Before Measurement - ETEKCITY B22 User Manual

Before Measurement

• If the monitor is being used by multiple people, wash
hands before each measurement.
• Sit on a chair with your feet flat on the floor and your
arms on the table so the cuff is level with your heart.
[Figure 1.1]
• Remove any clothing that fits closely to your upper
arm.
• Sit for at least 5 minutes in a comfortable, secure
environment before measurement.
• Your blood pressure should be measured sitting down.
Take note if your blood pressure is taken in a different
position.
• Take measurements on both arms the first time you
use the monitor to make sure it is calibrated and both
readings are similar.
• Take measurements on the same arm (normally left).
• Avoid any electromagnetic interference when taking
measurements.
• Avoid flexing arm muscles or trying to support your
arm, as this can increase blood pressure. Use a cushion
for support if necessary.
• If the arm artery lies considerably lower or higher than
the heart, the measurement may be incorrect. Each
25–30 cm difference in height between your heart and
the cuff results in a measurement error of 10 mmHg.
• Only use the included cuff.
• A loose or improperly fitted cuff will result in incorrect
measurements.
