Common factors of wrong measurements

Please keep quiet for 5-10 minutes and avoid eating, drinking alcohol, smoking, exercising and bathing before taking a measurement. All these factors will influence the measurement result.
Remove any garment that fits closely to your upper arm.
Always measure on the same arm (normally left).
Measurements should be taken regularly at the same time of each day, as the blood pressure varies even during the day.
Any effort to support the arm during measurement may increase the measured blood pressure.
Make sure, you are in a comfortable, relaxed position and do not move or constrict your muscles during measurement. Use a cushion to support your arm if necessary.
If the arm artery lies lower or higher than the heart, a false reading will be obtained.
A loose or open cuff causes false readings.
With repeated measurements , blood accumulates in the arm which can lead to false reading.
Consecutive blood pressure measurements should be repeated after 1 minute pause or after the arm has been held up in order to allow the accumulated blood to flow away.

What is blood pressure?
Blood pressure is the pressure created in the blood vessels by each heart beat. When the heart contracts (= systole) and pumps blood into the arteries, it brings about a rise in pressure. The highest value is known as the systolic pressure and is the first value to be measured. When the cardiac muscle relaxes to take in fresh blood, the pressure in the arteries also falls. Once the arteries are relaxed, a second reading is taken – the diastolic pressure.

How is blood pressure measured?
The medisana BU 530 is a blood pressure unit which is used to measure blood pressure at the upper arm. The measurement is carried out by a microprocessor, which, via a pressure sensor, measures the vibrations resulting from the inflation and deflation of the cuff over the artery.

Blood pressure classification WHO

These values have been specified by the World Health Organisation (WHO) without making any allowance for age.

Low blood pressure
systolic <100 diastolic <60
Normal blood pressure
(green display area )
systolic 100 – 139 diastolic 60 – 89
Forms of high blood pressure / hypertension
- Mild hypertension
  (yellow display area )
  systolic 140 – 159 diastolic 90 – 99
- Moderate hypertension
  (orange display area 19 ) systolic 160 – 179 diastolic 100 – 109
- Severe hypertension
  (red display area 19) systolic ≥ 180 diastolic ≥ 110

WARNING

Blood pressure that is too low represents just as great a health risk as blood pressure that is too high! Fits of dizziness may lead to dangerous situations arising (e.g. on stairs or in traffic)!

Influencing and evaluating readings

Measure your blood pressure several times, then record and compare the results. Do not draw any conclusions from a single reading.
Your blood pressure readings should always be evaluated by a doctor who is also familiar with your personal medical history. When using the unit regularly and recording the values for your doctor, you should visit the doctor from time to time to keep him updated.
When taking readings, remember that the daily values are influenced by several factors. Smoking, consumption of alcohol, drugs and physical exertion influence the measured values in various ways.
Measure your blood pressure before meals.
Before taking readings, allow yourself at least 5-10 minutes rest.
If the systolic and diastolic readings seem unusual (too high or too low) on several occasions, despite correct use of the unit, please inform your doctor.
This also applies to the rare occasions when an irregular or very weak pulse prevents you from taking readings.

Starting up

Insert / replace batteries
You must insert the batteries provided before you can use your unit. The lid of the battery compartment 6 is located on the underside of the unit. Open it by slightly pushing it and moving it upwards. Remove it and insert the 4 AAA LR03 type 1.5V batteries supplied. Ensure correct polarity when inserting the batteries (as marked inside the battery compartment). Close the battery compartment. Replace the batteries if the change battery symbol 14 appears on the display 8 or if nothing appears on the display after the unit has been switched on.

Using a Mains Adaptor
Alternatively, you can use the unit with a special mains adaptor (medisana Art.- No. 51125). This connects to the socket 1 provided at the back of the unit. In this case the batteries remain in the unit. Inserting the connector into the back of the blood pressure monitor switches the batteries off mechanically.
It is necessary, therefore, to plug the mains adaptor into the mains socket first of all and then to connect it to the blood pressure monitor. If the blood pressure monitor is no longer being used, first remove the connector from the blood pressure monitor and then pull the mains adaptor out of the mains socket. Doing this means that the date and time will not have to be reset each time.

Taking a blood pressure measurement

After the cuff has been appropriately positioned, the measurement can begin:

Switch the unit on by pressing the START/STOP button 4.
If the START/STOP button 4 is pressed, all display characters are shown (display test). This test can be used to check that the display is indicating properly and in full.
The unit is ready for measurement. The number 0 flashes for 2 seconds and two short beeps are emitted. The device then automatically inflates the cuff slowly in order to measure your blood pressure. The rising pressure in the cuff is shown on the display.
The unit inflates the cuff until sufficient pressure has built up for a measurement. Then the unit slowly releases air from the cuff and carries out the measurement. When the device detects the signal, the heart symbol on the display starts to flash, you can hear the beep for every heartbeat once the heartbeat signal is detected.
When the measurement is finished, you can hear a long beep and the cuff is deflated completely. The systolic and diastolic blood pressure and the pulse value appear on the display 8. The blood pressure indicator 19 is displayed next to the relevant coloured bar depending on the WHO blood pressure classification. If the unit has detected an irregular heartbeat, the arrhythmia display 15 also appears.
WARNING
Do not take any therapeutic measures on the basis of a self measurement. Never alter the dose of a medicine prescribed by a doctor.
The readings are automatically saved in the previously selected memory ( or ). Up to 120 measured values with date and time can be stored in each memory.
The measurement readings remain on the display. The unit switches off automatically after approx. 30 seconds if no buttons are pressed. The unit may also be switched off using the START/STOP button 4.

Transfer via Bluetooth to VitaDock+ app
