It someone is feeling faint it is standard practice to lower their head to increase blood flow to the brain. Presumably her husband knew this. I felt faint after donating blood recently (I have low blood pressure) and they have a standard piece of foam to lift your legs up while lying on a bed.

I kept wondering how he got her to the hospital... did they walk?

If the bed is up against a wall, it could easily be the easiest way to shift her back onto the bed.
