My husband is 74, with a shunt in his brain. I had trouble waking him up this afternoon! His BP is 148/84, pulse 60, at the moment. It took cold water on his face and pounding on his chest to get him awake. I am freaked out. Should I take him to the ER? He's wide awake now, but I'm scared. It happened about four days ago, too, but it wasn't nearly as bad as this time.
