Pugsy has offered some excellent advice. I too think that the min EPAP setting is too low. If bumping it up to 6cm seems like too much when you first try it, then first bump it up to 5 for a few days and then bump it to 6. Lowering the max IPAP to 10 for a while is also reasonable in light of the CAs. For the time being keep the PS setting at PS = Max IPAP - min EPAP so that the pressures are free to roam.
You say that sinus pressure is a big issue for you. And you use a full face mask. The FFM is a very reasonable choice under the circumstances. But even so, relieving the sinus pressure as much as possible is an importantpart of making BiPAP therapy both more comfortable and more effective. And you're also uninsured---so we need to keep that in mind too. But we need to know some additional information about your sinus problems.
1) Has a doctor of some sort given you a formal diagnosis of the sinus problems? If so, what was the diagnosis and what was the recommended treatment?
2) Are all of the sinuses involved? Or are one or two much more problematic than the others?
3) Is the sinus pain usually bilateral/symmetric (hurts on both sides of your face in the same location)? Or is it usually unilateral/nonsymmetric (hurts on one side of your face at a time---the side that hurts can switch though)? Where is the sinus pain/pressure worse? In your cheeks? Above the eyes?
4) Are the sinuses blocked because of nasal allergies? If so, what kinds of things are you allergic to? Do you have a well defined allergy season?
5) Has a doctor
recently evaluated your sinuses and ruled out a chronic sinus infection of some sort? Have you had sinus infections diagnosed in the past? Have you ever taken antibiotics in order to eliminate a sinus infection?
6) How do your sinuses react to warm, humid air? In other words, does taking a hot shower help the sinus pain or make it worse?
7) When you bought the BiPAP, did it come with a heated humidifier? Are you using the humidifier? If so, what setting do you have it on?
You write:
I have tried everything including sinus surgery to clear turbinates to keep my sinus clear and my headaches down.
Can you give us a rundown of what "everything" includes? In other words, have you tried any of the following? Did they make any difference at all---even if it was just for a little while? Do you still do any of the following on a regular basis?
1) OTC antihistamine pills like Claritin, Zyrtex, Allegra, Benadryl?
2) OTC decongestant pills like Sudafed?
3) OTC pain medication like ibuprophen or tylenol?
4) OTC decongestant nasal sprays such as Afrin? (NOTE: You should only use something like Afrin for very short periods---after three days of use Afrin and other decongestant nasal sprays will trigger
rebound congestion and you'll be worse off instead of better.)
5) an OTC nasal spray called NasalCrom? (Note: NasalCrom is for allergic rhinitis and is designed to be used on a long term, daily basis; it is NOT a decongestant nasal spray.)
6) OTC saline nasal sprays? (These can be used daily for long periods of time.)
7) OTC saline sinus rinses or neti pots?
8) Prescription allergy
pills? If so, what kind and what dose?
9) Prescription steroid nasal sprays such as Flonase or Nasonex?
10) Prescription antihistamine nasal sprays such as Astelin?
