fitnesskelly Posted September 28, 2015 Report Share Posted September 28, 2015 I've looked all over the internet for this info and can't find much.I assume it's normal for someone with a normal functioning BP to be pretty consistent from sitting or laying to standing and to stay consistent over time?

navyblue Posted September 28, 2015 Report Share Posted September 28, 2015 laying to standing- normally bp initially drops a little bit (bc everyone's blood pools somewhat in the feet when first standing) and then in a matter of seconds it'll go back up, sometimes a little over the initial laying down level.It's tough to measure this though. Technically for an accurate measurement you're not really supposed to take your blood pressure while standing because gravity plays a role and it will be deceptively high if your arm is hanging down. Best to have something you can rest your arm on so that it is at heart level. Quote Link to comment Share on other sites More sharing options...
bigtrouble Posted September 28, 2015 Report Share Posted September 28, 2015 From what I understand, veins have valves that act as a door ways so that blood flows in one direction but don't quote me on that. Perhaps I am thinking of bats, which is what makes it possible for them to hang upside down for hours. Quote Link to comment Share on other sites More sharing options...
