L-XL
Each cuff is provided with 130 cm air tube.
*
Use only cuffs provided by Microlife!
*
Contact Microlife or its authorized distributor to purchase cuffs.
*
M and L size cuffs are included as standard accessories.
*
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 properly, 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. Use a different size cuff if the range index
at the end of the cuff does not fall into the range
specified by the range stripes.

Hide Cuff Pressure during deflation
– This option helps you to determine Korotkoff
K1 and K5 sound readings without digit
preference. To use the HIDE function in
MANUAL mode, push button to select
the setting of HIDE function and confirm the
selection by button and finish the setting
of MANUAL mode.
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 are determined by the physician using 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 deation and nish the measurement of
MANUAL mode and show the pressure you have marked. Alternatively, the device
quickly deates and shows the pressures after having pushed the button 4 times, or the
cuff pressure has reached 20mmHg during the deation 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 during deflation to release the pressure in
the cuff faster, at around 8 -12 mmHg/second.
The recommended deflation rate for auscultation is 2-3 mmHg per second. Do not assess K1 or K5 sound while
*
holding the button.
If HIDE in MANUAL mode is selected, the cuff pressure during deflation will not be displayed. The display shows "---"
*
during cuff deflation.

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
14
1
.
Page 13
WatchBP Office
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
Sung, S.H., et al., Measurement of central systolic blood pressure by pulse volume plethysmography with a
noninvasive blood pressure monitor. Am J Hypertens, 2012. 25: 542-8.
Cheng, H.M., et al., Measurement accuracy of a stand-alone oscillometric central blood pressure monitor: a
validation report for Microlife WatchBP Office Central. Am J Hypertens, 2013. 26: 42-50.
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.
