How Is A Proper Measurement Made?
Blood pressure varies according to the conditions prevailing at the
time of measurement, so be sure to consider the following in order to
obtain the most accurate measurements.
1. In preparation for blood pressure measurement, the subject
should urinate and should remain relatively still for 10 to 15
minutes prior to measurement.
2.
Shirts or other garments which fit tightly on the upper arm should
be removed prior to fitting the arm cuff.
3. Exercise, eating and drinking, smoking,
etc., prior to measurement can affect the
results.
4. The blood pressure varies constantly
throughout the day. Measurement
should be made regularly at the same
time each day.
5.
Do not be too impressed by the results of
one measurement. Keep a record of
blood pressure variations. Many readings
tell a story.
6. When making repeated measurement,
the arm becomes heavy with blood,
resulting in wide variations in measure-
ment values. For this reason, repeated’
measurements should be made after a
rest period of approximately 5 to 10
minutes or after raising the arm to relieve
the engorged condition.
7. In general, the blood pressure is lower
in summer. (when it is hot) and higher in
winter (when it is cold).
8. Emotional stresses may tend to cause
blood pressure to rise.
