apnea, it's likely only a partial kinking. Just one farily flat pillow. That hasn't changed. These pressure settings are what I have been using since Feb of this year when I saw my sleep doc. RE: Higher AHI since concussion, HELP - SarcasticDave94 - 10-05-2021 OK, is it possible your accident injuries are making you sleep in a different position, one that's increasing likelihood of chin tuck? RE: Higher AHI since concussion, HELP - KCFLY - 10-05-2021 Sleep position changes could be a issue. Most of my physical injuries are pretty much healed up, its the concussion symptoms that remain at this point. I typically change positions through the night. I have looked at the collar wiki, maybe that is the solution. (Not something I would look forward to, LOL) RE: Higher AHI since concussion, HELP - SarcasticDave94 - 10-05-2021 Yep I copy. Adding 10 or so sleep accessories isn't very appealing.
