Struggling to understand when to call ambulance for a seizure

My gf had her first 2 seizures within the past 24 hours. After witnessing both, I have called ambulance as it is a new occurrence for her. She was hospitalized both times, the second time she was prescribed keppra to take twice a day.

For those whose partners have epilepsy, or generalized seizures. What did you tell to your significant other to do when having a seizure. Her neurologist has said it’s best to call ambulance under certain circumstances, for example, if she had a seizure longer than 5 minutes, has trouble breathing, bleeding, etc.

Witnessing her seizures both times has really scared me and makes me want to call 911 immediately if I were to witness another seizure. Her post seizure state where she is confused after worries me because I’ve been told that it could last hours or even days, although hers has only lasted about 20-25 minutes each time.

For those who have had multiple seizures before, what is your usual protocol in activating an emergency system or calling 911.
