Preface

The WatchBP Ofce Central has been validated against simultaneous recorded intra-arterial blood pressure measurement, which is the gold standard for

validation of central blood pressure measurement, and showed extreme high accuracy1. The WatchBP central has passed the validation protocol of the BHS

for accuracy in blood pressure measurement (A/A) and is equipped with innovative screening tools such as:

• An implemented atrial brillation (Ab) detection system that has proven excellent accuracy

2, 3

and is ofcially recommendation by the National Institute of

Clinical health and Excellence (NICE) in the UK 4.

• Two arm cuffs that allow simultaneous blood pressure measurement of both arms for accurate determination of inter-arm blood pressure differences

5, 6

This mode is highly supported by the latest ESH guidelines (2013) stating that Inter-arm difference in blood pressure is only meaningful when obtained from

simultaneous arm blood pressure measurement 7.

• Ankle-brachial index (ABI) performance that is validated against Doppler for accuracy with positive results and additionally showed that the assessment led

to a signicant time reduction as compared to Doppler

. Finally, the automated calculation of the ABI value guarantees uniformity and prevents errors due to

registration and calculation failures 9.

Selecting the correct cuff

Two upper arm cuffs and an ankle cuff are provided within the standard package of the WatchBP Ofce Central.

Fitting the cuff properly

1) Place the cuff over the left (or right) upper arm so that the air tube and artery mark arrow point towards the lower arm.

Special Functions

Central blood pressure

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.

How is central blood pressure measured?

The WatchBP Ofce Central uses brachial pulse volume plethysmography (PVP) waveforms

to determine central

blood pressure. The WatchBP Ofce Central is designed to perform PVP at a cuff pressure of 60 mmHg. Based on the analysis of PVP waveforms the central systolic blood pressure (CBP) value and the central pulse pressure value (CPP) are determined 1.

Accuracy of the WatchBP Ofce Central

The accuracy of central blood pressure measurement performed with an automated oscillometric device can only reliably be determined against intra-arterial blood pressure measurement. The WatchBP Ofce Central has been validated

against simultaneous recorded intra-arterial blood pressure

measurement in 85 subjects and showed high accuracy

Central Pulse Pressure (CPP)

Central Pulse Pressure by this monitor is estimated directly through pulse volume plethysmography (PVP) waveform analysis.

volume plethysmography with a noninvasive blood pressure monitor. Am J

Hypertens, 2012. 25: 542-8.

2. Cheng, H.M., et al., Measurement accuracy of a stand-alone oscillometric

central blood pressure monitor: a validation report for Microlife WatchBP Ofce

Central. Am J Hypertens, 2013. 26: 42-50.

Page 22

Mean Arterial Pressure (MAP)

The WatchBP Ofce Central device measures the true mean arterial pressure (MAP). Each measurement includes a single MAP value. The average measurement will display the average MAP value. When viewing in Memory mode, the MAP value will be displayed with the systolic and diastolic pressure once every 5 seconds.

Pulse Pressure (PP)

This measurement device provides the pulse pressure (PP) of the patient: pulse pressure = systolic - diastolic pressure.

Each measurement includes the calculation of a single PP

value. The average measurement will display the average PP value. When viewing in Memory mode, the PP value will be displayed with the systolic/diastolic pressure once every

5 seconds.

The Mean Arterial Pressure (MAP) in this device is determined from the

maximum peak of the oscillometric envelope curve.

Appearance of the atrial brillation (Ab) indicator for early detection

The WatchBP Ofce Central is designed to screen for asymptomatic atrial brillation during blood pressure

measurements in «SCREEN» mode. If two out of three measurements in «SCREEN» mode detect atrial brillation, the

Ab icon is displayed. This device is able to detect atrial brillation with high accuracy: a sensitivity of 97% and a specicity of 89%.

This device detects atrial brillation, a major cause of stroke.

Not all risk factors for stroke, including atrial utter, may be detected by this device.

This device may not detect atrial brillation in people with

pacemakers or debrillators.

Ab Detector

The device can screen for atrial brillation during blood

pressure measurement.

Occasionally, the device might falsely detect atrial brillation which can have two causes:

1) The arm has moved during blood pressure

measurement. For this reason it is of essential importance to keep the arm still during the measurement.

2) Some arrhythmia (irregular heart beat) other than atrial brillation might be present. In such case it may still be useful to pay a visit to the doctor.

Page 24

About atrial brillation

Atrial brillation is a common heart rhythm problem.

It affects more than 2 million people in North America.

It is more common in older age and it is found in 18% individuals aged 85 years and older. It is a common cause of major strokes. About 15% of all strokes are caused by atrial brillation.

The elderly, or those with high blood pressure, diabetes or heart disease are more likely to get a stroke if they have atrial brillation.

Atrial brillation is a rhythm problem that can last from a few minutes, to days or weeks and even years. Atrial brillation

can cause blood clots in the upper chambers of the heart

(the atria). These clots can break off and ow to the brain

causing a stroke.

With the right treatment the chance of stroke can be

reduced by two-thirds.

Special Function (cont.)

Determine the proper arm and inter-arm difference

If the blood pressure difference between two arms is more than 20mmHg for Systolic or 10mmHg for Diastolic at all three measurements, the device indicates the arm with the higher blood pressure value by displaying L or R and the “IAD” icon. The “IAD” icon and readings of the higher arm ash to indicate

that more attention is needed as this patient might have peripheral arterial disease.

WatchBP Ofce Central

ABI (Ankle Brachial Index)

The systolic blood pressure values of a person’s arm and leg need to be measured In order to determine ABI (Ankle Brachial Index).

The ankle-brachial index (ABI) is then calculated using the quotient of the systolic pressure value from the leg measurement and the systolic pressure value from the arm

measurement.

A low ankle-brachial index (ABI) is indicative of systemic vascular disease, and places a patient in the high-risk category.
