Common factors of wrong measurement

• Please keep quiet for 5-10 minutes and avoid eating, drinking alcohol, smoking, exercising and bathing before taking 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).

• Take measurement regularly at the same time of every day, as blood pressure changes even during the day.

• All efforts by the patient to support their arm can increase blood pressure.

• Make sure you are in a comfortable, relax position and do not activate any of the muscles in the measurement arm during measurement. Use a cushion for support 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 reading.

• 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 512 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

Low blood pressure
Normal blood pressure| systolic <100 diastolic <60 (green display area **18**)
systolic 100 – 139 diastolic 60 – 89
---|---
Forms of hypertension
Mild hypertension| (yellow display area **18**) systolic 140 – 159 diastolic 90 – 99
Moderate hypertension| (orange display area **18**) systolic 160 – 179 diastolic 100 – 109
Severe hypertension| (red display area **18**) 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, remove it and insert the 4 AA LR6 type 1.5 V 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.

   Press SET button **5** to confirm the date, then computer will switch to time setting mode.

4. Time setting:
   The hour starts flashing. Keep pressing the MEM-button **3** until the required hour appears. Press SET button **5** to confirm the hour and proceed in the same way for minute setting. Afterwards CL appears in the display. You can quit set-up mode by pressing SET button **5**
   If the batteries are changed the information is lost and the date and time need to be set again.

Fitting the cuff

1. Push the end piece of the air tube 7 into the hole on the left side of the unit prior to use.
2. Slide the open end of the cuff through the metal bracket so that the Velcro fastener is on the outside and it becomes a cylindrical form (Fig.1). Slide the cuff over your left upper arm.
3. Position the air hose in the middle of your arm in line with your middle finger (Fig.2) (a). The lower edge of the cuff should be 2 – 3 cm above the crease of the elbow. (b). Pull the cuff tight and close the Velcro fastener. (c).
4. Measure the pulse on your bare arm.
5. Only position the cuff on the right arm if it cannot be used on the left arm. Always carry out measurements on the same arm.
6. Correct measuring position for sitting (Fig.3).

Taking a blood pressure measurement
After the cuff has been appropriately positioned,the measurement can begin:

1. Switch the unit on by pressing the START/STOP button **4**.

2. If the START/STOP button **4** is pressed, two short beeps are heard and all display characters are shown (display test). This test can be used to check that the display is indicating properly and in full.

3. The unit is ready for measurement and the number 0 flashes for 2 seconds. It automatically inflates the cuff slowly in order to measure your blood pressure. The rising pressure in the cuff is shown on the display.

4. 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.

5. 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 with the pulse symbol appear on the display **8**. The blood pressure indicator flashes next to the relevant coloured bar depending on the blood pressure classification. If the unit has detected an irregular heartbeat, the arrhythmia display also flashes.
   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.

6. The readings are automatically saved in the selected memory ( or ). Up to 90 measured values with date and time can be stored in each memory.

7. The measurement readings remain on the display. The unit switches off automatically after approx. 3 minutes if no buttons are pressed. The unit may also be switched off using the START/STOP button **4**.

Discontinuing a measurement
If it is necessary to interrupt a blood pressure measurement for any reason (eg. the patient feels unwell) the START/STOP button **4** can be pressed at any time. The device immediately decrease the cuff pressure automatically.

Displaying stored values
This unit features 2 separate memories, each with a capacity of 90 memory slots. Results are automatically stored in the memory selected by the user. Press the MEM button **3** when power off, to call up the measured values stored. All values average appear on the display. Pressing the MEM button **3** again, the last measurement value will be shown. Repeatedly pressing the MEM button **3** displays the respective values measured previously. If you have reached the final entry and do not press a button, the unit automatically switches itself off after approximately 120 seconds in memory recall mode. Memory recall mode can be exited at any time by pressing the START/STOP button **4** , which will also switch the unit off. The oldest value is deleted if 90 measured values have been stored in the memory and a new value is saved.

Deleting stored values
If you are sure that you want to permanently remove all stored memories, press the SET button **5** for 7 times until CL appears when power off. Press the START/STOP button **4** , CL will flash for 3 times to clear all the memories. After this press MEM button **3** , M and “no” will be shown on the display which mean that no memory in store.
