When you start saying "some", you are on a slippery slope. Laws must be very precise, or they will mutate on you. You're right, the airways might make some of us a little nervous, but I've never known anyone who knew what they were who was unable to make the go/no-go call on thier own. BP cuffs, unless you try to use one as cervical collar or to control the bleeding of a head wound, really are pretty much harmless. Everything else you can get without an Rx is dual use stuff, as I said before.
Jim, I think you are seeing problem where they really don't exist.
