Perhaps a more interesting third dimension would be

my doctor's office is just a small desktop thing running Windows and a
bunch of software from EPIC, but the automagic blood pressure cuff
with the nifty graphical display the nurse uses to take my vitals is
something else entirely.
Everyone forgets about embedded systems. When I was still noodling,
there were several RTOSes that were POSIX-certified (QNX and VxWorks,
amongst others). Of course, these ran on the higher end 32-bit MCUs, of
which dozens exist in modern cars. That medical stuff probably conforms
to IEC 62304, regardless of its internals.
