My moms blood pressure has been raising and its 175/98 and her face is really red. How high does it take to stroke or should I just take her to the hospital?

Is she taking any blood pressure medication?

I would take her to the ER -- or call an ambulance. They will stabilize her as much as they can before she gets to the ER..
