WHO Blood Pressure Classification
Standards to assess high blood pressure, without regard to age,
have been established by the World Health Organization (WHO),
as shown in the chart.
Blood Pressure Variations
An individual's blood pressure varies greatly on a daily and seasonal basis. It may vary by 30 to 50 mmHg due to various
conditions during the day. In hypertensive individuals' variations are even more pronounced. Normally, the blood
pressure rises while at work or play and falls to its lowest levels during sleep. So, do not be overly concerned by the
results of one measurement.
Take measurements at the same time every day using the procedure
described in this manual to get to know your normal blood pressure.
Regular readings give a more comprehensive blood pressure history. Be
sure to note date and time when recording your blood pressure. Consult
your doctor to interpret your blood pressure data.
