Species better throbbing values gives with the physics behind the principle of "pressure" to make the point is short; it means that the height of the heart and the location of the measurement, should be equal.
When the measurement is below the heart level is being executed, there is, namely an additional column of liquid (the vein, filled with blood), which exerts additional pressure (due to the force of gravity), so that the measurement gives a higher blood pressure than is actually true. This risk is much greater wrist blood pressure monitors, whatever the reason is that these models are not recommended.
In addition to the above differences, can also separate brands and models still have many differences? In order to make clear that the British Hypertension Society, the BHS, has developed a score running from A to D, with being the highest and D is the lowest score.
Keep this then definitely in mind when purchasing a blood pressure monitor and prefer not to buy models with no or very low BHS score.
Also note certificates, recommendations and approvals from other organization. This way there is less risk that you come home with a product that does not work as you expected over a thousand kilometers with a capacity of five to six liters vital. All facts that apply to your circulatory system;
the presence of this system, which is next to the heart too many giant (stroke) includes veins and capillaries, ensures that all the organs in your body can do their job properly.
