thanks for that..i had been looking at that site earlier and then forgot the name of it. Was looking at the Nonin.
I need one that is known to be reliable.. as in tested... since I already have a blood oxygen issue.
will search around on what they have
i am not spending this much money on a system..but I could see where this might be suitable for elderly or other situations..it has a video camera. so in theory, you could check in on your grandpa and see his vitals IF you could do it by phone remotely
