Hi, I have a couple of suggestions based on what my dme company did for me. They have a respitory therapist who comes to me or answers questions on the phone.
Here's what she told me:
you need to select the correct size nasal pillow that fits you. Mine came with three: s, m, lg. I use the s one. See if yours has one or more nasal pillows that came in the package with it.
my gal told me never to use vaseline or any kind of patrolium products on my nose, and no creams on my face, as it will cause the silicone to deteriorate and leak. She suggested my using aloe vera gel w/ lidocaine--just like you get for sunburn relief. she said to put a tiny little bit around the edges of the nostrils--DO NOT PUT THIS UP IN YOUR NOSE!! i have found this works very well. it sort of moisturizes that tender tissue around the nostril and just on the edge.
Also, using products like Ayr or other saline solutions help keep nose and sinuses moist.
if you have a humidifier, use it!!!! i have found it very helpful in keeping everthing in my nose, sinuses, and throat nice and moist.
and lastly, be sure to wash everhthing (take your mask apart, humidifier, hose, etc. whatever you have) and rinse it well, and often!! my gal told me that i can use any kind of gentle soap--i use a non-antibacterial, gentle dish washing liquid, only a tiny bit. Be sure to air-dry everything and keep it out of the sun.
I sure do hope these ideas help you! God bless you.
