Indications for Use
The Microlife Upper Arm Automatic Digital Blood Pressure and Cardiovascular
Screening Monitor Model WatchBP Ofice Vascular (TWIN200 VSR) 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) for or use in adults and pediatrics (but not neonates) with arm cuff
circumference sizes ranging from 14 -52 cm.
The device screens for the presence of atrial ibrillation during measurement.
The device can accurately measure blood pressure in pregnant patients including those
with known or suspected pre-eclampsia.
A recommended test for diagnosing Peripheral Artery Disease (PAD) is performing ankle-
arm measurements to assess the ankle brachial index (ABI). The device has proven to be
a fast, easy, and reliable alternative for Peripheral Arterial Disease (PAD) screening as has
been clinically validated with a Doppler device [1].
The device also provides a user-friendly and more reproducible cuff-based brachial-
ankle PWV measurement method to evaluate arterial stiffness in clinical practice.
The device provides aortic blood pressure parameters, includes central systolic blood
pressure (cSBP), central pulse pressure (cPP) and central diastolic blood pressure
(cDBP), non-invasively through the use of a brachial cuff. This was validated against
invasive blood pressure measurement and showed that the device determines central
blood pressure measurement with high accuracy [2].
The memory data can be transferred to the PC (personal computer) running the
WatchBP Analyzer software by connecting the monitor via USB cable or Bluetooth.
The device is meant for useing by healthcare professionals in clinical practice.
Contra-indications
The device is not intended for measuring blood pressure in patients of age less than 3
years old ( infant or neonates).
The device measures brachial blood pressure using pressured cuff over upper arm. If
the measurementing arm or leg suffers from injuries (e.g. open wounds) or conditions
(e.g. intravenous drip) or has stents implanted making it unsuitable for surface contact or
pressurization of the arm, do not use the device.
The device is not intended to measure pulse rate to check the frequency of pacemaker.
