Notes For Accurate Measurement
Sit down in a comfortable position. Place your arm on a table or other support. Raise your hand so that the cuff isat the same level as your heart.
Relax for about five to ten minutes before taking a measurement. If you are excited or depressed by emotional
stress, the measurement will reflect this stress as a higher (or lower) than normal blood pressure reading and thepulse reading will usually be faster than normal.
An individual's blood pressure varies constantly, depending on what they are doing and what they have eaten.
What you drink can have a very strong and rapid effect on your blood pressure.
This device bases its measurements on the heartbeat. If you have a very weak or irregular heartbeat, the device
may have difficulty determining your blood pressure.
Should the device detect a condition that is abnormal, it will stop the measurement and display an error symbol.
See page 5 for the description of symbols.
This blood pressure monitor is intended for use by adults only. Consult with your physician before using thisdevice on a child. A child should not use this device unattended.

About Blood Pressure
What is Blood Pressure?
Blood pressure is the force exerted by blood against the walls of the arteries. Systolic pressure occurs when theheart contracts. Diastolic pressure occurs when the heart expands. Blood pressure is measured in millimeters of
mercury (mmHg). One's natural blood pressure is represented by the fundamental pressure, which is measured
first thing in the morning while one is still at rest and before eating.

What is Hypertension and How is it Controlled?
Hypertension, an abnormally high arterial blood pressure, if left unattended can cause many health problems including
stroke and heart attack. Hypertension can be controlled by altering lifestyle, avoiding stress, and with medication undera doctor’s supervision.
English 14

To prevent hypertension or keep it under control:
Do not smoke
Exercise regularly
Reduce salt and fat intake
Have regular physical checkups
Maintain proper weight

Why Measure Blood Pressure at Home?

WHO Blood Pressure Classification

Standards to assess high blood pressure, without regard to age,have been established by the World Health Organization (WHO),as shown in the chart at the right.

Diastolic blood pressure

Blood pressure measured at a clinic or doctor's office may cause
apprehension and can produce an elevated reading, 25 to 30 Reference Material: Journal of Hypertension 1999, Vol 17 No.2

Grade 2 hypertension (moderate)
readings, supplements the doctor's readings and provides a moreaccurate, complete blood pressure history.
Grade 1 hypertension (mid)High-normal
NormalOptimalSystolic blood pressure

An individual’s blood pressure varies greatly on a daily and seasonal basis. It mayvary by 30 to 50 mmHg due to various conditions during the day. In hypertensive
individuals variations are even more pronounced. Normally, the blood pressure rises
while at work or play and falls to its lowest levels during sleep. So, do not be overly
concerned by the results of one measurement.
Take measurements at the same time every day using the procedure describedin this manual to get to know your normal blood pressure. Regular readings givea more comprehensive blood pressure history. Be sure to note the date andtime when recording your blood pressure. Consult your doctor to interpret yourblood pressure data.
