Important Information Blood Pressure and Its Measurement

How Does High Blood Pressure Arise?

Blood pressure and heart rate are controlled by the lower portion of the brainstem called medulla oblongata. Blood pressure is dynamic and responds to respective situation by way of feedback mechanism via the nervous system. To adjust for blood pressure, the strength and frequency of the heart (pulse), as well as the width of circulatory blood vessels respond by changing. The latter is affected by way of fine muscles in the blood vessel walls. The level of arterial blood pressure changes periodically during the heart activity: During blood ejection (Systole), the value is maximal (systolic blood pressure value); at the end of the heart’s rest period (Diastole), the value is minimal (diastolic blood pressure value). For a healthy adult, the blood pressure values should lie within certain range (see below).

Blood Pressure Values Classification

According to American Heart Association (AHA) guidelines in 2017, blood pressure values are classified into 4 levels, as shown in the table below. Note: ESH/ESC guidelines may vary. Consult your healthcare provider for region-specific guidelines and information.

Further information

• If your blood pressure values are mostly in the normal range under resting conditions but exceptionally high under conditions of physical or psychological stress, it is possible that you are suffering from a medical condition called labile hypertension. Please consult your healthcare provider if you suspect this to be the case.
• Correctly measured diastolic blood pressure values of above 110mmHg will require immediate medical treatment.

There are measures you can take to prevent and/or reduce medically established high blood pressure.

Eating Habits

• Strive for a normal weight for your age and height.
• Avoid excessive consumption of table salt.
• Avoid fatty food.

Existing Illnesses

• Follow consistently any medical instructions for treating existing illnesses, such as diabetes (diabetes mellitus), fat metabolism disorder, gout, etc.

Habits

• Restrict caffeine consumption, such as coffee.
• Drink only moderate amount of alcohol.
• Avoid smoking.

Physical Activities

• Exercise regularly.
• Choose sports that require stamina over those that require strength.
• Do not over exert and/or avoid reaching the limits of your performance.
• If you have a pre-existing condition and/or you are over 40, please consult your healthcare provider before starting any physical activities.

SmartCheck Technology

SmartCheck technology is an innovative concept to achieve optimum reliability in self-measurement of blood pressure. Highly accurate measurement result is achieved by the automatic analysis of three successive measurements (see section 5.5 Measuring Procedure). As human blood pressure is dynamic and can fluctuate, the SmartCheck technology provides a convenient way to obtain an accurate measurement, even during arrhythmia. This results in greater accuracy when compared to the calculation of average result.

Measurement specification

• The total measurement time for a full measurement cycle is less than 3 minutes, as opposed to a single measurement time of about 1.5 minutes.
• Single results are not displayed.
• Based on data analysis result, a 4th measurement may be applied.

Irregular Heartbeat Detection (IHD)

The appearance of the symbol indicates that certain pulse irregularity is detected during measurement. This may cause results to vary from your normal blood pressure levels. In general, this is not a cause for concern. However, if the symbol appears more frequently than usual, it is recommended that you consult with your healthcare provider. If SmartCheck™ measurement mode is used, irregular heartbeat detected during measurement will not affect results (see section 2.3 for more information).

Note: The device detects early stage pulse irregularities. It is not a replacement for cardiac examination.

Vaunn Medical vB100A Digital Upper Arm B.P Monitor Traffic Light Indication

The colored bars on the left edge of the display indicate the range within which the measured blood pressure values lie. Depending on the height (or number) of the bars, the measured values are either within the normal (green), elevated/hypertension stage 1 (yellow) or hypertension stage 2 (orange/red) range. The classification corresponds to the 4 levels as defined by the American Heart Association (AHA). Please refer to the table in section 2.2 to learn more. In addition, the 3-color backlight display shows different color according to the measured blood pressure values. Readings in the classification range of 1 is shown in green backlight, classification ranges of 2, 3 in yellow backlight and classification ranges of 4, 5, 6 in red backlight.

Operating the Blood Pressure Monitor

Before Taking Measurement

• Avoid eating, smoking, and any strenuous activity such as exercise before measurement. These factors can influence the measurement result. It is recommended that you relax for about ten minutes before measurement. Example: sitting in an armchair in a quiet environment.
• Remove any tight or constricting garment around the upper arm.
• Always measure from the same arm – typically the left arm.
• Attempt/plan to carry out measurement regularly around the same time of day as blood pressure changes during the course of the day.

Common Sources of Error

Note: Comparable blood pressure measurements require and/or are dependent on the same conditions.

• Any effort by the user to support his/her arm during measurement can increase the blood pressure values. Therefore, make sure that the user is in a comfortable, relaxed position and does not activate any muscles of the arm during measurement. Use a cushion for support if necessary.
• If the arm artery lies considerably lower (higher) than the heart, an erroneously higher (lower) blood pressure will be registered. Each 15 cm (5.9 inches) difference in height results in a measurement error of about 10 mmHg.
• An arm cuff that is too narrow or too short will result in false measurement values. Using the correct size cuff is crucial in getting accurate measurement values. The cuff size is dependent on the circumference of the arm, measured at the center. Note: only use Vaunn Medical arm cuff.
• A loose cuff or sideways protruding air pocket causes false measurement values.
• Repeated measurements cause blood to accumulate in the arm. This can lead to false results. Therefore, it is recommended to pause for at least 1 minute between measurements.

Description

The Vaunn Medical vB100A Digital Upper Arm B.P Monitor is a clinically approved device that is suitable for both home and professional use. This monitor features a large LCD screen that displays clear and easy-to-read measurements. It can measure blood pressure and pulse rate simultaneously and has an irregular heartbeat detection feature. The cuff fits arm circumferences of 9 to 17 inches, making it suitable for most adults. The device has a memory function that stores up to 120 readings, and it can detect and display an average of the last three readings.

Fitting the Arm Cuff

a. Pass the end of the cuff (with sewn-in rubber stopper) through the metal D-ring to form a loop. The Velcro closure should be facing outward. If assembled correctly, the metal D-ring should not touch the skin whenthe cuff is looped around the arm. Note: Skip this step if the cuff has already been prepared.
b. Insert left arm through the cuff loop and position the cuff on the upper arm. The tube should point in the direction of the lower arm.
c. Adjust the cuff position on the upper arm. The lower edge of the cuff should be approximately ¾-1” (2-3cm) above the elbow. The tube and “ARTERY MARK” should be aligned with the inner side of the arm. Important: The red line along the edge of the cuff must lie exactly over the artery which runs down the inner side of the arm.
d. Tighten the free end of the cuff and secure with the Velcro closure. The cuff should fit snugly on your upper arm such that you can fit2 fingers between the cuff and your upper arm. Any clothing that restricts the arm should be removed prior to measurement.
e. Lay the arm on the table or support cushion with the palm upward. The arm cuff should be at the same level as the heart. Check to make sure that the tube is not kinked.
f. Remain seated comfortably for abou ttwo minutes before starting measurement.

Note: If it is not possible to fit the cuff on the left arm, it can also be placed on the right arm. However, for consistency, measurements should only be taken from the same arm.

Measurement Mode Selection

You can choose between single or SmartCheck™ measurement mode.

• Single mode

  • Slide the mode switch (on the right-hand side of the measuring unit) towards “1”.

    

  • In single mode, 1 measurement will be taken.
• SmartCheck mode
  • Slide the mode switch towards “3”.
  • In SmartCheck mode, 3 measurements will be taken in succession and final results will be calculated automatically.
  • The symbol on the screen display indicates that the device is set to measure in SmartCheck mode.

Measuring Procedure

Before taking measurement, make sure that the arm cuff has been applied and positioned correctly.

1. Press the Start/Stop button. The pump will begin to inflate the cuff. The display shows the increasing cuff pressure during inflation.

2. The pump will stop once inflation pressure has been reached. Cuff pressure will start to decrease slowly. Similarly, the display shows the decreasing cuff pressure during deflation.

   

3. When the device detects the pulse, the heart symbol begins to blink on the display and a beep tone will register with every pulse beat.

   

4. When measurement is complete, a long beep tone will register. The measured systolic and diastolic blood pressure values as well as the pulse rate are displayed. Traffic light indicator bars and colored backlight will be displayed according to the classification ranges in which the measurement results lie.

5. If the symbol  appears on the display, it indicates that an irregular heartbeat has been detected during measurement. This may cause results to vary from your normal blood pressure levels. It is recommended that you retake your measurement after a brief pause of at least 1 minute. It is important that you remain relaxed, still, and do not talk during measurement.

   

   
   Note: If the symbol appears more frequently than usual, it is recommended that you consult with your healthcare provider.

6. The measurement results will remain on the display until the device is switched off by pressing the Start/Stop button . If the button is not pressed within 1 minute, the device will switch off automatically to save power.
7. If the device is set to SmartCheck measurement mode, it will take 3 separate measurements in succession and calculate the analyzed blood pressure values. There will be 15 seconds resting time between measurements. During this resting period, the symbol will blink on the display and time will count down. You will hear a beeping sound during the last 5 seconds.
   Note
   • If measured data from each cycle differs too much, a 4th measurement will be performed before final results are displayed.
   • In rare cases where the blood pressure values are unstable even after the fourth measurement, <<Err6>> will be displayed.

Discontinuing a Measurement

If it is necessary to interrupt and/or stop a blood pressure measurement for any reason (e.g. the user feels unwell), the Start/Stop button can be pressed at any time. The device will immediately decrease the cuff pressure.

Switching Device Off

To switch the device off, press the Start/Stop button. If no activity is detected within 1 minute, the device will switch off automatically.
