Blood Pressure Monitoring Guide

Basically, blood pressure is a measure of the force against the walls of your arteries. Arterial blood pressure is constantly changing during the course of the heart’s cycle.

The highest pressure is called the Systolic Blood Pressure; the lowest the Diastolic Blood Pressure. Both pressure readings, are necessary to enable a doctor to evaluate the status of a patient’s blood pressure.

A reading between 135 mm Hg (millimetres of Mercury), Systolic and 85 mm Hg Diastolic is considered normal.

According to World Health Organisation, and International Society for Hypertension, blood pressure should normally be less than 140 / 90 mm Hg but above 120 / 80 mm Hg for an adult. Blood pressure that stays between 140 -160 / 90 – 95 is considered critical (mild Hypertension), and above this level (160 / 95 mm Hg or higher) is considered high (Hypertension). The values indicated above may differ by region and country.

Obesity, alcohol, smoking, lack of exercise and the stress of life causes high blood pressure, also high blood pressure can be hereditary.

Without treatment, high blood pressure can lead to numerous health problems including heart attacks, kidney problems. It is also one of the most common causes of strokes.

To lower blood pressure, eat a balanced diet with fruit, fresh vegetables. Avoid animal fats and use less salt. Try to drink less alcohol and exercise more, stop smoking.

Irregular Heartbeat is a condition where the heartbeat rhythm varies by more than 25% from the average heartbeat detected while your unit is measuring the blood pressure.

Generally Blood Pressure Monitors have an irregular heartbeat detector. If such an irregular rhythm is detected, the irregular heartbeat symbol appears on the display. If this happens frequently during blood pressure measurement it is recommended that you discuss this with a healthcare professional.

There are are several reasons why you may have inconsistent readings. Many factors exist that can cause a variation in blood pressure measurement values, for example, recent activities or even the time of day can alter the reading.

  • User’s technique is very important for reliable measurement results. Listed below are some of the common reasons you may see an inconsistent or inaccurate reading:
  • Blood Pressure Monitors are not intended for use during exercise or activity, you should avoid eating, smoking and exercising for at least 30 minutes before taking a measurement.
  • Before Taking a Measurement avoid eating, drinking alcohol, smoking, exercising, and bathing for 30 minutes and rest for 15 before starting the measurement. Avoid taking a measurement during stressful times. Take the measurement in a quiet place.
  • Sit in a chair with your feet flat on the floor. Rest your arm on a table with your palm facing upward. The cuff should be level with your heart. Do not talk or move during the measurement.
  • Cuff Size is important to use the appropriate size cuff for your arm to obtain accurate measurement results when using your blood pressure monitor. If the incorrect cuff is used the result may be an inaccurate reading.
  • Proper cuff application also important to obtain correct measurements.

Is an upper arm blood pressure Monitor more accurate than a wrist type?

Both of these devices must meet the same specifications for accuracy. Pressure: +/- 3 mm Hg (millimetres of Mercury), Pulse: +/- 5% of display reading. These values meet or exceed the provisions of EC directive 93/42/EEC and the European Standard EN1060.

The choice of device is basically one of convenience. Some people find the compactness of a wrist blood pressure monitor a benefit especially if one is travelling. Others prefer the larger buttons and display on the upper arm blood pressure monitors.

 

What size cuff do I need?

It is very important to use the appropriate size cuff for your arm to obtain accurate measurement results when using your blood pressure monitor. In order to determine the appropriate cuff size, you need to measure the circumference of your arm. This is especially true if you have a borderline arm size measurement, or you may have gained or lost weight.
It is important to ensure the arm cuff you are using with your monitor is the correct size for you. If the incorrect cuff is used the result may be an inaccurate reading and/or the cuff will be damaged.
To determine your arm size, use a cloth tape measure and place the tape measure midway between your elbow and your shoulder around the circumference of your upper arm. Wrap the tape measure evenly around your arm. Do not pull the tape tight. Note the precise measurement in centimetres.

Omron Blood Pressure Monitors Standard Cuff Sizes :
Small Cuff            – arm sizes 17– 2 cm
Medium Cuff         – arm sizes 22–32 cm
Large Cuff –          – arm sizes 32–42 cm
Wide Range Cuff – arm sizes 22-42cm

Comfort Cuff Sizes:
The Comfort Cuff will fit arms 22 – 42 cm.

How do I assemble and use the upper arm cuff?

When the cuff is assembled correctly, the Velcro hook material will be on the outside of the cuff loop and the metal ring will not touch your skin. If the cuff is open, pass the end of the cuff furthest from the tubing through the metal ring to form a loop. The smooth cloth should be on the inside of the cuff loop.

  1. Remove tight-fitting clothing from your upper arm.
    2. Sit in a chair with your feet flat on the floor.
    3. Put your left arm through the cuff loop. The bottom of the cuff should be about 1 – 2 cm above your elbow (thickness of your index or middle finger). Adjust the cuff around your arm so that the tubing runs down the centre of your arm in line with your middle finger (palm open and facing upwards).
    4. Secure the cuff around your arm using the cloth closure. Pull the cuff so that the top and bottom edges are tightened evenly around your arm.
    5. The cuff should be firmly secured but not too tight – just enough so that it is difficult to slide 2 fingers under the cuff. This space is imperative for an accurate reading.
    6. Relax your arm and place your elbow on the table so that the cuff is at the same level as your heart. Turn the palm of your hand upward.
    7. Check there are no kinks in the air tubing. Be careful that you do not rest your elbow on the air tube when taking a blood pressure reading.
    8. Press the ‘START’ button to begin the blood pressure reading.

How do I know if the arm cuff is wrapped too tight or too loose?

Small, Medium or Large Cuff:
It is recommended that you apply the cuff using the following directions:

Why can the measurement values differ when measurements are taken on the right and left arm?

Blood pressure measurement values vary from the left arm to the right arm. The average is generally within 10 mm Hg (millimetres of Mercury) for most individuals. The user should consult a doctor before using the right arm to take a measurement. The doctor can assist the user in determining their measurement values for the right arm.
The cuff is designed mainly for use on the left arm. All validation testing is done on the left arm for the general population.


How do I compare the readings on my blood pressure monitor with my doctor’s readings?

When using your unit at home your readings may be lower due to a more relaxed environment. If you want to compare home measurement readings to those taken with the device used by your healthcare professional please follow this direction;
use the Blood Pressure Monitor to take the first measurement followed by the unit used in the healthcare professional office. It is necessary to use the digital unit first because of the different methods used in the devices.
Blood Pressure Monitor measures the movement of blood through your arteries and converts this into a digital reading (Oscillometric method). A doctor typically uses a stethoscope (to listen to the sounds in the artery) and a gauge for the pressure reading (Auscultation method). The artery is constricted during the measurement so it is important to wait a few minutes between measurements to allow the artery to recover.
Please bear in mind that blood pressure is constantly fluctuating therefore a small difference can be expected in the readings between the Blood Pressure Monitor and the doctor’s unit.
