The general prognosis for such a person is death
-----------------------------------------------------------------------
Unfortunately, you are right. I have been doing some research on the
net. And she is exhibiting class C symptoms, such as fatigue and edema.
They also perscribing diuretics and ace inhibitors. She is also ging in
for treatment twice a week.  She should quit smoking and stop her
nightly drinking. But from what I read, the prognosis is very poor. The
postive side, she always acts like she is ok and in good spirits.

How she got to this point is obvious. She smoked all of her life, and
to this point she still hasn`t quit. After she was put on oxygen,we
always advised them to move from Denver to a lower altitude, but she
and her husband wouldn`t.  So her condition got progressively worse
until she was maxed out the oxygen levels. The main thing now is to
keep her happy.

But from what I have learned out of all this--just don`t smoke!

doc,
excellent post---far superior to my post.
You showed compassion---I failed to do so.
Keep up the great work.
