DURING HIGH BLOOD PRESSURE

WHAT TO DO DURING HIGH BLOOD PRESSURE?

• Change your way of life, create your own ladder of values so that health comes first.
• Reduce mental stress – reduce too many activities, do not perform more than one at a time, avoid time constraints, always have sufficient time reserve when meeting deadlines. Increase the support of your immediate surroundings, especially in the family, with friends and colleagues.
• Increase relaxation activities – include in your program regular walks, passive rest and enough sleep, warm and bubble baths, self-relaxation techniques, recreational sports, non-stressful hobbies.
• Include in your weekly program at least 3 x 40 minutes of endurance exercise (brisk walking, swimming, cycling, cross-country skiing) at a pulse rate of 50-70% of the maximum, in the presence of other diseases as recommended by a doctor.
• Do not smoke.
• Reduce the salt content of the food, avoid foods and beverages with a high salt content such as e.g. sausages, preserved and instant meals or certain mineral waters.
• In your diet, prefer foods high in fiber and vitamins, especially fruits, raw and cooked vegetables, whole grains, low-fat dairy products (cheeses with a fat content of less than 30% in dry matter), reduce the intake of animal fats (butter, rye, red meat and fishery products), increase the intake of fish and fishery products, do not fry, steam. When overweight, reduce caloric intake and increase energy expenditure.
• With a high alcohol intake, reduce its consumption to a maximum of 2-3 dl of wine per day, or 0.3 – 0.5 l of beer, or 0.04 dl of distillate.
• Make lifestyle changes gradually, not all at once. Focus on one or two changes and only when they are fixed, focus on the next.
• Take your blood pressure regularly at home at the same time in the morning and in the evening, calculate the average values from the measured values. The aim is to achieve average values lower than or equal to 135/85 mmHg. Use only approved pressure gauges type.

Using the pressure gauge

• The sphygmomanometer measures human systolic, diastolic blood pressure and pulse in the arteries in the shoulder. It uses an oscillometric measuring method.
• We recommend that only persons over the age of 18 use the device. The device is intended for domestic use.
• It is not intended for professional clicker use.

BLOOD PRESSURE INFORMATION

Blood pressure

The heart works like a pump, and it pumps blood that flows through the arteries all the time. The result is blood pressure on the walls of the arteries. When blood flows out of the heart, we talk about systolic blood pressure, and when blood returns to the heart, we talk about diastolic blood pressure.

Blood pressure fluctuations

Blood pressure fluctuates during the day. Its value is higher during the day than in the evening. The lowest value is around midnight. Blood pressure starts to rise again around 3 o‘clock in the morning and reaches its highest value during the day, so it is not possible to measure the same data every time.

Systolic blood pressure

Diastolic blood pressure:

Knowledge of blood pressure

There are a number of factors, such as body conditions or measurement problems, that can affect blood pressure. For example, some people may be nervous when they see a doctor, which causes their blood pressure to rise. This case is well known as „white coat hypertension“. Random measurements do not determine the overall blood pressure level and therefore there is no reason to worry at isolated higher or lower blood pressure levels. The most important thing is to monitor the development of your blood pressure by long- term measurement. In Western countries, people measure their blood pressure at home and pass the results on to their doctor so that they can better assess their high and low blood pressure. You can obtain baseline values by measuring over several days at the same time of day. These data are called “baseline blood pressure“.

Mean arterial blood pressure values (mmHg)

Hypertension

Hypertension can be caused by various cardiovascular diseases, kidney diseases and endocrinopathies. Long-term hypertension can lead to pathological changes in the heart, brain and kidneys. These changes can lead to hypertensive complications known as “hidden killers.“

Complaint

Hypertension is one of the diseases of civilization and its pathology is still unclear. The key problem with hypertension is prevention, such as eating less salty foods, more vegetables and fruits, not smoking and paying more attention to a balanced diet, etc.

Why measure your blood pressure?

We recommend home blood pressure measurement as a preventive measure and as a standard supplement to the treatment of hypertension at your doctor. The advantage of measuring your blood pressure at home is that you can monitor your blood pressure regularly at a given time and in normal everyday conditions. This avoids the danger of an artificial increase in values caused by nervousness in a foreign medical office environment (so-called office hypertension, white coat effect, etc.).

People can also measure their blood pressure themselves

It is not easy to find out exactly what a person‘s blood pressure is. The measurement itself is not demanding, but the pressure fluctuates immensely, it changes with literally every heartbeat after physical or mental exertion – this can be, for example, a visit to the surgery. The pressure measured in the outpatient clinic is usually slightly higher than that which the patient normally has. The pressure is usually lowest during sleep, rising in the morning, highest in the morning, and decreasing after lunch. For someone, it will rise slightly for the evening. The difference may not only be between parts of the day, it is also common for the pressure measured on both hands to differ.

The solution? More frequent measurements.

Another solution is home measurement, whether occasional or 24-hour monitoring. However, even monitoring awareness can increase someone‘s pressure above normal. That is why the World Health Organization recommends that this monitoring be carried out several times in six months if hypertension is 13EN suspected. It wants to prevent unnecessary administration of drugs to someone who does not really need them. If you intend to measure the pressure at home yourself, you should avoid the classic mercury device. The content of toxic mercury, as well as the complexity of the measurement, should be a sufficient argument why to withdraw from its purchase.

Regular daily pressure measurement

Many people have a good reason to measure pressure outside the doctor‘s office. Higher blood pressure poses a risk of a number of dangerous complications, but subjectively no one feels it. The so-called automation, i.e. measuring the pressure outside the doctor‘s office to the patient himself, is of great importance in preventing these complications – such as myocardial infarction, stroke and many others.

Is blood pressure measurement difficult?

No, not at all. Electronic blood measuring instruments pressure on the arm and wrist are so easy to operate that it is very difficult to make a mistake when using them. They are therefore very suitable for driving both at home and on the road or in the office. However, in order to obtain comparable values, the following rules must be observed: always measure the pressure at the same time of day, after ten minutes of a quiet sitting position. Note that the measured values are affected by circumstances such as smoking or drinking coffee.

IMPORTANT INFORMATION

BEFORE USING THE DEVICE

• Consult your doctor about pressure measurement.
• Blood pressure is changing! It is affected by a number of different factors such as smoking, alcohol consumption, medication and physical activity. Do not eat, smoke or exercise for at least 30 minutes before starting the blood pressure measurement.
• Do not drink blood pressure before starting the measurement.
• Stress increases blood pressure, so do not measure under stressful conditions.
• Rest for at least 5 minutes before starting blood pressure measurement.
• Wrap the cuff around your wrist when measuring. It is recommended that the cuff of the blood pressure monitor be placed on the left wrist.
• Do not shake the instrument during the measurement. Otherwise, the measured data may not be correct. The measurement should be performed in a quiet place, you should be in a comfortable sitting position with feet on the floor. Leave the left shoulder on the table with the palm facing up so that the cuff is at the same level as the heart.
• Stay calm and do not talk during the measurement.
• Do not wrap the cuff around clothing. The measurement will not be correct.
• People who are disabled (diabetics, kidneys, arteriosclerotic, etc.) should consult the measured values with a doctor and find out about their accuracy.

MEASUREMENT AND READING OF RESULTS

Read and follow the instructions in the Important Information section before using the device and in the Attaching the Arm Cuff section. Do not talk or move during the measurement. The pressure gauge is designed for measuring and storing measured data in memory for 2 people defined as A and B. The model has a memory for 2 people for 199 measurements.

1. When using for the first time, press USER, when the device is switched off, you are prompted to enter an ID (Person A) or (Person B) for measurements. Make your selection with the button / ,. Before performing a measurement or displaying the memory, make sure that you have entered the correct identifier (A or B) that you have registered before starting the device.
2. Press START/STOP. The pressure gauge starts working and a function check is performed. All functions will be shown on the display for about 3 seconds. Then the symbols on the display disappear and the pressure measurement symbol flashes and the cuff is pressurized. If the measured pressure is higher, the cuff is pressurized to a higher pressure. Do not move or talk during the measurement.
3. When the correct cuff pressure level is reached, automatic cuff discharge will begin automatically. When the cuff is deflated, descending numbers appear on the display. The heart symbol will flash based on the oscillation signals(pulse).
4. When the measurement is completed, the remaining air is released. The display will show the systolic values and diastolic pressure in mmHg and a color indication of whether your pressure is low, normal or high. At the same time, the heart rate (pulse/min) is displayed. If a cardiac arrhythmia is detected during the measurement, the arrhythmia indicator will flash after the measurement. After a certain time, the display and the pressure gauge turn off.
