Do your research and make sure the machine meets your requirements. AirSense 10 is a line of CPAP models AirCurve 10 is a line of BiLevel models Which you should use depends on the details of your Apnea. I prefer the Auto machines for their versatility. You can get your choice of machine, you may need to "shop" different DMEs or you can go Self-Pay. The machine will need to match what your prescription is. Auto vs non-auto is the same billing code so that should not be a problem except for the fact the DME make more money from the cheaper, simpler machines.

Masks, look at the ResMed P10 Pillow mask, it has a simple strap and Sierra has modified the strap so that is definitely a possibility.

You want a full copy, including the charts and tables. All too often I see very important details (central apneas noted in the body but totally missing in the summary.

You should be able to pick a brand (ResMed or Phillips) and a model (CPAP or APAP same billing code) or a BiLevel which allows the prescription written. You may need to let them know what you want and insist on it, BUT as stated above, you will know more after the titration study.

We recently discovered that the 2GB data fills (then overwrites) between 9 months and a year depending on amount of data. we don't know how many hours of use. So we now recommend the larger sizes though even a 2GB will work.

You said "irritate the inside of my nose". P10 pillows should be on, not in the nose. This is usually fixed with the next size up pillows.

Humidifiers are a common source of leaks, Also cats and dogs and CPAP hoses are not always compatible ;-)

Mouth Breathing is when you open your mouth and the air pressure from your PAP is venting out your mouth typically showing on your charts as a large leak which can substantially negate the effectiveness of your therapy. It is generally not good. The solution varies depending on the person

With OSCAR look at your Leak Rate graph where it is shaded (large leak/ LL), flat tops on this graph suggest mouth breathing. In OSCAR right click on the left header of the Leak Rate graph and click on Dotted Lines then select "Leak Rate Upper Threshold" to get a line across the graph for ResMed. Manually set the value for Philips Respironics. Severity depends on how much over this threshold and for how long it is in the Large Leak territory.

How to manage Mouth Breathing, not in any particular order.

Tongue Trick. Place the tongue on the roof of the mouth, Practice during the daytime. The idea is to train the tongue that this is a good place to be, not overnight, but it works for some.

Cervical Collar. A "soft" Cervical Collar (Releaf is popular). This helps support and align the neck and keeps the jaw/mouth from dropping. This is becoming a very popular option. Rarely used prior to mid 2016. Users are posting a high success rate with this device. When OA tends to occur in clusters at different times of night. It's an indication that an obstruction may have occurred when the chin tucks towards the chest. It's common, and the solution is either an ergonomic pillow or soft cervical collar that prevents the neck and head from being out of alignment and cutting off the airway, but they can be comfortable, prevent leaks and prevent an airway from closing up due to tucking your chin to chest and other issues. An Anti-Snoring collar, which has a small strap in back (Dr. Dakota is popular)

It's a very small investment that has worked very well for some people. More pressure may solve the obstruction, or it might go away with positional therapy.

Chin Strap. A chin strap is to manage mouth leaks from a variety of causes. Most result from the jaw-dropping or opening either partially or wider. The chin strap is to gently keep the jaw closed. If you have to crank it shut to make it work this is not the correct solution. Note that your jaw is strong enough to open if it wants to. There is one chinstrap that is notably different than others, the Ultimate Chinstrap, Search for it if you desire.

Ergonomic Pillow or CPAP Pillow, The purpose is to maintain a proper head and neck alignment while allowing for the mask maintaining the seal in multiple positions.

Mouth Guard The concept here is a closed mouth guard to keep the air from leaking out.

Taping. Definitely the most controversial. The purpose of taping is to seal the lips and prevent mouth leaks/mouth breathing. It is not to stop the mouth from opening. I make sure that I can easily open my mouth when taped, if I need to.

FFM – Full Face Mask or Hybrid Mask. This is a very traditional solution and it is generally effective.

Dry mouth is a symptom mouth breathing that is uncomfortable. It can and does occur with some users of a Full Face Mask.

Many users use a product called Biotene to get relief from this symptom.

It isn't as much the low as the duration. Medicare says 8 minutes under 88% qualifies for overnight supplemental oxygen. your stat (<90% 34.1 minutes <85% 0.2 minutes) IMHO of <85% no problem, but the 34 minutes, yeah, I would want to do something about that. CPAP use does improve O2 Sats but I would add a recording oximeter (aftermarket) to validate this or I'd accept the results of a titration sleep study. Either solution would work. What Machine, IMHO the ResMed AirSense 10 AutoSet for Her (The plain AutoSet would also be ok).

Which BiPAP are you on, brand makes a difference, and what are your current settings? not just pressure! There are typically timing and aggressiveness settings that go beyond BPM. Why does he have a timed backup rate? What underlying medical condition does he have?

Flex on PR machines makes many feel rushed as it dictates that you must start inhaling or exhaling now. ResMed tends to follow you.

I would cut and add a velcro strip for added length and adjustability.
