Selecting the correct cuff

The WatchBP Home device is available with different cuff sizes. If you believe the cuff size provided with your device is incorrect, please consult your doctor.

please use only Microlife cuffs!

Taking measurements using WatchBP Home
Prior to each measurement, use the Mode Switch on the side of the device to select the proper measurement mode. The two options include: «DIAG.» (Diagnostic) or «USUAL» (Usual) mode.

«DIAG.» Mode
The «DIAG.» mode should be selected when blood pressure is to be measured in accordance with measurement guidelines of the European Society of Hypertension (ESH), and as requested by your doctor.

No measurements on non-work days
In «DIAG.» mode, blood pressure measurements are taking on 7 consecutive working days (or normal week days). No readings should be taken on «non- working» days (or particularly relaxing days) in this mode!

Two sets of measurements per day
ESH guidelines recommend to take two measurements in the morning between 06:00 – 09:00 and two measurements in the evening between 18:00 – 21:00. Always take measurements before taking your medication, unless otherwise directed by your doctor.

Extended measurement period
WatchBP Home has an extended measurement period and allows morning measurements between 04:00 – 12:00 and evening measurements between 18:00 – 24:00.

Evaluation
After measurements have been carried out for a total of 7 working days, bring the device to your doctor for evaluation of your home blood pressure.

«USUAL» Mode
The «USUAL» mode should be selected when blood pressure is to be measured independent of recommended guidelines. In «USUAL» mode, single measurements can be taken at any time, and results are automatically stored for later evaluation by your doctor.
250 measurements safely stored
The WatchBP Home device can store up to 250 single measurements in «USUAL» mode. When memory is full, each new measurement will automatically overwrite the earliest measurement.

Eight steps for taking proper blood pressure

1. Step 1
   Avoid taking measurements directly after eating, drinking, or smoking. Allow at least one hour between these activities and measurement of your blood pressure.

2. Step 2
   Prepare a chair and table for the measurement. The chair should have a vertical back-rest and the table should allow for your upper arm to rest at the same height as your heart.

3. Step 3
   Remove all clothing covering or constricting the measurement arm. Apply the cuff. Make sure the lower edge of the cuff is 2–3cm from the inner fold of your arm. The tube connecting the cuff to the device should be placed on the inside of the arm.

   • (Additional visual instruction can be found on the cuff)

4. Step 4
   Sit down and relax for at least five minutes prior to the measurement.

5. Step 5
   Sit upright and lean comfortably against the chair’s backrest. Press the start button. The device will initiate a 60-second countdown. During the measurement do not move, cross your legs, or tense your arm muscles. Breath normally and do not talk.

6. Step 6
   One measurement cycle includes two measurements. Once the first measurement is complete, continue to relax as you wait for the second measurement. The second measurement will start after 60-seconds. During this time avoid movement.

7. Step 7
   Once the two readings are complete, measurement data are automatically stored for future reference by your doctor. If an error displays after the readings, please repeat the first six steps once again.

8. Step 8
   When seven days of measurements have been collected, the Doctor Symbol will flash on the display. Do not forget to bring your WatchBP Home device with you on your next doctor visit. (Note: the doctor symbol is only displayed for measurements in «DIAG.» Mode.)

Viewing, deleting and transferring measurements

Viewing measurements

1. Use the Mode switch to first select the type of measurements you wish to view.
2. Then press the M Button.

In «DIAG.» Mode

1. When the M Button is pressed, it briefly displays the total number of measurements stored, e.g. N=20.
   • «A» is displayed when the number shown is the average of all data.
   • • «- -» will display when the number of measurements is less than 12.
2. Pressing the M Button again displays the average of all morning data.
3. Pressing M Button once again shows the average of all evening data.
   All individual readings can be viewed by repeatedly pressing the M Button.

In «USUAL» Mode

1. When the M Button is pressed, it briefly displays the total number of measurements stored, e.g.N=63, followed immediately by the average of all measurements stored in memory.
2. All individual readings can be viewed by repeatedly pressing the M Button.

Deleting measurements

• Data from «DIAG.» and «USUAL» can be deleted independent of each other.
  • Before deleting data, be sure to ask your doctor if the measurement data are still required. Only delete the stored measurements when you are sure that you no longer need the data.

1. Use the Mode switch to first select the type of measurements you wish to delete.
2. Press the M Button and hold it until the delete symbol flashes.
3. Release the M Button and press it once more while the delete symbol flashes. Deletion is confirmed by the beep sound.
   • Only measurements in the selected mode will be deleted. Measurement data in the other mode must be deleted independently.
   • Pressing the M Button to delete data will erase all measurement data in the selected mode.

too weak. Re-position the cuff and repeat the measurement.
« Er 2 »| Error signal| During the measurement, error signals were detected by the cuff, caused for instance by movement or muscle tension. Repeat the measurement, keeping your arm still.
« Er 3 »| No pressure in the cuff| An adequate pressure cannot be generated in the cuff. A leak may have occurred. Replace the batteries if necessary.

Repeat the measurement.

---|---|---
« Er 5 »| Abnormal result| The measuring signals are inaccurate and no result can therefore be displayed. Read through the checklist for performing reliable measurements and then repeat the measurement.
« HI »| Pulse or cuff pressure too high| The pressure in the cuff is too high (over 300 mmHg) OR the pulse is too high (over 200 beats per minute). Relax for 5 minutes and repeat the measurement.
---|---|---
« LO »| Pulse too low| The pulse is too low (less than 40 beats per minute). Repeat the measurement.

Important facts about blood pressure and home measurements

• Blood pressure is the pressure of the blood flowing in the arteries generated by the pumping of the heart. Two data, the systolic (upper) value and the diastolic (lower) value, are always measured.
• The pulse rate is the number of times the heart beats in a minute.
• Permanently high blood pressure data can damage your health and must be treated by your doctor!
• Always discuss your home blood pressure measurement data with your doctor and tell him/her if you have noticed anything unusual or feel unsure. Never rely on single blood pressure readings.
• There are many causes of excessively high blood pressure readings. Your doctor will explain them in more detail and offer treatment where appropriate.
• Blood pressure is subject to wide fluctuations as the day progresses, and can be impacted by emotions, physical exertion and other conditions .

Evaluating blood pressure data
The table at right classifies blood pressure data for adults in accordance to the guidelines of the European Society of Hypertension (ESH) in 2007. Data in mmHg. The higher value is the one that determines the evaluation. Example: a readout value between 150/85 or 120/98 mmHg indicates «Grade 1 Hypertension».
