I read that the machine , and your arm should be level with your heart.
I also checked my blood pressure at home 123 / 78.
I had a 60 kilometre drive to the hospital . The blood pressure machine wasn't on a table , it was a stand up one on wheels.
The machine towers above the seated patient and the arm has to rest on your lap.
155 / 93 was my reading. I talked to them about the arm , machine and heart inline , and they didn't understand , gave one of those nervous laughs and wanted to give me tablets.
I refused , got back home and checked my pressure , it was 125 / 83.
