hypertensive people do not realize they are at risk until their health is seriously threatened.

What is the standard blood pressure classification?

The following chart (Figure 3) was taken from the World Health Organization (WHO), and describes the various classifications.

Please note:

·Hypotension value is for reference only.

·Blood pressure is considered high when either the diastolic or systolic blood pressure value exceeds the normal range.

(high pressure)

·Only a physician can tell you your normal blood pressure range and the point at which you are at risk. Consult your physician to obtain these values. If the measurements taken with this product fall outside the range, consult your physician.

Why does my blood pressure fluctuate throughout the day?

Individual blood pressure varies greatly both on a daily and a seasonal or temperature basis. These variations may be more pronounced in hypertensive patients. Normally the blood pressure rises while at work and is at its lowest during sleep. Figure 4 below illustrates the variations over a single day with measurement taken every five minutes. The thick line represents sleep time. The rises in blood pressure at 4 PM (A in the graph) and 12AM (B in the graph) correspond to an attack of pain and sexual intercourse (Beven, Honour & Stott, Clin. Sci. 36:329, 1969).
