Looks like mine after leaving them with the ol lady for a weekend. It really boils down to how long it's been deflated like that.
I would mist her also with an atomizer actually, and keep the fan off for at least half day or better. She's going to lose some leaves, but she should pop back. Try to get some spray under the foliage as well, I think leafs probably absorb water better on their undersides, just don't over spray because of the weight of the water on the plant. I would do it several times over several hours. It's certainly worth a try, I've seen them that bad and make a comeback before, and that plant has a lot of foliage, so it should spring back.
