My father lives very far away and just suffered a stroke. I need to find a way where he can wear a watch or some sort of device that monitors his blood pressure and where I can see his progress remotely. He lives by himself and desperately trying to find a solution.
If I had to buy a commercial device for a very important use like the one you describe I would probably spend the money on something like this: Smart Blood Pressure Monitors by Withings.
It’s obviously much more expensive than a regular blood pressure cuff. However, I have used various Withings products and currently use their connected scale, and I think they are likely to be reliable and not too painful to set up.
You can connect the cuff to a cheap dedicated phone, if you don’t want to bother your dad with this, and then you can set up the app to share the data with you.
I’d set up the withings device to work with his @swimmerguy dad’s wifi. Then sign up for a health practitioner account with heads up here: headsuphealth
Then connect withings to the Heads Up account and it will automatically sync the data to the dashboard for him. If he wanted to track his dad’s scale, steps/movement, sleep, and more he can do that as well. The remote patient monitoring dashboard from Heads Up is highly flexible and easy to configure. I attached my dashboard here as an example. BP bottom left hand corner. .
