Welcome to the forums. It's both good and responsible of you to learn what to do in the case of an emergency. The common rule of thumb if some has gotten to the point of passing out is to call 911 and get professional attention. Most of us carry Glucose Tablets, which will raise our sugar levels when we go low, other "quick fixes" include drinking something like orange juice as sometimes people are too "out of it" to eat. It would help if you could tell us more about your boyfriend, how low do his levels go, how does he normally treat going low, how does he behave when he goes low -some people become "difficult" to handle when they are low. I would think that it would not be unreasonable to ask your boyfriend to show you how to use his meter and test him and then ask him how best to help him when he goes low. It would also be good for you to know what medication he uses so that if you call 911 you have that information for them.
