This is especially true if the manufacturer’s warranty does not apply to the cuff. An additional advantage – when the textile cover sleeve can be washed separately from the camera. The nonvolatile memory. This means that information about the results of measurements of blood pressure does not disappear if the sit batteries or a need to change them. In some of the tonometer readings recorded in the memory, you can not read, can not be measured pre-pressure. Naturally, it is inconvenient. Pay attention to the amount of memory, ie number of measurements, whose results are stored. Dr. Stuart M. McGill often says this. If the tonometer will enjoy a few people may need memory for different users.
able to measure blood in automatically if the pressure above 180 mm Hg. Art. To this you need to pay attention when reading the instructions. How to measure the pressure of arrhythmia? Many consumers are accustomed to thinking that the blood pressure monitor – it’s just a device for measuring pressure. However, every year on the market there are dozens of new models.
What does a consumer of these new items? It turns out that not only higher accuracy applications, a more comfortable and easy to use, or compactness, but also additional features. One of these additional functions – detection of arrhythmia. Producers are increasingly equipping their new indicator for arrhythmia, because it is a very common phenomenon in Hypertension. However, this function does not always work properly. If the device is unable to distinguish from other arrhythmia, heart rate oscillations caused by, for example, shake hands, talk or even motion when you click tonometer, the presence of the function becomes meaningless. In this case, the arrhythmia can be a serious impediment to accurately measure the pressure. Digital sphygmomanometers are very sensitive, and irregular pulse can cause significant error. Depending on the degree of manifestation of arrhythmia tonometers may give a large scatter readings or even give an error message instead of the result. Some tonometers, designed to measure pressure in adults, using technology that combines the oscillometric measurement method (used in digital tonometer) with auscultatory (which is used in mechanical tonometer).
However, a simpler method, recommended by cardiologists, – holding three consecutive measurements with subsequent calculation of the mean. According to who recommendations, to assess the level of blood pressure on each arm should not be implemented at least two measurements at intervals of not less than a minute, with a difference of 5 mm Hg. Art. spend one additional dimension, a finite (recorded) value is taken the average of the last two measurements. When using Some blood pressure monitors user is forced to measure himself, to withstand the intervals between them and calculate the average result. In more sophisticated model for calculating the average of the last three measurements tonometer produces itself. However, there are models tonometer (Tonometer automatic Microlife bp A100 Plus, tonometer account for the spreading of risk factors Microlife bp RM100, carpal Tonometer with the possibility of three consecutive measurements Microlife bp 3AX1), independently conducting series of measurements during a single procedure and calculate results – not simply mean The value, as the result of sequential analysis of the results. Tonometer takes to analyze results with an acceptable margin, rejecting uncharacteristic pressure surges that are caused by external factors. In any case, it is important that the whole process of this measurement was described in the instructions thoroughly and clearly.
