Is there someone who could come in occasionally and talk to her in Polish if she's still familiar with it?
Now there's a Polish community in UK, there are UK residents of Polish extraction familiar with the language who act as translators for newcomers, but I don't know about "over there".

If lack of oxygen is the issue, can you have a cylinder at home which she can augment her breathing with?

My mother had teddy bears to hug after her Lhasa Apso had to come and live with us - it was the warm contact she wanted, I'm sure.

Good luck, and like everyone else said, take care of yourselves as well.
