THE CORRECT MEASURING POSITION
Perform the measurement while seated. Pay attention to the following:
Make sure you are in a comfortable sitting position,
Do not cross your legs,
Place your feet at on the oor,
Support your back and arm,
Place the centre of the cu at the height of the right atrium.
Relax your arm and place it on a table, for example. Remain calm and
relaxed during the measurement. Do not move or speak, as this may
change the measurement results.
The following must be noted when taking the blood pressure:
Seated measurement after 3-5 minutes of rest prior to the measurement
At least two blood pressure measurements at an interval of 1 to 2
minutes in a seated position and additional conrmation measure
ments, if the rst two measurements dier signicantly. The averaging
of the blood pressure values may be considered.
Repeat the measurements in order to improve the accuracy for patients
with arrhythmias, e.g. atrial brillation.
The cu must be positioned at heart height.
For auscultatoric methods, pay attention to the disappearance of the
Korotko sounds to identify the systolic and diastolic blood pressure
(phase I and V).
The blood pressure should be measured on both arms as part of an
initial examination. The higher blood pressure value is the reference
value.
In order to detect orthostatic hypotension for older patients, diabetics
or other common illnesses, the rst measurement should take place
while standing, after 1 and 3 minutes.
For conventional blood pressure measurements, the heart rate should
be detected by feeling for the pulse (at least 30 seconds) in a seated
position after the second measurement.
