making a blood pressure measurement 7
7.3 the right measuring position
-
Have yourself on a seat in a comfortable position, breathe
deeply several times and relax.
-
Measure the blood pressure the same time every day. To get
a correct picture of the blood pressure changes during the day,
make the measurements at home daily at the same time.
-
Place your elbow on the table or other suitable support and
hold the cuff so that the cuff is at the same level as the heart.
-
Record the values and show them to your physician for
assessment.
notes :
If the cuff is not pulled tight you get wrong measure values. The blood pressure value measured
on the wrist may be different from that on the upper arm. As the measuring positions and the
size of the blood vessels are different on the wrist and upper arm, the values may differ slightly.
In many cases the difference can be ± 10 mmHg systolic and diastolic in a healthy person.
Holding your arm in too high or too low a position when measuring your blood pressure (see
illustration) results in a measurement error of 10 mmHg per 15 cm of height differential. The
following groups should watch their blood pressures in particular: hypertonic persons, diabetic
patients, persons with liver disease, hardened arteries, circulatory weakness, etc.
