Note: One or two readings will not provide a true indication of your normal blood pressure. It is important
to take regular, daily measurements and to keep accurate records. Communicating your findings to your
doctor can be a valuable aid in diagnosing and preventing potential health problem.
The World Health Organisation (WHO) developed the Blood Pressure Classification indicated in the
following chart (1999 – revised in 2003). This classification, however, is only a general guideline,

It is advisable to consult your doctor to determine your normal blood pressure.
