TABLE 1: Blood pressure value and risk classification according to the recommendations of
the World Health Organisation.
Further Information
• If your values are normal under resting conditions but exceptionally high
under conditions of physical or psychological stress, it is possible that
you are suffering from “labile hypertension”. Consult your doctor if you
suspect this may be an issue.
• If the systolic and diastolic blood pressures fall into non-corresponding
categories, the higher category determines the hypertensive risk. For
example, a systolic pressure of 185 and a diastolic pressure of 95 is
classified into the severe hypertension category.
• The monitor is equipped with a Risk Category Indicator that classifies
measurements into options based on the WHO blood pressure risk
classifications. See Table. 1.
• At the completion of the measurement, an arrow on the LCD display will
automatically position the result into the correct segment of the coloured
Risk Category Indicator, to confirm your present risk.
• Measured diastolic blood pressure values above 120mmHg require
immediate medical treatment.
