What Causes Variation In Blood Pressure?

When taking blood pressure reading, the machine will give me a reading, when I retake it, it gives me a totally different reading than the first reading. I take the reading again, I will get a totally different reading again. I have changed the batteries in the machine, and it still give me different reading every time I reset the machine.Is my blood pressure going up and down like that?

Hello there
I am happy to be able to answer your query

Digital Blood pressure equipment are mostly accurate.. but can vary due to some variables such as

the sensor being aligned with the brachial artery

holding of breath by patient sometimes

patients position /arm position

Therefore an up/ down of a few mm should not matter mostly

Hope this satisfies your query.
