You need a flashlight or head lamp. Grasp her tongue and pull it out the side of her  mouth. That will keep her mouth open. You'll need to do it on both sides.

If she's drinking normally this isn't  an emergency that would necessitate hauling her if she can be seen within a few days. Feed her cubes soupy.

I don't know how you are flushing but a hose works best. You're going to get wet!
