So would you provide mouth-to-mouth to a stranger? Here's why I'm asking. I learned CPR in high school and was quite enthused about the whole idea. Then I worked at a couple of jobs where they emphasized "universal precautions," a mindset where, in handling industrial accidents, you assume everyone is positive for everything and protect yourself accordingly from blood spills and open wounds. Also I recently found out someone (family friend) who I wouldn't have thought twice about giving CPR to has a highly contagious, chronic disease, which was sort of a shocker even though we all *know* anyone could have anything. Now I'm in a state of considering whether I would endanger my family's health by performing this lifesaving service. I'm going to buy one of those one-way valve devices, but I know the situation might come up where I would have to put my mouth on a stranger and risk their saliva, blood, or vomit entering my body. What do you think you would do? What ethics would you apply in this situation? By the way, I just asked an attorney and he said (in Texas, at least) there is no affirmative duty to perform emergency care, and Good Samaritan Law protects you from criminal and civil liability if you do provide it. So it's totally up to you, legally speaking.
