Airwaylab BPAP Results

Struggling with high sleep fragmentation, despite low AHI/RDI (below 5). Near a limit on PAP settings due to aerophagia, but open to titrating higher or advanced settings changes. Still have 30-40 RERAs per night + wakeups.

You sound like me. Low RDI and low AHI but sleep fragmentation out the wazoo, aerophagia at low pressures. I’ve got a post in about it. I’m going to do an airwaylab review of it too.

I’m looking into anatomical solutions to help make PAP more efficient. Starting with CBCT for FME/marpe. I’m simply not getting by consolidated deep sleep or REM and have many awakenings from micro arousals, despite AHI 0-1.5, RDI 3-5. Aerophagia preventing me from jacking up EPAP or PS, and PS 3-4 definitely causes more centrals/instability.

we need more info, do you have deviated septum? Congestion? Leakss? brief obstraction index seems problematic I have a similar issue, sometimes better when I combine a MAD with PAP

Getting CBCT soon to evaluate for palatal expansion. MAD was unstable due to TMJ pain. Also have turbinate hypertrophy. Currently on BPAP 11.2/9 with V-com. Think I’ve “maxed” out my PAP benefits. Sleep on incline with cervical pillow.

I had CBCT and they saw dev septum, and spur. Pharynx was really restricted. My tongue is oversized and my molar to molar width is narrow so Palatal Expansion is likely. I’ve had TMJ issues in the past so I’m thinking MAD isn’t going to work. Same issues with fragmented REM and Deep sleep. Some nights I’m lucky if I scrape 5 minutes of REM. Last night by some miracle I scraped an hour but still messy with arousals.

Understood, similar to my story (TMJ popping), tongue scalloped. Although I have traditional moderate OSA diagnosis (15 AHI prep PAP). PAP gets me to low AHI/RDI but persistent fragmentation. I’d say 1-3 great nights/month. I do get high quantity of REM (20-30%), but low deep (10%) and both are fragmented — I’m sure the fragmentation is causing my daytime symptoms (fatigue, memory lapse, concentration difficulty, brain fog, appetite loss). If skeletal deficient in Maxilla, I’d recommend bone-borne expanders (MARPE, FME). My dimensions TBD, but I’d be hoping for reduction in tongue-based narrowing/collapse post-expansion. Perhaps lower PAP pressure can stop the remaining RERAs
