So I went for an appointment at my GP surgery to try and verify the accuracy of two home blood pressure monitors we have in our house. The two monitors give virtually identical readings to each other for everyone in our family - but for my sister one reads 10 - 15 points lower than the other on thr systolic number.
During the appointment, my sister attempted to explain the situation and that she wanted to compare both machines against a manual reading. The nurse immediately told her to "just bin" one of the machines without any attempt to even compare it
The nurse then proceeded to only check one of the machines (the one that reads lower). When the machine displayed a reading of 150/100, she then performed a "manual check" and literally immediately stated "yeah 150/100". Might be just me, but this rapid confirmation seems like the nurse was simply just re-stating the reading she had seen on the machines screen (literally told me her reading was the exact same number) rather than conducting a genuine, independent manual verification. Her pre-judgement of which machine was correct was evident from the beginning, as she refused to consider checking the second machine, despite my clear explanation of the discrepancy of both machines for me, but identical readings for the rest of the family
As a result, I was left in the exact same position I was in before the appointment. I actually suffer from anxiety and came back in tears at how sharp and unhelpful she had been, and because it seemed she had made her mind up there and then she was only checking one machine and that was the correct one (despite them giving the same readings for everyone else), i don't trust what she told me at all
