NOTE:
The monitor is intended to measure NIBP for adults only.
Measurement Limitations -
To different patient conditions, the oscillometric measurement has certain limitations. The
measurement is in search of regular arterial pressure pulse. In those circumstances where the
patient's condition makes it difficult to detect, the measurement becomes unreliable and the
measuring time increases. You should be aware that the following conditions could interfere
with the measurement, making the measurement unreliable or longer to derive. In some cases,
the patient's condition will make a measurement impossible.
1) Patient Movement
Measurements will be unreliable or may not be possible if the patient is moving, shivering or
having convulsions. These motions may interfere with the detection of the arterial pressure
pulses. In addition, the measurement time will be prolonged.
2) Cardiac Arrhythmia
Measurements will be unreliable and may not be possible if the patient's cardiac arrhythmia
has caused an irregular heartbeat. The measuring time thus will be prolonged.
3) Heart-lung Machine
Measurements will not be possible if the patient is connected to a heart-lung machine.
4) Pressure Changes
Measurements will be unreliable and may not be possible if the patient's blood pressure is
changing rapidly over the period of time during which the arterial pressure pulses are being
analyzed to obtain the measurement.
5) Severe Shock
If the patient is in severe shock or hypothermia, measurements will be unreliable since reduced
blood flow to the peripheries will cause reduced pulsation of the arteries.
6) Heart Rate Extremes
Measurements can not be done to a patient whose heart rate is lower than 40 bpm or higher
than 240 bpm.
9.4.2 How to Apply NIBP Cuff
1) Select appropriate cuff for the patient.
The width of the cuff should be either 40% of the limb perimeter or 2/3 of the upper arm
length. The inflatable part should be long enough to encircle 50% ~ 80% of the limb.
The table below lists the reference size:
Type Limb Perimeter Cuff Size Air Hose Length
Upper Arm (Adult 1) 25 cm ~ 35 cm 14 cm
Upper Arm (Adult 2) 33 cm ~ 47 cm 17 cm
1.5 m or 3 m
