Introduction

Intended Use

The FORA ACTIVE Series Multi-mode Blood Pressure Monitoring System is intended to be used to measure the systolic and diastolic blood pressure and pulse rate by using a non-invasive technique in which an inflatable cuff is wrapped on the upper arm. Do not use this system on babies, young children or persons who cannot express their consent.

Test Principle

Blood pressure is measured non-invasively at the arm based on oscillometer method. For people of common arrhythmia, such as atrial or ventricular premature beats or atrial fibrillation we recommend to use auscultatory mode. The reading obtained by single and average mode which use oscillometer method is for reference only and should be discussed with the healthcare professionals.

Getting Started

Testing Your Blood Pressure

Before Measurement
  • Avoid caffeine, tea, alcohol and tobacco for at least 30 minutes before measurement.
  • Wait 30 minutes after exercising or bathing before measurement.
  • Sit or lie down for at least 10 minutes before measurement.
  • Do not measure when feeling anxious or tense.
  • Take a 5-10 minute break between measurements. This break can be longer if necessary, depending on your physical conditions.
  • Keep the records for your doctor as reference.
  • Blood pressure varies between each arm. Always measure your blood pressure on the same arm.
Fitting the Cuff
  1. Connect the air plug of the tubing to the air jack of the device.

  2. Assemble the cuff.
    The smooth surface should be inside the cuff loop and the metal D-ring should not touch your skin.
    Fitting the Cuff 01 Note: Before using the cuff, be sure the cuff size fits with your upper arm circumference.

  3. Stretch your left (right) arm in front of you with your palm facing up. Slide and place the cuff onto your arm with the air tube and artery mark region (in red) toward the lower arm.
    Wrap and tighten the cuff above your elbow. The red line on the edge of the cuff should be approximately 0.8 to 1.2 inches (2 to 3 cm) above your elbow. Align the tube over the main arteries on the inside.
    Fitting the Cuff 02

  4. Leave a little free space between the arm and the cuff. You should be able to fit 2 fingers between them.

  5. Press the hook material firmly against the pile material. The top and bottom edges of the cuff should be tightened evenly around your upper arm.

Proper Measurement Position
  1. Sit down for at least 10 minutes before measuring.
  2. Place your elbow on a flat surface. Relax your hand with the palm facing up.
  3. Make sure the cuff is about the same height as the location of your heart.

Important!
If the cuff is relatively lower (higher) than the heart, the obtained blood pressure value could be higher (lower) than the actual value. A 15 cm difference in height may result in an error around 10 mmHg.

  1. Press POWER button. The device will turn on and the cuff will begin to inflate automatically. Remain still and do not talk or move during the measurement.
Measuring Blood Pressure

This device provides you different ways to measure your blood pressure.
When the device detects an irregular heart beat, the IRB symbol. If the problem still persists, please consult your doctor.
Important!
Always apply the pressure cuff before turning on the device.

  • A. Single Measurement
    Perform an individual blood pressure measurement.
1. Press POWER button All the LCD symbols will appear. Then the cuff will begin to inflate automatically.
2. The heart symbol will flash when a pulse is detected during the inflation. After the measurement, the monitor displays the systolic pressure, diastolic pressure and pulse rate.

Single Measurement

3. Press POWER button to turn the device off.

Note: If the device is idle for 3 minutes, it will turn off automatically.

  • B. Average Measurement
    Automatically performs three (3) consecutive blood pressure measurements and displays the average result in the end.
1. Press POWER button. The device will turn on and enter the averaging mode. Then the cuff will begin to inflate automatically.
2. After the first measurement is complete, the device will start counting down before the second measurement begins. The device will take three (3) measurements consecutively with an interval of 20 seconds.

Average Measurement 01 Note:
When the difference between the first and second systolic pressure is more than 15mmHg, the time interval for third measurement will be 40 seconds.

3. After taken three measurements, the results are averaged to produce the blood pressure measurement with AVERAGE symbol display on the screen. Press POWER button to turn the device off.  

Average Measurement 02

  • C. Auscultatory Mode
    Only well trained persons may use this mode to measure blood pressure manually. This manual method involves applying a stethoscope to the arm and listening to the pulse while the air is slowly let out from the cuff (the Korotkoff method). Please ask your health-care professional to train you how to use auscultatory mode.
    The systolic pressure is the maximum pressure in an artery at the moment when the heart is beating and pumping blood through the body. The diastolic pressure is the lowest pressure in an artery in the moments between beats when the heart is resting.
1. Place a stethoscope on the arm where there is a pulse. Wrap the cuff around the upper arm and hold in place with Velcro.
2. Press and hold POWER button until “AUS” symbol appears on the display with a beep. Release the button. Then cuff begins to inflate automatically.  

Auscultatory Mode 01

3. After reaching the cuff pressure, the deflation begins. You can adjust the inflation pressure by keep pressing to inflate if necessary. If you release , the inflation will stop and deflation begins.
4. The systolic pressure is measured when the operator first hears the pulse. Write down the value on the display. This value indicates the systolic pressure. You have to record the values as the result will not be stored in the memory.
5. The diastolic pressure is measured from the moment the operator is unable to hear the sound of the pulse. Write down the value on the display. This value indicates the patient’s diastolic pressure. You have to record the values as the result will not be stored in the memory.
6. The device will return to 0 mmHg after the measurement is completed. To turn off the device, press and hold POWER button or it will switch off automatically after idle for 3 minutes.  

Auscultatory Mode 02

Reviewing Test Results

Your device stores the 200 (P30 Plus BT only) most recent blood pressure test results along with respective dates and times in the memory. To recall the memory, start with the device off.
For P30 Plus
To review all test results, do the following:

  1. Press and release M. The “M” icon appears on the screen and the first reading you see is the last blood pressure result along with date and time.
    Reviewing Test Results 01

  2. Press M repeatedly to review other test results stored in the device.
    Reviewing Test Results 02

To review the day-average test results, do the following:

  1. Press and hold M for 3 seconds until the “Day Average” icon appears on the screen.

  2. Press M and the Day average result appears on the display.
    Reviewing Test Results 03

  3. Press M again to review the Day-time average result.
    Reviewing Test Results 04

  4. Press M again to review the Night-time average result.
    Reviewing Test Results 05

For P30 Plus and P30 Plus BT

Press M to review the average and general memory recall mode.
Note:

  • Day-time average is the average of the measurements taken during 4:00 A.M. to 11:59 A.M.
  • Night-time average is the average of the measurements taken during 6:00 P.M. to 11:59 P.M.
  • Press POWER button to exit the memory mode or leave it without any action for 3 minutes. The device will turn off automatically.
  • If using the device for the first time, the “—” icon appears when you recall the test results or review the average result. It indicates that there is no test result stored in the memory.

Classification of Blood Pressure

Human blood pressure naturally increases after reaching middle age. This symptom is a result of continuous ageing of the blood vessels. Further causes include diabetes, lack of exercise and cholesterol (LDL) adhering to the blood vessels. Rising blood pressure accelerates hardening of the arteries, and the body becomes more susceptible to apoplexy and coronary infarction.

This device does NOT serve as a cure for any symptoms or diseases.
The data measured is for reference only. Always consult your physician to have the results interpreted.
