Why Measure Blood Pressure at Home?
Blood pressure measured at a clinic or doctor's office may cause apprehension and can produce an elevated
reading, 25 to 30 mmHg higher than that measured at home. Home measurement reduces the effects of outside
influences on blood pressure readings, supplements the doctor's readings and provides a more accurate, complete
blood pressure history.
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 at the right.
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 the date and time when recording
your blood pressure. Consult your doctor to interpret your blood
pressure data.
