NIBP Measurement Limitations
The measurement may be inaccurate or impossible in the following situations:
•
Regular arterial pressure pulses are hard to detect
•
Excessive and continuous patient movement such as shivering or convulsions
•
Cardiac arrhythmias
•
Rapid blood pressure changes
•
Severe shock or hypothermia that reduces blood flow to the peripheries
•
On an edematous extremity
•
Obesity, where a thick layer of fat surrounding a limb dampens the oscillations coming from the artery
Note
•
The performance of NIBP module in dialysis patients was evaluated and the results showed
a reliable measurement of the NIBP module in theses patient.
•
The performance of NIBP module in pregnant women was evaluated and the results showed
a reliable measurement of the NIBP module in theses patient.
Warning
•
For people who have low peripheral blood flow, significantly low blood pressure, or
significantly low body
temperature, measurement may not be possible (an error will occur)
or the measurement result may not be reliable due to insufficient blood flow in the
measurement location.
•
Measurement reliability will decrease if the user moves or speaks during measurement, or
the body position is
not correct.
•
Measurement reliability will decrease if the arm is compressed because a garment with thick
sleeves is worn or
the sleeves are rolled up.
