my aunt in Israel had an open heart surgery, 4 days after operation she can lay down, can't breath, only can seat up or walk, she did not sleep for 4 nights, what can be wrong ?

I had a triple bypass in Jan 2008. I went through the same thing. Believe it does get better. It was a while before I could lay down. I slept (what little I did sleep) sitting on couch. Did alot of walking all night. But now I am doing fine. So tell her to hang in there it does get better
