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 their am happy to be able to answer your queryDigital 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 positionTherefore an up/ down of a few mm should not matter mostly Hope this satisfies your query.  Stay healthy . Keep smiling
