The lungs probably represent a future ability to check your blood O2 saturation which is something else that can be done via an IR sensor through the skin in your fingers.

A wrist based blood pressure monitor is fine for watching trends towards something bad happening. You can also get wrist units that come with computer software that downloads the raw data from the unit and crunches it to detect irregular heart beats and other issues the tiny CPU in the monitor can’t detect.

I personally use an Omron HEM-670IT at work. On bad days I’m checking every hour.

First, the power button in on the left.

Second, I want to know the difference between turning the heart off with the power button and using the exit door on the right. They would seem to do the same thing, though perhaps the exit door makes the final result come faster?

Hope all is well with the family. Take care,
David

Upper arm monitors are generally supposed to be more accurate than wrist-based BP monitors.

Seems like an interesting gadget though..
