De nitions and Classi cations of Blood Pressure Levels
12. Intended Use
• This device is noninvasive blood pressure monitor by
oscillometric method. This device can measure the systolic
blood pressure (SYS), the diastolic blood pressure (DIA) and the
pulse rate automatically.
• This device is intended to be used for checking personal health
condition at home under the direction of a physician and is not
intended to be a diagnostic device.
• This device is not intended for use with neonates or infant, and
not intended for automatic cycling measurement.
Measure your blood pressure at the same time each day.
* Your blood pressure changes all the time. This means that data
gathered over a long period has far more signi cance than data
from just one measurement. For this reason, you must measure your
blood pressure on a daily basis. Ideally, you should measure your
blood pressure at the same time each day, wherever possible.
