If she had health insurance, which is usual for anyone sensible travelling abroad, even within the EU, that would have paid.
I don't think all emergency treatment is necessarily free in most EU countries anyway. Last year we were in France when a fellow guest was taken ill - he then had a heart attack just before the ambulance crew took him away, and was sedated in the ICU when Dh and I visited next day.
The very first thing they asked us was whether he had insurance, and where was the paperwork. Luckily he'd had the presence of mind to have it to hand before the ambulance arrived.
