pressure is lowest (diastolic blood pressure value).
Blood pressure values must lie within certain normal ranges in order to
prevent particular diseases.
2.2. Which values are normal?
Blood pressure is too high if your diastolic pressure is above 100 mmHg
and/or your systolic blood pressure is over 160 mmHg,
while at rest
. In
this case, please consult your physician immediately. Long-term values at
this level endanger your health due to continual damage to the blood
vessels in your body.
If your systolic blood pressure values are between 140 mmHg and 159
mmHg and/or the diastolic blood pressure values are between 90 mmHg
and 99 mmHg, consult your physician. Regular self-checks are necessary.
If you have blood pressure values that are too low (i.e., systolic values
under 105 mmHg and/or diastolic values under 60 mmHg), consult your
physician.
Even with normal blood pressure values, a regular self-check with your
blood pressure monitor is recommended. You can detect possible changes
in your values early and react appropriately.
If you are undergoing medical treatment to control your blood pressure,
keep a record of values along with time of day and date. Show these
values to your physician.
Never use the results of your measurements
to independently alter the drug doses prescribed by your
physician.
Which values are normal?

been established by the National Institutes of Health JNC7, 2003.
