BP monitor - how to check calibration?
I have the doctors panicking over my high blood pressure. So I dug out
a digi BP monitor we had for a few years #1. That had a problem with its over pressure safety valve, which I repaired whilst waiting for a new one to be delivered. It's readings were completely inconsistent, so today (still waiting for #2 to arrive), I went out and bought an over the counter #3. #3 (a cuff auto digital) seems to provide consistent values, no rapid wild variations, but how to be sure the displayed readings are correct? I have already been advised that any of the larger pharmacists should have a device to check the calibration of BP monitors, but I wonder if there might be a way to check it at home? |

That might explain it. #1 is a wrist type, #2 when it arrives will be a wrist type, #3 is a upper arm cuff type speced to be accurate to +/- 3 mmHg. |

Malcolm Race laid this down on his screen :
Take it to the Surgert and compare the reading with one taken immediately afterwards with a surgery machine. I have what the doctor describes as 'White coat syndrome' Me too, to some extent, even when I measure it myself :-? Apressure os say 1292/120 translates into n143/90 at home. When I go in I take a series of recent reaqdings with me. That is my plan, but I tried that a couple of weeks ago and the values I noted were way below correct values, down in the normal range. I'm keen not to repeat providing them with erroneous data, hence my question of how to check the calibration at home to be sure. |

Malcolm I hope you mistyped that first one ;-) As an aside, I happened to meet someone involved in the design of a new type of BP meter. He told me the 'cuff type' was generally accepted to be potentially wildly inaccurate - there are too many things in the basic set up which are not controlled- eg initial cuff fit, the point where the user detects the 'change' (I can't recall the correct term he used), ...... While I accept he had reasons to criticise the 'old' approach (he was working on the replacement), he knew I wasn't a customer and his points did make engineering sense. He didn't share details of the replacement, other than it worked by sensing flow as far as I could tell. |

Is your machine an upper arm cuff type? The wrist type are notoriously inconsistent. That's what I have read. I also note that when some of these wrist devices are being demonstrated that the wrist has to be placed over your heart (the monitoring point has to be at the same level as the heart). I have two upper arm devices, from different manufactures[1*], and they both give nearly the same reading when comparing BP tests 2 minutes apart. I also have a 'sports' bracelet https://www.amazon.co.uk/Cospor-Wire.../dp/B06XZ6HLRR which measures pulse rate and blood pressure by flashing LEDs at the skin. When connected by way of Bluetooth to a smart phone while this is happening the waveform being analysed can be seen. This ALWAYS reads low by 15 to 20mmhg compared to my upper arm monitors so cannot be trusted BUT as it takes regular readings throughout the day/night I can see the trend when my BP rises/falls, synchronised to the time when I take my daily BP medication. [1*] http://www.argos.co.uk/product/6167662 https://www.amazon.co.uk/Omron-Press...omron+m10+-+it The smaller Argos/Kinetik is easier to carry around while the larger Omron has more features that I don't really need. -- mailto: news {at} admac {dot] myzen {dot} co {dot} uk |

Not really I went to my Gp to do mine. Mine is a talking one but its bedside
manner is, erm a little too casual. According to the who guidlines you blood pressure is high to normal, or whatever, though of course it gives the figures and stores them in a continuously rotating memory historically. All I will say is don't let them prescribe Ramopril, as it gives you a nasty cough. there are other medications to dilate blood vessels that work just as well. However they really need to find out why the pressure is high. In my case its my liver being hard to push blood through, but I'm sure there are lots of other issues.

Brian Gaff expressed precisely :

However they really need to find out why the pressure is high. In my case its my liver being hard to push blood through, but I'm sure there are lots of other issues. Brian I have to take one of those per day, beginning last Thursday -I don't have a cough. They began me on Amlopodine 1 per day, 18 days ago. I don't think the Ramopil dilates, the Amlopodine was supposed to do that - so they said. |

BP monitor - how to check calibration?
RJH has brought this to us :
My succession of doctors have absolutely no interest in cause - or at least an easily identified cause from a basic annual blood test. The current doctor's opinion is 'it's one of those things'. You may be right, they gave me a tablet to 'take as necessary' to control the vertigo. I tried it all ways and it had no effect, didn't help at all, but I was promised they would try to address it better, once my BP was under control. Last evening, I decided to do some research on the cause(s) of vertigo. I intend trying the fixes suggested online. I documented it for a friend, using none tech terms... http://www.chiropractic-help.com/Hom...r-vertigo.html It is also called Brandt-Daroff exercise, this... http://www.webmd.com/brain/brandt-da...-vertigo-16844 https://www.youtube.com/watch?v=voZXtTUdQ00 http://www.med.umich.edu/1libr/PMR/V...onExercise.pdf The NHSs version of the method.. http://www.ncuh.nhs.uk/our-services/...uick-guide.pdf The flickering left and right of the eyes, is called nystagmus. That caused by your brain trying to make sense of the confusing signals from your eyes, versus the conflicting signals from your benign paroxysmal positional vertigo from the canals behind your ears. Eyes say you are the right way up, your ear sensors say you are leaning at an odd angle. I have had a few bouts of nystagmus, when the vertigo has been at its worst. Loose particles in the canal flow at a different speed past the filament sensors in the canals, compared to the fluid, confusing the receptor filaments in the canal causing them to send confused signals. The idea of the exercises is to let these particles fall by gravity, to places in the canal where they will not cause a problem. Sometimes the particles can stick to the sides of the tube, so they help these to loosen by using some skull vibration. |

Last time I ended up in ER with very intense stomach pain the bugger managed to put a cannula into my wrist so professionally that I didn't even notice he had done that until after he had done it. I was just giving him the history etc. And I didn't pass out and notice when they do a cannula normally. |

He told me the 'cuff type' was generally accepted to be potentially wildly inaccurate - there are too many things in the basic set up which are not controlled- eg initial cuff fit, the point where the user detects the 'change' (I can't recall the correct term he used), ...... While I accept he had reasons to criticise the 'old' approach (he was working on the replacement), he knew I wasn't a customer and his points did make engineering sense. He didn't share details of the replacement, other than it worked by sensing flow as far as I could tell. I can confirm that. I was discovered to have high blood pressure while in hospital for something else. I always wonder if a given cuff will give accurate results for both fat and skinny arms. Lidl had a recent offer of a wrist-cuff meter for only £10 which I bought, but I found that the readings varied erratically from one to the next. When plotted on a graph my average systolic is 140 which is "good" (compared with the doctors' arm-cuff readings of over 180) but the peaks and troughs were about plus and minus 40 on that, so I gave up using it. When I was in hospital having arm-cuff readings every 6 hours, they also varied wildly from sample to sample. -- Dave W |

According to the who guidlines you blood pressure is high to normal, or whatever, though of course it gives the figures and stores them in a continuously rotating memory historically. All I will say is don't let them prescribe Ramopril, as it gives you a nasty cough. there are other medications to dilate blood vessels that work just as well. I think it varies with the individual. I take amlodipine and, swollen ankles aside for the first couple of months, no side effects. Except to say I haven't had a hangover or headache in the 6/7 years I've been taking it. You'd think there'd be a Nobel Prize in there somewhere, but the doc doesn't seem interested :-) However they really need to find out why the pressure is high. In my case its my liver being hard to push blood through, but I'm sure there are lots of other issues. My succession of doctors have absolutely no interest in cause - or at least an easily identified cause from a basic annual blood test. The current doctor's opinion is 'it's one of those things'. There are some known causes they check for- renal stenosis and the artery in your neck. If they check clear, it is usually put down to 'essential hypertension' - not quite one of those things but some people are prone to it. |

So I dug out a digi BP monitor we had for a few years #1. That had a problem with its over pressure safety valve, which I repaired whilst waiting for a new one to be delivered. It's readings were completely inconsistent, so today (still waiting for #2 to arrive), I went out and bought an over the counter #3. #3 (a cuff auto digital) seems to provide consistent values, no rapid wild variations, but how to be sure the displayed readings are correct? I have already been advised that any of the larger pharmacists should have a device to check the calibration of BP monitors, but I wonder if there might be a way to check it at home? I supply a service to pharmacies, or at least did so before I retired earlier this year and I never saw such a calibration device or service offered. My late father was a medical rep in the 1960s and carried a little bottle of Hg to top up doctors traditional sphigs, so I suppose that was a calibration service. Is your machine an upper arm cuff type? The wrist type are notoriously inconsistent. That might explain it. #1 is a wrist type, #2 when it arrives will be a wrist type, #3 is a upper arm cuff type speced to be accurate to +/- 3 mmHg. I bought a Boots upper arm type. very consistent and agreed well with doctor's -- Microsoft : the best reason to go to Linux that ever existed. |

Yes white coat syndrome is no more than a normal case of being very nervous near any kind of medical person who is about to pronounce you ill! That is why they usually take more than one reading to allow you to calm down a bit. Brian best practice before treating "high blood pressure" is to have a 24hour BP monitoring test done. My BP is always much higher at the surgery than at home and more interestingly the 24 hour monitoring initially showed the same BP as at home and then even lower BP for the rest of the 24hours. Just taking my BP seems to have and adverse effect. I suspect that white coat syndrome is not uncommon. Whatever the accuracy of monitors used at home, their main use is to show changes over time so absolute accuracy is not important. |

Brian I have to take one of those per day, beginning last Thursday -I don't have a cough. They began me on Amlopodine 1 per day, 18 days ago. I don't think the Ramopil dilates, the Amlopodine was supposed to do that - so they said. I too am on Amlodipine and Ramipril. I was expecting the cough for the latter, but no, it only affects 10% of patients according to the leaflet. Nobody knows why the elderly get high blood pressure, which makes me dubious about taking pills to reduce it. Both these medications relax the blood vessels so that the heart doesn't have to pump so hard and is under less strain. It sounds plausible but I can't find any evidential studies to prove it. I could argue that if the blood vessels are expanded, their walls would be thinner and weaker, and might burst at a lower pressure. So although my blood pressure is lower, my chances of having a stroke are the same! When I was searching for academic papers, I came across an outfit called Cochran. Their mission is to create an index of independent global medical evidence on all sorts of topics. One is the question of whether giving medication for mild hypertension to the elderly increases their chances of survival. They could find nothing much, so I gave up looking also. -- Dave W |
