Perguntas Frequentes: Aparelhos de Pressão

1 - When do I have to change the batteries of my blood pressure monitor?

A: When you switch on your blood pressure monitor the display will show all the segments testing the device and if by any chance any of them is not working properly the problem will be identified at this moment. One of the symbols is the battery being represented by a horizontal rectangle with 1/3 of its area filled in black color. This symbol does not change at this moment, i.e. it will never be completely full or empty. The battery low indicator will appear on the display only when the battery is low.

2 - Which is the correct position to read blood pressure using wrist type devices?

You should proceed as follows:  

Sit down, both feet on the floor, support your elbow on a table and slightly open your left hand with the palm up.  Position the arm so that the device is exactly at heart level as  in figure A. If there is no support available, sitting or standing up, position the device at heart level with the left arm slightly touching your chest. Keep the body in the upright position and gently support your arm with the right hand during the measurement, as in figure B. Measuring blood pressure lying down: position the arm at heart level as in figure C.

3 - Can I measure repeatedly to confirm the readings?
A: For better results establish an interval of 15 – 20 minutes between readings (for the same user).

4 - My device inflates several times – is this a problem?
A: The digital blood pressure monitor features automatic repressurization. If the initially applied pressure is not enough, the device will inflate again until the measuring is done. This does not indicate any problem.  Put the wrist cuff with care: not too tight, but it must be properly fitted on the wrist leaving no gap.

5 - How do I read my blood pressure?
A: We recommend to round up/down the readings to make it easier, as the example shown below:


6 - My device must have a problem: it reads only zero  both systolic and diastolic.
A: Check if you pressed M memory button.  You should have pressed .

7 - How do I check the last readings?
A: Your device saves the last readings and if you press M button you will read them again.

4- Which are the recommendations to keep my scale functioning well?

A: The scale must be kept on flat, hard surface and never on rugs, carpets or irregular surfaces because this can induce to wrong readings.
