I do better lying down when taking my blood pressure. Probably because these places are so disorganized and unprofessional. Does PRA make you sit or lay down for blood pressure?
I dont know about PRA, but on my first study, I found there is a 3rd way: semi-supine(the term amused the heck out of me...I was 1 out of 2 patients in the whole clinic right before a holiday, so I needed things to be amused by, and other folks' work jargon tends to do it for me!). Anyhow, I've only had the semi supine and fully lying down, in my very limited experience so far.
On that note, my heart rate was 56 bpm when they checked vitals for my last check in, so I'm kind of worried it may make me TOO relaxed(50 was the lower cutoff).
