Microlife WatchBP Office Central Instruction Manual page 2

Preface
The WatchBP Office 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 accuracy in measuring central systolic,
central diastolic and central pulse pressure
pressure measurement (A/A) and is equipped with other innovative screening tools such as:
• An implemented atrial fibrillation (Afib) detection system that has proven excellent accuracy
the National Institute of Clinical health and Excellence (NICE) in the UK
• Two arm cuffs that allow simultaneous blood pressure measurement of both arms for accurate determination of inter-arm BP
differences . This mode is highly supported by the latest ESH guidelines (2013) stating that Inter-arm difference in blood pressure is
5, 6
only meaningful when obtained from simultaneous arm blood pressure measurement
• Ankle-brachial index (ABI) performance that is validated against Doppler for accuracy with positive results and additionally showed
that the assessment led to a significant time reduction as compared to Doppler
guarantees uniformity and prevents errors due to registration and calculation failures
