Preface

Microlife WatchBP Ofce (BP3SK1-3B) is an Automated Ofce Blood Pressure
(AOBP) Monitor.

The device is a non-invasive digital blood pressure device using oscillometric
technique and an upper-arm blood pressure cuff to measure systolic and diastolic
blood pressures, pulse rate, mean arterial pressure (MAP) and pulse pressure (PP)
for use in pediatric and adult populations with arm cuff circumference sizes ranging
from 14 -52 cm.

The device can be connected to a computer (PC) running the WatchBP Analyzer
software. The measured patient data can be transferred from the blood pressure
monitor to the PC by means of a USB cable connection or Bluetooth connection.
The Bluetooth 4.2 connectivity allows data transferring from the device to PC,
smartphones or tablet.

The device detects the appearance of atrial brillation during measurement and gives
a warning signal together with the measured blood pressure value if atrial brillation is
detected (optional).

The device provides aortic blood pressure parameters, includes central systolic
blood pressure (cSBP), central pulse pressure (cPP) and central diastolic pressure
(cDBP), non-invasively through the use of a brachial cuff (optional).

Fitting the cuff properly

1 Place the cuff over the upper arm so that the air tube and

artery mark arrow point towards the lower arm. The artery
mark on the cuff must be placed over the brachial artery.

2 Lay the cuff on the arm. Make sure that the lower edge of

the cuff lies approximately 2 to 3 cm ( ¾ to 1 inch) above the
elbow.

3 Wrap and tighten the cuff around the arm.

4 Leave free space with the size of 2 fingers between the arm

of the patient and the cuff. Excessive tightness may cause
venous congestion and discoloration of the limb. If the cuff is
wrapped too loosely, it cannot be inflated properlyproperly,
and the measured values may be inaccurate. Remove all
clothing covering or constricting the measurement arm.
Clothing may interfere with measurement accuracy.

5 Cuffs that do not fit properly may lead to inaccurate readings.

Taking measurement in MANUAL Mode

Select the MANUAL Mode if auscultatory blood pressure measurement is preferred above
oscillometric blood pressure measurement. In MANUAL Mode, the device serves as a
pressure gauge. No oscillometric measurements will be taken. Systolic and diastolic Korotkoff
sounds amust be determined by a stethoscope placed over the brachial artery.

Start inflation – Press the button to start cuff inflation. When the maximum inflation
pressure is reached, the device will automatically begin a linear deflation at a rate of 3 mmHg/
sec as is recommended by the guidelines.

Assess the Korotkoff K1 and K5 sound – when pushing the button during cuff
deflation the cuff pressure at the time of pushing is temporarily stored so that the systolic (K1)
and diastolic (K5) pressures can be seen afterwards. The device can store up to 4 pressures.

Push the button at any time to start fast deation and nish the measurement of MANUAL
mode and show the pressure you have marked. Alternatively, the device quickly deates and
shows the pressures after having pushed the button 4 times, or the cuff pressure has reached
20mmHg during the deation cycle.

After the measurement in MANUAL mode, the device displays all marked cuff pressures for
one minute.

Re-inflate – Push and Hold the Up button during deflation to re-inflate for as long as the
button is held up to a max of 299mmHg. Release the button to continue deflation. Exceeding
299 mmHg will result in an immediate release of cuff pressure and a ‘HI’ Error message.

Deflate faster – Push and hold the button when deflation will releases the pressure in the
cuff faster, at around 8 -12 mmHg/second.

The recommended deflation rate for auscultation is 2-3 mmHg per seconds. Do not assess K1 or K5 sound while holding the M

Special Functions

Screening for atrial fibrillation during blood pressure measurement

The device is designed to screen for atrial fibrillation during blood pressure measurements
(optional) with high accuracy: a sensitivity of 98% and a specificity value of 92%*. If atrial
fibrillation is detected this will be shown in the report.

Verberk et al. Screening for atrial fibrillation with automated blood pressure measurement: Research evidence and practice



recommendations. Int J Cardiol 2016: 465–473.

About Atrial Fibrillation

Atrial fibrillation is a common heart rhythm problem and a common cause of major strokes.
It affects 8% of those 65 years and older and about 20% of all strokes are caused by atrial
fibrillation. Atrial fibrillation is a rhythm problem that can last from a few minutes, to days or
weeks and even years. Atrial fibrillation can lead to the formation of blood clots in the heart.
These clots can break off and flow to the brain causing stroke. One sign of atrial fibrillation is
palpitations. However, many people have no symptoms and therefore may remain undetected
whereas diagnosing atrial fibrillation early followed by adequate treatment can largely reduce
the chance of getting a stroke.

Central blood pressure parameters

The device is designed to assess central blood pressure parameters (optional).

Central blood pressure is the pressure in the ascending aorta, the largest artery that originates
from the left ventricular of the heart and from where oxygen is distributed to all parts of the body
through the systemic circulation. Central Systolic Blood Pressure and Central Pulse Pressure
provided by this monitor are determined directly through pulse volume plethysmography
(PVP) waveform analysis. Central Diastolic Blood Pressure by this monitor is calculated by
subtraction of Central Systolic Blood Pressure and Central Pulse Pressure.

How is central blood pressure measured?

The device measures brachial systolic and diastolic blood pressure as usual. However, where
the cuff normally totally deflates after the blood pressure measurement, the cuff now stops
deflating at approximately 60 mmHg cuff pressure to keep a stable pressure on the brachial
artery for approximately 10 seconds which is needed to acquire brachial pulse volume
plethysmography (PVP) waveforms (pulse volume recording). During these 10 seconds
approximately 10 PVP waveforms are recorded from which one average PVP waveform is
determined and analyzed. From the average PVP waveform, some characteristic points
(parameters) are identified that are directly related to arterial compliance (stiffness) and wave
reflections. With these parameters and previously measured peripheral (regular) blood
pressure the central systolic blood pressure value and the central pulse pressure value are
then determined

The time that is needed to determine the central blood pressure value may vary among
patients; i.e. with faster heart rate, less time is required for collecting the number of required
PVP waveforms. It is very important to keep the arm still during the time the PVP waveforms
are collected.

Accuracy of the central blood pressure parameters

The accuracy of central blood pressure parameters performed with this device can only reliably
be determined against intra-arterial blood pressure measurement. The device is a certified
equivalence with the WatchBP Office Central that has been validated against simultaneous
recorded intra-arterial blood pressure measurement in 85 subjects and showed high
accuracy





MAP (Mean Arterial Pressure)

The device measures the true mean arterial pressure (MAP) of the patient. Each measurement
includes a single MAP value. The MAP value will always be displayed together with the systolic
and diastolic blood pressure value.
