December 2025: It's been 9 months since I had ESP (Expansion Sphincter Pharyngoplasty) done, and not only have I not experienced the slightest improvement, but I now cannot even fall asleep without ASV. November 2024: A couple of months ago, I caught Covid for the first time, and since then, the ef...

I cannot even fall asleep at all without ASV is very concerning This sounds like a strong fear of falling asleep without the machine. You might want to experiment with some relaxation techniques or even ask your doctor for a mild sedative for temporary use. Your ASV is not designed to help you fall...

Then why attempt to sleep without it? Because that was the point of having ESP done in the first place, to be able to achieve restful, high-quality sleep without the need for a machine, which is extremely inconvenient in many ways. I also ended up going for ESP out of desperation, as not even ASV w...

I've never heard of post arousal awake pauses and a quick google search didn't reveal much. Would you mind elaborating please? Where can I read more about it? try Google with the search terms "post arousal central apnea". Thank you. If I understand correctly, the difference between central apnea an...

All those central flags you see.......they aren't the cause of the poor sleep...they are a symptom of your poor sleep. Those are NOT real asleep central apneas....they are post arousal awake pauses in breathing that earned a false positive central flag. They are NOT treatment emergent central apnea...

Why are you skeptical? It's a rather common side-effect of CPAP. https://journal.chestnet.org/article/S0012-3692(21)00108-2/abstract Treatment-Emergent Central Sleep Apnea TECSA is a “dynamic” process, with spontaneous resolution with ongoing positive airway pressure therapy in most patients, persi...

If you still have your AutoSet machine, use it for one night. Get a free account at SleepHQ.com, upload your data, and then post the link in this thread. I'm skeptical that you have treatment-emergent central apnea. I was renting the machine but I can share the old data if that helps. Why are you s...

I'll try to keep this as concise and fact-based as possible, so feel free to ask clarifying questions if needed. It's been 9 months since I had ESP (Expansion Sphincter Pharyngoplasty) done, and not only have I not experienced the slightest improvement, but I now cannot even fall asleep without ASV....

Hi everyone, Long story short, I've been on ASV therapy for over 8 months. A couple of months ago, I caught Covid for the first time, and since then, the efficacy of ASV therapy has sharply declined to the point where I’ve spent many nights unable to fall asleep at all. This had never happened befor...

It sounds to me like it could very well be aerophagia, possibly related to your ASV machine having increased the pressures (both IPAP and EPAP) in response to a series of "events", possibly false events scored while you were trying to drift back to sleep. Rather than change the machine's Min EPAP s...

I've been dealing with aerophagia pretty much since the start of my ASV therapy over 8 months ago. By aerophagia I mean excessive flatus due to air swallowing. Honestly, I didn’t mind it at all as it didn’t seem to impair the effectiveness of my ASV therapy. It was just a minor inconvenience. Howeve...

I don't myself see a resemblance between your flow-rate traces and the traces in the articles you link to (or in additional images on line). Instead, I see periods of fairly slow and/or shallow breathing, not the shut-offs typical of palatal prolapse. I don't know how to optimize settings on an ASV...

would you agree that a lack of flow limitation during the events + the long continuous flatten curve suggests a Central Apnea event? No. It would be a guess on my part and I don't do guesses very often but this is one of those times. Unless you know for sure that you ONLY had central sleep apnea an...

ASV model machines do NOT use FOT to figure out if the apnea the machine senses is obstructive or central in nature. So that's why it uses the "unclassified apnea" flag name. OSCAR doesn't do the naming of anything....the machine does the naming and OSCAR just reports what the machine is reporting....

For a long time, I've suspected that my soft palate is the main cause of my sleep apnea. After contracting Covid for the first time and experiencing a worsening of symptoms to the point where I couldn't even fall asleep a couple of months ago, my suspicions have grown stronger. Recently, I read abou...
