When Cole has had a seizure at school, they call me. If I called 911 every time he was having a seizure, I'd feel like I was abusing the system.
At his school, we have a very detailed seizure plan in place, and everyone who comes into contact with him knows his trigger (right now it's just lack of sleep/being fatigued) and Pre-seizure behaviors. They call me immediately even if they just think he's having one and don't know for sure.
Down here, you can arrive by ambulance all you want, but you'll get dumped in the ER alongside everyone else. When Carson had the skull fracture and major concussion, we arrived via ambulance....and we're deposited in the pediatric ER with all the ear infections and sniffles. It wasn't until I was voicing my complaints and he started vomiting everywhere with his eyes rolling back in his head (not a seizure) that we were pushed to the head of the line.
As for this school, Renee said exactly my first thoughts: they're damned if they do, damned if they don't.
And what is this school's policy? Did the parents choose to have them be called first? I know, at Cole's school, you dictate what order you want things done (although they say they will call 911 first in the event of an extreme emergency).
Oh, and Carson's EMS ambulance bill was $768. Not exactly chump change.
