I live in an apartment building with adaptations for the disabled, so I meet quite a few people with various disabilities in my wanderings. At a dinner in the building I met a person with a blood pressure of 67/40 (at least that is what she said). Admittedly she is about to go on a waiting list for a heart transplant, but I am blown away that someone with blood pressure that low can be walking around and lucid!
How low can someone’s BP go and still be able lucid and ambulatory?
