1. What is blood pressure?
Blood pressure is the force of the blood pushing against the walls of the arteries each time the heart beats. Your heart acts like a pump, sending blood surging through your blood vessels each time it contracts. High blood pressure occurs when blood vessels become narrow or stiff. As the arteries get stiffer, they tend to resist the force of heart contractions. To ensure that enough blood flows through the arteries to the organs, blood pressure increases.

When you take your blood pressure, both your systolic and diastolic pressures are measured. Systolic pressure is the pressure exerted when the heart contracts and pumps blood into the arteries. Diastolic pressure is the pressure exerted when the heart expands, or relaxes. If your blood pressure measurement is 120 over 80 (120/80), for example, your systolic pressure is 120 while your diastolic pressure is 80.

High blood pressure, or hypertension, is a condition that affects 40 million Americans, and is the leading cause of stroke and a major cause of heart attack. Because there are no clear warning signs or symptoms, it is important that you check your blood pressure regularly.

2. What is the Panasonic Precise Logic® Measurement System?
Most blood pressure measuring systems measure only the strength of the blood flow (pulse wave). However, because blood flow varies according to the conditions of the blood vessels and the structure of the arm, measuring blood pressure by conventional methods can be difficult.

The Precise Logic® Measurement System verifies two checks - the strength and shape of the pulse wave created by your blood flow. This double check system provides more accurate and consistent blood pressure measurements than the more conventional measurement methods.

3. Why should I measure my blood pressure?
Measuring your own blood pressure is an important way of monitoring your health. High blood pressure (hypertension) is a major health problem, which can be treated effectively once detected. Measuring your blood pressure between doctor visits on a regular basis in the comfort of your home, and keeping a record of the measurements, will help you to monitor any significant changes in your blood pressure. You should also keep an accurate record of your blood pressure, to help your doctor diagnose and possibly prevent any health problems in the future.

4. When should I take my blood pressure measurements?
Try to take your blood pressure measurements at the same time and under the same conditions every day. The ideal time to measure your blood pressure is in the morning just after waking up, before breakfast and before any major activity or exercise. This will give you a base blood pressure measurement. You should relax for about 5 minutes before taking the measurement.

5. What do the blood pressure measurements mean?
Please see the chart of World Health Organizations guidelines for blood pressure measurements (below). However, this is just a guide, and your measurements should only be interpreted by a health professional who is familiar with your medical history.

World Health Organization (WHO) Guidelines for Blood Pressure Readings
Blood Pressure Categories
(excludes people who are on high blood pressure medication or experiencing serious illness)
Category Systolic Blood Pressure Diastolic Blood Pressure
Normal Less than 130 Less than 85
Normal High 130-139 85-89
Low Hypertensive 140-459 90-99
Moderate Hypertensive 160-179 100-109
Severe Hypertensive Greater than 180 Greater than 110

If your systolic pressure falls in one category but your diastolic is in another, your level is classified in the higher of the two categories.

6. If I use the Panasonic Blood Pressure Monitor, do I still have to go to my physician?
Yes. Just because you're monitoring your blood pressure, does not mean that you can diagnose what the measurements actually mean. Blood pressure measurements need to be interpreted by a health professional who is familiar with your medical history.

7. Can I use the Panasonic Blood Pressure Monitor if I am on heart medication?
If you are taking heart medication, consult with your physician to determine the most appropriate time to measure your blood pressure. Never change a prescribed medication without first consulting with your physician.

8. Can I use this product if I have irregular circulation?
Yes. For persons with irregular or unstable circulation resulting from diabetes, liver disease, arteriosclerosis or other medical conditions, there may be variations in blood pressure values measured at the wrist versus at the upper arm. Monitoring the trends in your blood pressure taken at either the arm or the wrist is nevertheless useful and important.

9. I noticed my blood pressure measurements are sometimes different? Why?
Blood pressure can vary based on many factors, including age, gender, weight and physical condition. In general, a person's blood pressure is lower during sleep and higher when he or she is active. Blood pressure can change easily in response to physiological changes.

The environment in which your blood pressure is measured can also affect the results. Having your blood pressure measured by a healthcare professional in a hospital or clinic can cause nervousness and may result in a temporarily elevated reading. It is not unusual to have a lower blood pressure reading at home. Because blood pressure measurements taken in a clinical setting can vary considerably from those taken at home, blood pressure should be measured not only occasionally in the doctor's office, but also on a regular basis at home.

To accurately compare your measurements at home with your physician's reading, take your Panasonic blood pressure monitor to your doctor's office and compare readings in this setting.

10. Why do I get different measurements each day?
The following situations may cause substantial variations in blood pressure readings and should therefore be avoided at least 30 minutes prior to taking your blood pressure.

Blood pressure will be higher than usual:

  • when you are excited or tense
  • while you are taking a bath
  • during exercise or soon after exercising
  • when it is cold
  • within one hour after eating
  • after drinking coffee, tea or other beverages containing caffeine
  • after smoking tobacco
  • when your bladder is full
Blood pressure will be lower than usual:
  • after taking a bath
  • after drinking alcohol

11. How do I measure my blood pressure?
Wrap the monitor around your arm or wrist and pump air into the monitor to stop the flow of blood through a main artery. Slowly let the air out of the monitor to release blood through the blood vessel so that a measurement can be taken.

Two numbers will appear on the monitor. The first number measures the systolic pressure — the pressure in the arteries when the heart beats and fills them with blood. The second number indicates the diastolic pressure — the pressure in the arteries between heartbeats.

Normal blood pressure levels range from 120/80 to 139/89 (systolic over diastolic).* If you record a high reading on more than two occasions, please contact your physician.

  • Taking measurements while sitting down
    Place your elbow on a table. Using a flat object as support, position your wrist at heart level. Your blood pressure measurement will be too low if you hold your hand too high, or too high if you hold your hand too low. Open and relax your hand with the palm facing up (closing your hand will cause inaccurate readings). Do not bend your wrist inward, as bending your wrist will cause inaccurate readings. If possible, empty your bladder before measuring your blood pressure, for a more accurate reading.

    To begin measurement, press the Start (On/Off) button.
    To switch the unit off, press the Start (On/Off) button.

  • Taking measurements while lying down
    Lie on your back. Rest your wrist on a support or cushion with the palm side facing up, position your wrist at heart level. Open and relax your hand with the palm facing up (closing your hand will cause inaccurate readings). Do not bend your wrist inward, as bending your wrist will cause inaccurate readings. If possible, empty your bladder before measuring your blood pressure, for a more accurate reading.

    To begin measurement, press the Start (On/Off) button.
    To switch the unit off, press the Start (On/Off) button.

12. How do I set the time and date? (EW284)
After inserting the batteries, follow the steps below to set the time and date so that your blood pressure measurements will be store according to the correct time and date.

  • Press the time mode and the time setting buttons with a ballpoint pen or other blunt-tipped object like a paper clip.
  • When you press the time mode button repeatedly, the figures will blink in the following order: month (mon) day (d) hour minute.
  • Adjust the figure that is blinking by pressing the time setting button until the correct digit appears, then press the time mode button to set it.
  • Pressing the time setting button once will cause the display to advance by one digit; keeping it pressed will cause it to advance continuously.
  • After you have adjusted the minutes setting, press the time mode button to save the settings.

13. How do I store a measurement in memory? (EW284)
To store a measurement, press the Memory button. Up to 60 measurements can be stored and recalled later. After you have stored 60 measurements, the oldest ones will be deleted automatically as you add new ones. The present measurement (Systolic/Diastolic/Pulse) will be stored together with the date and time.

14. How can I view my stored measurements? (EW284)
To view a stored measurement, press the Recall button. The most recently stored data (Systolic/Diastolic/Pulse) will be displayed. By pressing the Recall button repeatedly, you can browse through all the stored data (sequence 60-1).

If no data is entered for 30 seconds, the display will return to the time and date display. In the date and time display, the recalled data number will be briefly displayed and then the date and time when the recalled value was measured will be displayed.

Press the Start (On/Off) button to finish.
