Blood pressure measurement error factors
The pulse graph can be an objective indicator
of the reliability of the measurement accuracy.
When noise occurs due to irregular heartbeat or
physical movements, the amplitude of the graph
changes. When the pulse graph is not a smooth
outline, check again or use other methods.
Cuff position at the same height as heart
Wrap the cuff around the arm at the same level as the heart. If the
cuff position is incorrect, a measurement error occurs. For example,
if the cuff is 10 cm lower than the heart level, the blood pressure is
measured 7 mmHg higher.
