How to Take Accurate 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 flat on the floor and straighten your back.
• Relax for about five to ten minutes before measurement.
• Place the center of the cuff at the same level as your heart.
• Remain still and keep quiet during measurement.
• Do not measure right after physical exercise or a bath. Rest for twenty or thirty minutes 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 the device off.
Remove the cuff and record your data.

Note: The device has an automatic power shut-off function, which turns the device off approximately one minute after measurement.
Allow at least three minutes between measurements on the same person.

Measurements

Before measurement, refer to “Notes for Accurate Measurement” on the next page.

Normal Measurement

1. Place the cuff on the arm (preferably the left arm). Sit quietly during measurement.
2. Press the START button.
All of the display segments are displayed.
Zero (0) is displayed blinking briefly.
The display changes, as indicated in the figure at the right, as the measurement begins.
The cuff starts to inflate. It is normal for the cuff to feel very tight. A pressure bar indicator is displayed, on the left edge of the display,  during inflation.
Note: If you wish to stop inflation at any time, press the START button again.
3. When inflation is complete, deflation starts automatically and (heart mark) blinks, indicating that the measurement is in progress. Once the pulse is detected, the mark blinks with each pulse beat.
Note: If an appropriate pressure is not obtained, the device starts to inflate again automatically.
To avoid re-inflation, refer to “Measurement with the Desired Systolic Pressure” on the next page.
4. When the measurement is complete, the systolic and diastolic pressure readings and pulse rate are displayed.
The cuff exhausts the remaining air and deflates completely.
5. Press the START button to turn the device off.
Note: Allow at least three minutes between measurements on the same person.|
---|---

Measurement with the Desired Systolic Pressure
The UA-767S is designed to detect the pulse and inflate the cuff to a systolic pressure level automatically.
Use this method when re-inflation occurs repeatedly or when the results are not displayed even if the pressure decreases to 20 mmHg or less.

1. Place the cuff on the arm at heart level (preferably the left arm).
2. Press the START button.
3. When the zero blinks, press and hold the START button until a number about 30 to 40 mmHg higher than your expected systolic pressure appears.
4. When the desired number is reached, release the START button to start measurement. Continue to measure your blood pressure as described on the previous page.|
---|---

Notes for Accurate Measurement

• Sit down in a comfortable position. Place your arm on a table with your palm facing upward and the cuff at 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 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 7 for the description of symbols.
• This blood pressure monitor is intended for use by adults. Consult with your physician before using this device on a child. A child should not use this device unattended.
• The automatic blood pressure monitor’s performance may be affected by excessive temperature or humidity, or altitude.

Recalling the Memory Data

Note: This device stores the last 60 measurements in memory.

1. When nothing is displayed, press and hold the START button to recall the stored data
2. Release the button when displaying the average data.
3. The data number and stored data are automatically displayed in order from the last measurement.
4. The display will turn off automatically after all data are displayed.

Note: If you press the START button while recalling data, the device turns off.

What Is The IHB/AFib Indicator?

When the monitor detects an irregular rhythm during the measurements, the IHB/AFib indicator will appear on the display with the measurement values.

Note: We recommend contacting your physician if you see this IHB/AFib indicator frequently.

What Is The AFib?

The heart contracts due to electrical signals occurring in the heart and sending blood through the body. Atrial fibrillation (AFib) occurs when the electrical signal in the atrium becomes confused and leads to disturbances in the pulse interval. AFib can cause blood to stagnate in the heart, which can easily create clots of blood, a cause stroke and heart attack.

％IHB/AFib

%IHB/AFib is displayed as the frequency of IHB/AFib detected.
IHB/AFib can detect not only noises such as physical movement but also an irregular heartbeat. Therefore, we recommend contacting your physician if %IHB/AFib level is high.

Display of %IHB/AFib: %IHB/AFib is displayed when displaying average values.
(Refer to “2. Recalling the Data” in “Operation Mode”) %IHB/AFib is not displayed when the memory number is six or less.
Average value display

Pressure Bar Indicator

The indicator monitors the progress of pressure during measurement.

WHO Classification Indicator

Each segment of the bar indicator corresponds to the WHO blood pressure classification described on the next page.

• : The indicator displays a segment, based on the current data, corresponding to the WHO classification.

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
• Reduce salt and fat intake
• Maintain proper weight
• Exercise regularly
• Have regular physical checkups

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

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.
