Susan -
I can relate to your story. We all did the same thing with my Mom when she died of breast cancer six years ago. However, she was not hopeful - she knew she was dying but it was NEVER spoken about and no, we did not get important things said, but there again, I know I will see her again and we will have all eternity to say things to one another. But I know what you are saying - it was very difficult to have this elephant in the room and not acknowledge it.
As for sleep apnea and surgery, I read (past tense) up a lot on surgeries of the nose and throat for sleep apnea. I do think it works a lot of the time. I have a septal deviation and allergies, plus a receding jaw. I also gained about 15 pounds post surgery and a lot of it is fatty tissue in my throat.
I, however, am unsure if it is my mildly stenosed repaired mitral valve that has caused the mild sleep apnea or all these other factors combined (including being in perimenopause).
Sleep apnea is more common than you know as a person ages, gains weight and as a woman loses estrogen. When I suspected I had SA, the cardio nurse said oh no, you don't fit the profile - it is mostly big burly men with thick necks who have SA. I have come to find out that the biggest percentage of those with sleep apnea are overweight men, but there are a lot with SA who do not fit that profile at all.
I believe my Dad had sleep apnea. He had a small jaw and a lot of fat under his chin and a belly. He did not have valve disease. He died of a heart attack at age 63.
You cannot make your dad, Joanne, wear a CPAP. All you can do is present the facts and see if he will try the nasal pillows. If he won't wear a CPAP, I highly doubt he would have invasive surgery.

I should have surgery on my nose - a great chance to have my nose bobbed for free - hee - but I just hate the thought of doing it - I'm being lazy. It's much easier to put the CPAP on every night. I also am trying to lose weight and trying not to eat right before bed, those types of things. If the sleep apnea is from my stenosed valve, then none of these things will work for the SA anyway.
P.S. There is a guy at work who has been told he has sleep apnea and needs to wear oxygen at night also - he desaturated way down into the 70s at night - we live at 7500 feet here in the Colorado mountains. He will not do it - he is trying to lose weight right now - he is a compulsive eater (his admittance) but he is exercising and has lost at least 15 pounds so far - he's a big guy - anyway he will NOT wear a CPAP or the oxygen. I have tried to explain to him the dangers of not doing this. He chooses not to wear a CPAP, so be it. His life.
Oh the joys of getting older!

Again, good luck with your father, Joanne. Hope he will try the nasal pillows.
