What are teacher's supposed to do when a student faints?

I just had an appendectomy last Saturday and still feeling kind of 'off' so to speak. In Biology today we were watching a movie that showed a lot of blood. I (hating blood) started to feel quite light-headed and dizzy. Then I started to feel warm and it seemed that the lights were fading, and I really don't remember much after that, other than fainting. My Biology teacher did absolutely nothing to help (that's what everyone in my class said). My lab partner was the one to help me 'wake' up and after that my teacher only sent me to the nurse. Aren't like teachers suppose to know what to do when something like this happens?
