Blood Pressure
To determine your blood pressure, two values have to be measured:
- SYS – systolic (upper) blood pressure – this is generated when the heart contracts and blood is pumped into the blood vessels.
- DIA – diastolic (lower) blood pressure – this is produced when the heart relaxes and fills up with blood again.
The measured values for blood pressure are displayed in mmHg.
To better evaluate the results, Veroval® blood pressure monitors offer a traffic light colour system that directly describes the results to enable easier categorisation of the measured value. The World Health Organisation (WHO) and the European Society of Cardiology (ESC) & European Society of Hypertension (ESH) have developed the following summary for classifying blood pressure values:
| Results indicator | Evaluation | Systolic pressure | Diastolic pressure | |
| Red | Grade 3 hypertension | above 179 mmHg | and/or | above 109 mmHg |
| Orange | Grade 2 hypertension | 160 - 179 mmHg | and/or | 100 - 109 mmHg |
| Yellow | Grade 1 hypertension | 140 - 159 mmHg | and/or | 90 - 99 mmHg |
| Green | High normal | 130 - 139 mmHg | and/or | 85 - 89 mmHg |
| Green | Normal | 120 - 129 mmHg | and/or | 80 - 84 mmHg |
| Green | Optimal | up to 119 mmHg | and | up tp 79 mmHg |
- Established hypertension (high blood pressure) is defined as having a systolic value of at least 140 mmHg and/or a diastolic value of at least 90 mmHg.
- Generally, blood pressure is described as being too low (hypotension) when the blood pressure value is less than 105 mmHg (systolic) and 60 mmHg (diastolic). However, the threshold between normal and low blood pressure (hypotension) is not as accurately specified as the threshold for high blood pressure (hypertension). Hypotension may be indicated by symptoms such as dizziness, tiredness, tendency to faint, visual disorders or a high pulse rate. In order to ensure that hypotension or the associated symptoms are not signs of a serious illness, a doctor should be consulted in the event of doubt.

- Measures using the oscillometric method
Blood pressure measurement can be performed by two methods: the auscultatory or traditional method and the oscillometric method.
The auscultatory or traditional method determines blood pressure by monitoring Korotkoff sounds with an inflatable rubber cuff around the upper arm at approximately the same vertical height as the heart, usually attached to a mercury manometer. The cuff is manually adjusted and inflated by squeezing a rubber knob, until the artery is completely occluded (about 30 mmHg above systolic pressure). The cuff pressure is then slowly released. As blood begins to flow through the artery, the turbulent stream creates a synchronous pulsation of the pulse (first Korotkoff sound). The pressure at which this sound is first detected is the systolic blood pressure. The cuff pressure continues to be released until no sound can be detected, when the diastolic blood pressure is obtained. The Veroval® duo control, although not a manual mercury manometer, follows the same principle by determining the blood pressure by monitoring the Korotkoff sounds.
The oscillometric method uses an electronic pressure sensor with a numerical blood pressure reading. In most cases the cuff is inflated and released by an electrically operated pump and valve which can be adapted to the wrist (raised to the level of the heart), although the arm is preferred. The cuff is initially inflated to a pressure above the systolic blood pressure, and then the pressure is lowered below the diastolic pressure. Once blood flow is resumed, but limited, the cuff pressure will vary periodically in synchronisation with the cyclic expansion and contraction of the brachial artery. Systolic and diastolic pressure values are calculated from the raw data using an algorithm.

Many factors play a role in blood pressure measurement. The ten general rules help you to measure correctly.
Veroval® Compact Upper Arm Blood Pressure Monitor
Please read the instruction leaflet carefully before using your Veroval® product for the first time, since correct blood pressure measurement requires correct operation of the device. These instructions will guide you through the individual steps for measuring your own blood pressure. You will be given important and useful hints to ensure that you obtain reliable results for your personal blood pressure profile.
Many factors play a role in blood pressure measurement. These ten general rules help you to measure correctly.
- Avoid nicotine and alcohol for an hour before measuring your blood pressure.
- Do not drink any coffee immediately before measuring it.
- Ensure your bladder is empty. A full bladder increases blood pressure by about 10 mmHg.
- Do not measure if you are under stress, in pain or afraid. These factors affect blood pressure.
- Ensure when measuring that the cuff is put on in the right place. If you wish to measure your blood pressure with the upper arm device, the edge of the cuff must be 2.5 cm above the bend of the elbow. If using a wrist device, the correct site of measurement is 1 cm above the wrist.
- When positioning the wrist or upper arm, ensure that the site of measurement is at heart level; if the position deviates by about 1.5 cm, the blood pressure changes by + 1 mmHg.
- Relax your arm muscles during measurement. Tensing the muscles increases the blood pressure by about 10 mmHg.
- Do not talk during the measurement. Conversation during measurement can increase the blood pressure by about 6-7 mmHg.
- The upper arm must not be constricted by clothing when measuring with an upper arm device. The best thing is to remove all clothing from the upper arm.
- Check before measuring that you have applied the upper arm cuff correctly. If you can push two fingers under the edge of the cuff, you can start measuring. A cuff that is too loose or too tight gives readings that are too high or too low respectively.
- Have a rest for one minute before you repeat the measurement.
- Remember that blood pressure levels are subject to a characteristic diurnal rhythm, and can change according to the time of day and the daily demands at that moment. To obtain comparable readings, the best thing is always to select the same time for taking the reading.
Veroval® Wrist Blood Pressure Monitor
Stroke Prevention
Atrial fibrillation is the most common cardiac arrhythmia and can only be detected when it occurs. It is characterized by a markedly accelerated, constantly irregular heartbeat. When atrial fibrillation occurs, the atria can no longer properly support the heart chambers during pumping. As a result, the heart does not empty completely and blood remains in the atria, where it can form clots. These clots can enter the brain and trigger a stroke.
Signs of atrial fibrillation are often unspecific, such as palpitations, dizziness, shortness of breath or chest pain. Up to 30 % of the people who suffer from atrial fibrillation do not feel any symptoms at all.
2 in 1 Veroval® ECG and Blood Pressure Monitor
Stroke prevention is especially important for people over the age of 50, or people suffering from hypertension, diabetes or hyperlipidemia. In general, there are two important factors which are accountable for heart attacks and particularly strokes: these are high blood pressure and irregular heartbeat, particularly atrial fibrillation.
Therefore, our Veroval® combination device is the ideal monitoring product to check those factors regularly. The good news is that more than 80 % of strokes can be prevented. Beside some non-influencable risk factors, such as old age, being male, family history or having already suffered a stroke, you can reduce your stroke risk by:
- Taking charge of your own health and living a healthy lifestyle: eat healthy, stay active, avoid smoking and drinking too much alcohol.
- Managing your blood pressure, ECG, cholesterol and diabetes.
- Taking your medication as recommended by your doctor.
Talk to your doctor about your stroke risk and set up a prevention plan that’s individually tailored for you.
The Veroval® ECG and blood pressure monitor is a single channel ECG that can detect various arrhythmias – for example atrial fibrillation, extrasystoles – and therefore helps to make a preliminary assessment by carrying out a basic recording.
- If status messages repeatedly deviate from the norm, it is recommended to undergo a medical examination.
- Regardless of the measurement result, the patient must immediately seek medical treatment by a doctor if he/she notices any symptoms that may indicate acute heart disease.
Recording a 1-lead ECG is not a substitute for medical treatment! The device is not a substitute for either a medical examination of heart function, nor recording of a medical electrocardiogram, which must be obtained using more elaborate measuring equipment. The device does not diagnose any medical conditions that may be the possible cause of the change observed in the ECG.
The 2 in 1 Veroval® ECG and blood pressure monitor stores up to a total of 128 ECG and/or blood pressure readings, including the date and time of the measurement (64 readings for each of the 2 users). The most recently measured value is displayed first, and the oldest last. Once all memory slots are occupied, the oldest value is deleted.

Veroval® Fever 2 in 1 Infrared Thermometer
The Veroval® Fever 2 in 1 infrared thermometer offers two different ways of taking temperature: in the ear and on the forehead. It is possible to select between the two modes according to preference. You can set it to take either ear or forehead temperature readings by using the mode switch on the side of the thermometer. With only 1 second (or the duration of the scanning procedure for forehead measurement) the temperature is taken very fast. Using the supplied single-use protective covers ensures that taking a temperature in the ear is especially hygienic, and the risk of transferring bacteria or viruses is greatly minimise.
Further advantages:
- Ear mode measurement in a second
- Fast and easy temperature measurement
- The infrared thermometers from HARTMANN have been developed in Germany with the HARTMANN quality assurance guidelines. Designed to meet customer needs, they meet high stability standards
- Smooth, safe and hygienic measurement by using disposable protective covers
- Easy cleaning of the measuring sensor
- High measuring accuracy
- The high measuring accuracy of the infrared thermometer has been proven in clinical studies
- Memory function: The infrared thermometers from HARTMANN store up to 10 readings in the memory function, simplifying overviews of fever progression.
- Optical fever indicator: If the body temperature shown on the screen is 37.6 °C or higher, the screen will light up red as a visual alert to indicate a fever
- Recommended for clinical use, recommended for home use
The Veroval® Protective Covers are intended to be used together with the Veroval® 2 in 1 infrared thermometer. In combination with the thermometer, the disposable protective covers allow a very hygienic measurement of body temperature in the ear. The single-use product helps to prevent cross-contaminations and infections by transmission of bacteria or viruses. The product is made of smooth plastic with clear membrane, and is free of DEHP and latex.
You’re also welcome to watch our video about the usage of the protective covers.
Veroval® Baby 3 in 1 Infrared Thermometer
The thermometer measures the infrared radiation emitted by the skin on the forehead and the temple area and by the surrounding tissue. The radiation is picked up by the sensor and converted into temperature values. The highest measurement recorded is displayed on the device.
Similarly, if the temperature measurement is carried out as a surface measurement of an object or as a room temperature measurement, the sensor detects the radiation emitted from the surface of the object respectively of the ambient air in the room.
Contact free infrared thermometers use a modern measuring sensor technology to provide a body temperature value of high measurement accuracy. It is the most advanced and safest method of measuring the body temperature currently on the market. It is convenient as well as easy to use.
A non-contact forehead thermometer allows measurement of the temperature of babies, children and adults to be taken without skin contact in only 3 seconds. The thermometer is simply moved across the forehead over the temporal artery: a positioning light integrated into the head of the sensor enables guided handling of the thermometer during the scanning process. This eliminates the need to physically insert a probe into a body cavity such as the ear canal or rectum, which is not always well received by very sick children and babies. When a non-contact thermometer is used, you can take your child‘s temperature even while he or she is sleeping, absolutely silently and without bothering or even waking him or her.
Contact-free body temperature measurement is safe and hygienic because the temperature is measured without skin contact. The risk of contact transmission of bacteria or viruses is minimized. Therefore Veroval® Baby is ideal for use on babies and children.
Veroval® Baby additionally allows the measurement of the surface of an object or the room temperature in a further measuring mode. It can therefore be used in multiple ways.
Weight
An unbalanced diet with a lot of fat food is one of the main risk factors that can influence hypertension. It is also proven that a healthy diet can contribute to the normalisation of blood pressure.
With the help of Veroval® weighing and smart scale, a body analysis can be included in the long-term documentation and linked with other vital values. Measurable success also motivates and encourages your compliance to a healthy lifestyle!
The Veroval® Scale has 4-Memory functions for 4 family members. It stores up to 30 measurements for each user memory. The oldest measured value is always stored at memory position number 1 and all newer stored values shift up by one memory position. Once all memory slots are occupied, the oldest value is deleted.
The measured data can be conveniently stored. In addition, the values can be analysed and shared by e-mail or PDF-printout with the doctor. A further advantage is that the values can be crosslinked to the data of other Veroval® devices for example the blood pressure monitor, thus enabling a comprehensive health analysis that can assist your doctor in his or her therapy recommendation.
Veroval® Scale
The Veroval® Scale operates using the principle of bioelectric impedance analysis (BIA). Determination of body composition is made within seconds using this technique. Using this measurement of electrical resistance (impedance) and including other constant or individual values (age, height, gender, degree of activity), body fat content and other contents in the body can be determined. Muscle tissue and water have high conductivity and therefore a low resistance. Bone and fat, on the other hand, have low conductivity because the fat cells and bone tissue barely conduct any electricity because of their high resistance. The values determined by the weighing scales represent only an approximation of the medical, real analysis values of the body. Only a specialist doctor can precisely determine the percentage of body fat, body water, muscle percentage and bone mass using medical methods (e.g. computer tomography).
Ideal weight is very individual. A guideline for the ideal weight is to use the mean of the BMI for normal weight (21.75) relative to the person’s height: 21.75 × height in m2 (example: 21.75 kg/m2 × 1.8 m2 = 70.47 kg).
The active metabolic rate (AMR) is the quantity of energy that the body consumes each day in its active state, that is, the calorie requirements in kcal per day used for activity. The energy consumption of a human rises with increasing physical activity and is determined by the level of activity (1 – 5) entered into the scales. If over a longer period less energy is supplied in the form of nutrition than is consumed, the body essentially obtains the difference from its fat stores and weight decreases. If, however, more energy is supplied than the calculated active metabolic rate (AMR) over a longer period, the body cannot burn up the excess energy. The excess is stored by the body as fat and weight increases.
The values for the body fat are shown on the display and assessed as ‘low’, ‘normal’, ‘high’ or ‘very high’ and depend on your age and sex. The percentage of body fat is normally within the following ranges (please contact your doctor for more information):
Keep in mind that a lower value is often measured for athletes. Depending on the type of sport, the intensity of training and your physical constitution, values can be measured that are further below the guidelines indicated. Please note that there may be health risks associated with extremely low values.
The percentage of body water is normally within the following ranges:
The muscle percentage is normally within the following ranges:
Like the rest of our body, our bones undergo natural processes of growth, breakdown and ageing. Bone mass increases rapidly during childhood and reaches its peak between 30 and 40 years. As you age, your bone mass starts to gradually decline. If you have a healthy diet (particularly calcium and vitamin D) and regularly exercise, you can slow this process down. You can also strengthen the stability of your skeletal structure using targeted muscle growth.
Please note that Veroval® scale does measure minerals of bones. The scale does not identify the calcium content of the bone, but rather the weight of all bone components (organic substances, inorganic substances and water). There are no recognized guidelines and recommendations available.
Do not confuse bone mass with bone density. Bone density can only be determined using a medical examination (e.g. computed tomography, ultrasound). Drawing any conclusions about changes to the bone and bone hardness (e.g. associated with osteoporosis) is not possible using this scale.
The body mass index (BMI) is a figure that is often used to assess weight. The number is calculated from the values for the weight and height using the following formula:
Body Mass Index = weight ÷ height2. The unit for the BMI is therefore [kg/m2]. Weight is classified using the BMI for adults (aged over 20 years) with the following values
Clean and Disinfect
Only use a damp cloth to clean the scale. If required, you can spray a little cleaner on the cloth. Do not use any aggressive cleaners and never immerse the scale in water.
Do not clean the scale in the dishwasher!
The electrodes must not be cleaned with alcohol or disinfectant.
With the Veroval® smart scale, body parameters such as weight, BMI, bone mass, body fat, muscle and water can be determined and analysed. The intelligent scales also automatically calculate calorie requirement and ideal weight. The clear to understand display is detachable and connected wirelessly to the scales, so that the displayed values are easy to read. With the Veroval® medi.connect software all values can be stored, graphically processed, shared and combined with other Veroval® devices.
