position of nasal cannula

[kdf330]

my mother was recently put on O2 at home. I was told that the 2 prongs inserted in the nose should curve down, but my sister was told they should curve up.  My mom complains that it "digs" in her nose and is very uncomfortable when it is curving down.  What is the correct thing to do?

My new nasal cannulas are straight, not curved, with a small tab.  Does the tab go at the top or bottom?  I seem to be able to hear the air flow with these. Is that normal?

I've been wearing the nasal cannula for 24/7 for 9 years. I make sure the flow of air goes back.  It will go down to my lungs.  Letting the oxygen hit any part of the inside of your nose just dries the heck out of it and creates other never ending problems.
