I hope that your girlfriend gets better soon. It is very stressful for you, but know that the medical staff is always doing all that they can to help her recover. What hospital is she at?
My parents were traveling in Quebec a few months ago and my dad had heart failure. He was too critical to air-lift him back to the U.S. so he had emergency surgery at Hopital Laval on Chemin Sainte-Foy. I flew from California to Quebec to be with him at the hospital, and it was very very frightening so I know what you are going through right now.
Thankfully, the medical care my dad received in Quebec was excellent and he completely recovered. I wish the same for your girlfriend.
