Using The Monitor Selecting the Correct Cuff Size

Using the correct cuff size is important for an accurate reading. If the cuff is not the proper size, the reading may yield an incorrect blood pressure value. The arm size is printed on each cuff. The index and proper fit range, on the cuff, tell you if you are applying the correct cuff. (Refer to "Applying The Arm Cuff" on the next page. ) If the index points outside of the range, contact your local dealer to purchase a replacement cuff. The arm cuff is a consumable. If it becomes worn, purchase a new one.

How To Take Proper Measurements For the most accurate blood pressure measurement: Sit comfortably on a chair. Rest your arm on the table. Do not cross your legs. Keep your feet on the floor and straighten your back. Relax before measurement. Place the center of the cuff at the same height as your heart. Remain still and keep quiet during measurement. Do not measure immediately after physical exercise or a bath. Rest before taking the measurement. Try to measure your blood pressure at the same time every day.

Measurement During measurement, it is normal for the cuff to feel very tight. (Do not be alarmed).

After Measurement After measurement, press the START button to turn off the power. Remove the cuff. Note: The device has an automatic power shut-off function, which turns the power off automatically one minute after measurement. Allow at least three minutes between measurements on the same person.

Release the button at the desired systolic pressure

Sit down in a comfortable position. Place Refer to the previous page the arm to be used for the measurement on a table or other support so that the for measurement center of the cuff will be at the same height as your heart. Relax for about five or 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 the pulse reading will usually be faster than normal. An individual's blood pressure varies constantly, depending on what you are doing and what you 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. Refer to page 4 for the description of the symbols. This blood pressure monitor is intended for use by adults only. Consult with your physician before using this device on a child. A child should not use this device unattended. English

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 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 under a doctor’s supervision. 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? Blood pressure measured at a clinic or doctor's office 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 influences on blood pressure readings, supplements the doctor's readings and provides a more accurate, complete blood pressure history.

WHO Blood Pressure Classification Diastolic blood pressure

Standards to assess high Reference Material: Journal of Hypertension 1999, Vol 17 No.2 blood pressure, without Grade 3 hypertension (severe) regard to age, have been Grade 2 hypertension (moderate) established by the World Health Organization (WHO), Grade 1 hypertension (mid) as shown in the chart. High-normal Normal Blood Pressure Variations Optimal An individual’s blood pressure varies greatly on a daily and Systolic blood pressure 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 English
