Using the Monitor
Applying the Cuff
1. Wrap the cuff around your wrist about 1 cm above your hand as shown in
the gure at the right.
2. Apply the cuff tightly using the Velcro strip.
Note: For accurate measurements, apply the cuff tightly and measure on a bare wrist
How to Take Accurate Measurements
• Remain still and keep quiet during measurement.
• Sit down in a comfortable position. Place your elbow on a table with your palm facing upward and the
cuff is at the same level as your heart.
• Relax for about ve to ten minutes before measurement. If you are excited or depressed by emotional
stress, the measurement will reect this stress as a higher (or lower) than normal blood pressure
reading and the pulse reading will usually be faster than normal.
• Try to measure your blood pressure at about the same time every day.
• An individual’s blood pressure varies constantly, depending on what they are doing, what they have
eaten and what they drink can have a very strong and rapid effect on your blood pressure.
• Do not measure immediately after physical exercise or a bath. Rest for twenty or thirty minutes before
taking the measurement.
• Do not cross your legs. Keep your feet at on the oor and straighten your back.
• This device bases its measurements on the heartbeat. If you have a very weak or irregular heartbeat,
the device may have difculty determining your blood pressure.

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 the heart 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 rst 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 under a doctor’s supervision. To prevent hypertension or keep it under control:
Why Measure Blood Pressure at Home?
Blood pressure measured at a clinic or doctor’s ofce may cause apprehension and can produce an
elevated reading, 25 to 30 mmHg higher than that measured at home. Home measurement reduces the
effects of outside inuences on blood pressure readings, supplements the doctor’s readings and provides
a more accurate, complete blood pressure history.
• Do not smoke
• Reduce salt and fat intake
• Maintain proper weight
• Exercise regularly
• Have regular physical checkups

E-18
Blood Pressure Variations
An individual’s blood pressure varies greatly on a daily and
seasonal basis. It may vary 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 described in this manual to get to know your normal
blood pressure. Regular readings give a more comprehensive
blood pressure history. Be sure to note the date and time when
recording your blood pressure. Consult your doctor to interpret
your blood pressure data.
