xiv
Wear the cuff at the same level as heart. (If the level is
different, an error in the measurement value occurs.)
The recorder responds to artifact and external impact. If there
are any doubts in the measurement value, measure blood
pressure by auscultation or palpation.
A measurement error may occur if the cuff is not of the correct
arm circumference for the patient.
Do not inflate the cuff before it is wrapped around the arm of
the patient. Damage and explosion of the cuff may occur.
Note
Blood pressure measurement may cause subcutaneous bleeding.
This subcutaneous bleeding is temporary and disappears with time.
If the patient uses a heart-lung machine, blood pressure cannot be
measured due to the absence of a heartbeat.
Blood pressure cannot be measured correctly if thick clothing is
worn.
Blood pressure cannot be measured correctly if the clothing is rolled
up and the arm is squeezed.
Blood pressure cannot be measured correctly if peripheral
circulation is insufficient, the blood pressure is excessively low
or if the patient has hypothermia (blood flow is insufficient).
Blood pressure cannot be measured correctly if the patient has
frequent arrhythmia.
Blood pressure cannot be measured correctly with the incorrect
cuff size.
Blood pressure cannot be measured correctly if the cuff is not worn
at the same level as the heart.
