Measuring blood pressure Note: To guarantee that you will be able to compare values adequately, always measure your blood pressure at the same time of day. Rest for approx. 5 minutes before every measurement! If you wish to undertake multiple measurements on the one person, wait for 5 minutes between taking each measurement. You should not eat, drink, smoke or be active in the 30 minutes before each measurement. Repeat the measurement process if the measured values seem incorrect.60 GB/IE Bring the device to room temperature before the meas- urement. Attaching the cuff ATTENTION! The device may only be used in conjunc- tion with the original cuff provided. The cuff is suitable for an arm circumference between 22 and 36 cm. Place the cuff

on a bare upper left arm (Fig. D). The blood flow of the arm should not be constricted by clothing which is too tight, etc. The cuff

should be placed on the upper arm in such a way that the lower edge lies 2–3 cm over the crook of the arm and the artery. The cuff tubing

points to the centre of the palm. Place the free end of the cuff

closely, but not too tightly, around the arm and close the Velcro strip. The cuff

should not be too tight (Fig. E). Check that two fingers can still fit beneath the cuff

into the connector (Fig. G). Adopting the correct posture Note: Stay still during the measurement process and do not talk to prevent the measurement result from being falsified.61 GB/IE You can carry out the measurement while sitting or lying down. Always ensure that the cuff

is at the same level as the heart (Fig. H-J). Sit comfortably for the blood pressure measurement. Recline your back and arms. Do not cross your legs. Put your feet flat on the ground. In order not to falsify the measurement result, it is impor- tant that you stay still and do not talk. Selecting a memory Press the SET button

Evaluating Measurements Cardiac arrhythmia This device can identify any potential cardiac arrhythmia disorders and, if necessary, indicates this after the measure- ment process with the symbol . This can be an indicator for arrhythmia. Arrhythmia is an illness in which the heart rhythm is abnor- mal due to errors in the bioelectric system, which controls the heartbeat. The symptoms (skipped or premature heart- beats, slow or rapid pulse) can stem from heart conditions, age, physical predispositions, an excess of luxury foods, stress or a lack of sleep. Arrhythmia can only be diagnosed by a doctor after a physical examination. Repeat the measurement process if the symbol is shown on the display after the measurement. Please guarantee that you rest 5 minutes before the measure- ment and do not talk or move during it.65 GB/IE If the symbol is displayed repeat- edly, contact your doctor. Self-diagnosis and self-treatment on the basis of measurement results can be dangerous. Follow your doctor‘s instructions. Classification of measurement results In accordance with the guidelines / definitions provided by the World Health Organisation (WHO) and the latest find- ings, the measurement results can be classified and evalu- ated according to the following table: Range of blood pressure values Systole (in mmHg) Diastole (in mmHg) Remedies Stage 3 se- vere hyper- tension ≥ 180 ≥ 110 seek medical attention Stage 2: moderate hypertension 160–179 100–109 seek medical attention Stage 1: mild hypertension 140–159 90–99 regular monitoring by a doctor High, normal 130–139 85–89 regular monitoring by a doctor Normal 120–129 80–84 Self-monitor66 GB/IE Range of blood pressure values Systole (in mmHg) Diastole (in mmHg) Remedies Ideal < 120 < 80 Self-monitor Source: WHO, 1999 Note: These standard values merely serve as a general guideline as blood pressure deviates depending on the individual, different age groups, etc. It is important that you consult your doctor at regular intervals. Your doctor will give you your particular values for normal blood pressure as well as the value for when your blood pressure is classified as dangerous. The bar chart on the display and the scale on the device state which range the blood pressure measured is in. If the systole and diastole values are in two different ranges (i.e. systole is „high, normal“ and diastole is „normal“) the graphic categorisation on the device will always show the higher range i.e. in the above example this would be „high, normal“. Saving, requesting and deleting measurements The results of each successful measurement are saved together with the date and time. If there are over 3067 GB/IE measurement values, the oldest measurement value will be overwritten. Press the SET button
