Re: Pre-med physics in practice

We have a physician's word that this effect does not occur. Why not?

Good grief! We have a physician's explanation that --

Which of course is nonsense.

From an experimental physicist's point of view there is not much point in
debating the issue -- just take B/P with the arm over the head and then
again at the hips all whie standing!

And do it with a manual sphig and cuff - the automatic ones are commonly
off by several percent! Of course when I suggested this to a nurse
recently, she became a bit (a lot) miffed until the physician did it
manually and found the reading off by 20mm -- of course she didn't know
what it was 20 of -- had no idea that it was 20mmHg and how that was a
measure of pressure -- medical offices are dangerous!

BTW I have commonly given the cuff position question on the final to
classes of nurses. Physics should be a required course for all medical
people -- it is the only place they will learn some of the important stuff
-- levers, sound, nerve conduction, thermo, fluids, nuclear radiation -- if
this is left to med or nursing school, they will get the silly stuff that
physicians and others offer in their columns.

And that some physicists assume is true!
