Machine settings advice for my report [central events]

[Walla Walla]

The Hypopnea's you had on auto was the main reason the pressure went up before. I'm not an expert but I think you may end up on a different machine.

Here's closeups of some CAs from last night if that helps;

At a pressure of 8 you had zero OA events, that tells me that you could go lower and see if that helps settle out some of the CA events.  If you start seeing more OA events then yes, you'd need more pressure.  Again, starting CPAP is known to cause CA events until you get settled in, unless you were diagnosed with central apnea.  What did your sleep study show?

Thanks, maybe I should give it more time and see if I get used to it. My sleep study was an at home oxygen sensor test, like a watch. The results simply came back to me as "moderate sleep apnea" - I asked for more detail but they didn't give me any. I have a follow up appointment on Friday so I can see if I can find out more.

Please read the link in my signature on organizing Sleepyhead charts. You are using 3-images to show what fits in one nice package. Your pressure rises due to flow limitation, which is not uncommon with CA. You are going to probably end up using an adaptive servo ventilator (ASV). The centrals appear to be properly identified, and we have already thrown everything we have at the problem by keeping low, fixed pressure without EPR. You should start persistently complaining to your doctor that this therapy does not work and you want an ASV titration. He will think you're nuts until he finally gives in. We have many members on ASV and it works great. You get low, auto-adjusting exhale pressure to prevent obstructive apnea, and adaptive pressure support that resolves centrals and hypopnea. It is an amazing technology, but pretty expensive, which is why you have to jump through hoops to get it.

At this point, you can pursue any pressure, EPR or other setting you want, but your best shot at making this work is to use the low fixed pressure without EPR. There are a significant number of people that do resolve the centrals with time, and your doctor is unlikely to make a decision to pull the trigger on a higher end evaluation for at least a month. Still can't hurt to have an honest discussion with him.

Hi airoutlaw,
WELCOME! to the forum.!
Good luck with CPAP therapy.
