I purchased a new blood pressure monitor the other day. It says that for the most accurate reading, I should rest for 15 minutes, not eat or drink for 30 minutes and have my legs resting on the floor. How can this represent an accurate measurement of BP? Is it just a limitation of the automated machines? I believe that I’ve seen similar instructions on other monitors.
I think that this is the right forum since I’m not asking for medical advice but if a mod disagrees, I won’t object.
