Just for reference, my jaw goes slack when using a full face mask and my mask ends up in my mouth. To fix this issue, I use what is called a boil and bite mouthguard; used by ball players and MMA athletes. This keeps my jaw from going slack and allows my mask to stay in place which effectively aids against leaks. I am not sure why you are using the appliance but if the reason is your jaw slackens when sleeping, I would try the boil and bite mouthguard. You can buy them in a lot of big grocery stores, drug stores and amazon, etc.
Who are you waiting approval from for the machine purchase? An insurance company? In any case, I would definitely pick a major maker rather than a cheaper no-name off brand machine. I have learned about machines on this forum that I have NEVER heard of and they must sell cheaper and low volume and I would wonder about warranty and support. Did you get a prescription for the bipap and do you have a copy? That really would be a great jumping off point for therapy as you will then be able to drive your own treatment with a little more direction rather than lay it all on a med professional.
Neck size is an indicator that a person may have a propensity for developing OSA but your traps certainly are not involved in the area where OSA occurs. You BMI needs to be kept in check and exercise helps with that a bunch as fat is a much larger contributor to apnea issues. I am no longer an active lifter as I have had some med issues in my old age but anything over 17" neck may contribute but that measurement isn't taken over the traps... The upper chest development and larger lung capacity means treatment will likely require higher pressures but should CAUSE OSA. My current bipap pressure is 25/21 and that is about max any machine can deliver. Smoking and drinking can also contribute but you don't sound like this is a factor in your possible therapy... just keep the BMI reasonable as any weight lifters are not big on diet and can get pretty stout... some aerobics mixed with lifting is always a great idea and also contributes to heart health. good luck.
Physiology changes over time; I suspect that it would be a great idea to have another sleep study to get a good baseline for the new appliance going forward into the future. You can read medicare guidelines online and that would likely be more help than asking folks on a forum OR you could ask a sleep dentist if he would recommend a new study and if he believed medicare would foot the bill and then have the new appliance made from there. Just too much time has passed, in my amateur opinion, for a 9 year old sleep study to be the basis for any new treatment option.
Small polyesther rods in your palate... goodness, who thought up that one?
Being unaware that ResMed ventured into the oral appliance field, I looked at a youtube video and it definitely had bit impressions for teeth on both upper and lower jaw. The gizmo appeared to have a way of ratcheting out to extend your jaw or retract as well I guess. If it is just resting on your lower teeth with no bite impressions, doesn't seem like it was fitted correctly. If your insurance paid for this gizmo, perhaps they could interject themselves into the process with whoever billed them for the fitting.
I found that with certain masks, I had air leaks into my eyes. Although my eyes were shut; it was still most irritating. Could you have a mask that is leaking into your eyes? These leaks are kind of small compared to whole mask leaks. What type mask are you using? You shouldn't be getting dryness in your eyes as a result of therapy unless the mask is a problem to my thinking but I am just another patient.
That link went through without the anti virus software complaining.
I use AVG anti-virus and they blocked the link you gave noting it was infected with a virus. You might want to scan your computer for viruses after looking at the link from ozoneservices.com.
As a camper myself (Have a Keystone Cougar 5ver), I bought a generator for dry camping; not keen about the solar panel life and like my A/C, etc. I have a 3500 running watt Champion generator that I also use at the house when we have one of very frequent power outage. It has a push button start and if positioned away from a bedroom (either RV or home), isn't too annoying. We live rural as you might have guessed. Champion makes a dual fuel (propane / gasoline) generator that I really like and it is ultra dependable. Only thing that could be improved is some sort of gas gauge because filling (re-filling mostly) in the dark makes it easy to slop gas all over. I have never used the generator on propane. I bought a slightly used Generac home transfer switch on craigslist and had an electrician install it. I can power up the kitchen minus electric stove and microwave, the bedroom where we have a window A/C (we cut off main A/C at night to save a couple bucks), living room, bath, office; in fact most of the house other than A/C, well pump (240V), microwave, water heater and electric stove. Anyway, when power goes out, I start the generator, plug into a supplied outside wall outlet and flip the switches on the Generac from LINE to GENERATOR and we have power. Our power can go out for a few days at a time so I keep a few 5 gallon gas cans on hand. Life goes on in the event of a power outage. I can haul the generator with us on camping trips, if needed and it is RV ready; just plug in my 30A RV power cord and I am ready to brave the wild; Bipap works fine btw as does A/C; Just can't do A/C and microwave, etc, at the same time. I put the fridge on propane and the water heater on propane only. It works. And no solar panels with inverters and being without A/C (live in Texas!).
