How to interpret a High Blood Pressure Reading

How to interpret (read) a High Blood Pressure Reading
Question and answer.

Q - What do the different parts of a high blood pressure reading signify?
A - When blood pressure(BP) is measured, it's written as a fraction.

Systolic BP/Diastolic BP and it is measured in mmHg (Millimeters of mercury)

As you can see from the above illustration of the high blood pressure reading, the numerator or upper number represents the systolic blood pressure while the denominator or lower number represents the diastolic blood pressure.

If the systolic BP is 120 mmHg and the diastolic BP is 70mmHg, then it is written as

120/70 mmHg

But when reporting a high blood pressure reaading verbally, like when you have discussions with your doctor, you say "120 over 70". If it's 140/90mmHg, you say "140 over 90"






Q - What is the best time to take my blood pressure?
A - Your blood pressure fluctuates during the day depending on the time and the activity you are involved in. To ensure consistency in your blood pressure readings, you should take your blood pressure at the same time everyday. E.g. In the mornings or at bed time.

Do not take coffee or cigarettes for at least 30 minutes before taking your reading. They contain substances that can affect high blood pressure readings.






Q - Are there any precautions that I should take?
A - In addition to the precautions already mentioned above, you should also know the following.

1. Do not take BP readings when you have a full bladder. Go and empty your bladder and rest for about 5 minutes before you take your reading.
2. If you're anxious, angry or frightened, your blood pressure can be higher than expected.
3. Make sure your arms are properly exposed to give room for attaching the monitor. And try not to wear shirts with tight sleeves as this can affect the reading.
4. Before you take your reading, rest for about 5 minutes, then measure. When you measure, sit on a chair with your back resting on the support, make sure both your feet are on the floor and place your arm and the monitor on a table at the level of your chest. This will provide a result that is closest to what your BP is throughout the day.
5. An average of two different readings taken at least 5 minutes apart is more reliable than 1 reading.





Q - Where Can I get a BP monitor?
A - You can get them at most reputable shops and pharmacies. Ask your health care provider for recommendations
