Blood Pressure Measurement; Working Environment; Measurement Requirements - Huawei MLY-B10 Quick Start Manual

2. Blood Pressure Measurement

2.1 Principles
This device measures blood pressure by using the oscillometric method. As the strap (airbag) pressure
increases, the device extracts and analyzes the signals of pressure oscillations in the airbag using the
pressure sensor, and automatically calculates the high pressure (systolic pressure), low pressure (diastolic
pressure), and pulse rate.

2.2 Working Environment

Network Environment
Temperature
Humidity
Atmospheric pressure
Caution
• Keep the device away from electromagnetic interference, vibration, and noise.
• Failure to comply with the working environment requirements specified in this guide will cause the prod-
uct to fail to reach the claimed performance specifications or damage the parts.

2.3 Measurement Requirements

Any blood pressure measurement data may be influenced by the location of the measurement, posture
(standing, sitting, or lying down), movement, or physiological conditions.
To ensure the accuracy of the measurements, observe the following requirements:
• Rest for 5 minutes before a measurement and keep your body naturally relaxed until the measurement is
complete. Do not perform the measurement when you feel emotional or stressed.
• Perform a measurement in a quiet environment. Do not speak, bend your fingers, or move your body or
arms during the measurement.
• Rest your wrist for 1 to 2 minutes or longer before you perform the next measurement. During this period
of time your arteries will return to how they were before the blood pressure was measured.
• Avoid eating, drinking alcohol, smoking, and exercising for at least 30 minutes before taking a measure-
ment.
