Proper use

This fully automatic electronic blood pressure monitor is intended for measuring the blood pressure at home. It is a non-invasive blood pressure measurement system to measure the diastolic and systolic blood pressure and pulse of an adult using a non-invasive technique by means of a cuff, which needs to be fitted on the wrist.

Contraindications

The device is not suitable for measuring the blood pressure of children. Ask your doctor before using it on older children. Persons who suffer from arrhythmia, diabetes, cardiovascular problems or who have had a stroke should consult their doctor before using the device.

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 watches or other spruce from your wrist before measurement.
Always measure on the same wrist (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 wrist is not at heart level, a false reading may be obtained.
A loose or open cuff causes false readings.
With repeated measurements, blood accumulates in the wrist, what may lead to false readings. Consecutive blood pressure measurements should be carried out after a 5-minute pause or after the arm has been held up in order to allow the accumulated blood to flow normally.

Safety Instructions

Read the instruction manual carefully before using this device, especially the safety instructions, and keep the instruction manual for future use. Should you give this device to another person, it is vital that you also pass on these instructions for use.

The unit is intended only for use in the home. Consult your doctor prior to using the blood pressure monitor if you are concerned about health matters.
Only use the unit for its intended purpose in accordance with the instructions for use. Warranty claims become void if the unit is misused.
Please consult your doctor prior to using the unit if you suffer from illnesses such as arterial occlusive disease.
The unit may not be used to check the heart rate of a pacemaker.
Like on any other oscillometric blood pressure measurement devices, certain medical conditions can affect the measurement accuracy, among others: cardiac arrhythmias, low blood pressure, circulatory disorders, states of shock, diabetes, pregnancy, pre-eclampsy etc. Always consult a physician before you use the device.
This device is not suitable to provide a medical diagnosis. The measurement results are for reference only. Contact your physician to get information about
treatment and medicine, which are necessary for you.
The arrhythmia function does not replace a professional cardiac examination. Check with your doctor if any treatment or medical action is necessary for you.
A heartbeat that varies by 25% or more from the average of all heartbeats during a measurement may cause difficulties to determine the correct blood pressure.
The “Blood pressure classification WHO” is not suitable to replace a medical diagnosis. Ask your physician to individually evaluate your blood pressure.
If you experience discomfort during a measurement, such as pain in the wrist or other complaints or in case the device does not stop to inflate the cuff, press the – button to release the air immediately from the cuff. Loosen the cuff and remove it from your wrist.
Blood pressure measurements in high repetition rates may lead to unwanted side effects, e.g. nerval compression or blood clots.

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 BW 310 is a blood pressure unit which is used to measure blood pressure from the wrist. 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 2/21 ) systolic 100 – 139 diastolic 60 – 89

Forms of high blood pressure / hypertension

Mild hypertension (yellow display area 2/21 ) systolic 140 – 159 diastolic 90 – 99
Moderate hypertension (orange display area 2/21 ) systolic 160 – 179 diastolic 100 – 109
Severe hypertension (red display area 2/21 ) 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. i
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 battery compartment 1 is located on the left-hand side of the unit. Open it by pushing the cover outward and remove it. Insert the 2 AAA LR03 type 1.5 V batteries supplied. Ensure correct polarity when inserting the batteries (as marked on the battery compartment cover). Close the battery compartment. Replace the batteries immediately, if the partial change battery symbol 9 flashes on the display 3 and “E6” is appearing at the same time or if nothing appears on the display after the unit has been switched on. If the partial change battery symbol 9 appears on the display constantly together with “E6”, the batteries are already in poor condition. If the full change battery symbol 9 appears, the batteries are in good condition.

There should be a gap of approx. 1 cm between the cuff and the palm of the hand (fig.2).
Press the Velcro tape firmly around the wrist ensuring that it is not so tight that it could falsify the measured result (fig.3).

Correct position for taking readings

Carry out the measurement whilst seated.
Relax your arm and place it comfortably, on a table for instance.
Raise the wrist so that the cuff of the monitor is at heart level (fig. 4, position a = too high, b correct, c = too low).
Keep still during the measurement: Do not move and do not talk as this may alter the measurements.

Taking a blood pressure measurement

After the cuff has been appropriately positioned,the measurement can begin: 1. Switch the unit on by pressing the – button. The measurement will also start immediately.
The unit is ready for measurement and the average value of the last 3 measurements and the last memory slot number shortly appear. The device 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 measurement. Then the unit slowly releases air from the cuff and carries out the measurement. When the device detects the signal, the heart symbol starts to flash on the dis-play.
When the measurement is finished, the cuff is deflated completely. The list and diastolic blood pressure and the pulse system display. The blood pressure indicator is shown next to the relevant coloured bar depending on the WHO blood pressure classification. If the unit has detected an irregular heartbeat, the arrhythmia display 18 will also alue appear on the be shown.
WARNING
Do not take any therapeutic measures on the basis of a self-measurement. Never alter the dose of medicine prescribed by a doctor.
The readings are automatically saved in the selected memory (1 or 2 ) Up to 60 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. 2 minutes if no buttons are pressed. The unit may also be switched off using the – button 7.

Discontinuing a measurement
If it is necessary to interrupt a blood pressure measurement for any reason (eg. the patient feels unwell) the – button 7 can be pressed at any time. The device immediately decreases the cuff pressure automatically.
