I have one and I also have a full-function patient monitor at home, as well as having an investigational CPR device originally fabricated as a "spare" for a clinical study.

I have these as a consequence of the work I used to do (well...I still do a bit of consulting...), but as I've gotten older I've realized the value of having these available. Having a known accurate BP & pulse ox pleth monitoring is good for one's peace of mind, and every month or so I check my own EKG because of a family history of afib and other issues.

By the way, the 4-7 minutes quoted above is a good estimate. I've also seen 3 to 10 minutes, but shorter is, of course, better and points to the need to start CPR quickly.
