Systolic and diastolic pressure
The heart consists of two large chambers - the
ventricles - and two smaller chambers - the atria.
The ventricles collect blood from the atria and
expel it towards the peripheral beds of blood
vessels within the body and the lungs. The atria
collect blood from these peripheral beds and
prime the ventricles.
When the ventricles contract and pump blood out
of the heart, the blood pressure reaches its
maximum value in the cycle, which is called
systolic pressure (Fig. 3).
When the ventricles relax and are filled again with
blood, the blood pressure reaches its minimum
value in the cycle, which is called diastolic pressure
(Fig. 4).
Blood pressure classification
Consult a physician in case of questions about
your blood pressure. Your physician can inform
you:
- About your normal blood pressure range.
- If your measuring result falls out of the range.
- Whether your blood pressure has reached a
dangerous level.
The following table shows the classification system
for the blood pressure measurements used in this
device. This system follows the classification
system of the World Health Organisation (WHO).

Irregular heart rate detector
The device is equipped with an irregular heart rate
detector. An irregular heart rate is detected when
the heart rhythm varies above a pre-defined level
while the device is measuring the systolic and
diastolic blood pressure. During each
measurement, this device records the heartbeat
intervals and calculates the standard deviation. If
the standard deviation exceeds a pre-defined
threshold, the irregular heart rate detector symbol
lights up when the measurement results are
displayed (Fig. 5).
Caution:The appearance of the irregular heart rate
detector symbol indicates that a heart rate
irregularity was detected during measurement.
Usually this is not a cause for concern. Due to the
irregularity in your heart rate the blood pressure
measurement might not be accurate, i.e. it might
not reflect the 'real' situation in your body.
However, if the symbol appears often, we
recommend that you seek medical advice. Please
note that the device does not replace a cardiac
examination.
Preparing for use
Pairing the blood pressure monitor to
your mobile device
Note: Before you use the device for the first time,
remove the protective foil from the display.
Note: To switch on the device for the first time,
press the 'on' button for 3 seconds.
The blood pressure monitor is equipped with
Bluetooth
®
Smart. You can receive your personal
health data on a mobile device that is equipped
with the Bluetooth
®
Smart function. Download the
Philips HealthSuite health app from the App store
or Google Play. Use the search term 'Philips
HealthSuite health app'. The app is available for
iOS
®
8.0+ and Android
TM
4.4+.
Note: You can only use the Philips HealthSuite
health app to communicate with the device. It is
not possible to use third party applications.
1
Download the Philips HealthSuite health app
on your mobile device, start the app and follow
the instructions to create a user profile and add
the blood pressure monitor device.
2 Make sure the app is active and Bluetooth is on
when pairing is in progress.
-
Keep the mobile device and the blood
pressure monitor within transmission range
(no more than 16 feet (5 meters) from each
other, in the same room).
3 With the device turned off, press the 'on' button
for 3 seconds, until it turns on in pairing mode.
-
These symbols are shown on the display
alternatively, indicating that the connection
is being established: (Fig. 6) and (Fig. 7).
4 When pairing is successful, the display shows
this symbol: (Fig. 8). The app shows which user
profile is assigned to you.
-
If the connection fails, the display shows this
symbol: (Fig. 9).
