While there may be some physical explanation of the effect of cuff pressure
on MM's blood pressure "readings", does anyone know more about what
blood pressure _is_ than the definition of what it takes to cut off and
restore circulation? Are my arteries "springier" (say) -- more responsive,
maybe even healthier -- if I'm 120/100 than if I'm 120/90? What are the
limits -- how long would I have lasted at 60/40 (lying down)? Doesn't it
depend on a balance between the pressure of the "pump" and the elasticity of
the walls of the "pipes"? Don't they communicate and coordinate in other
ways than pressure (hormones, ANS, electrolytes,...)? Do I have to jog, or
will ERG do it? And how sensitively do that cuff and that dial indicate
(resistance to) failure modes in such a system? (Modulo, perchance, the
attendant's coefficient of sycophanticity.)
