Maternal/Fetal Monitor
User Manual
Warning
If the NIBP measurement under the auto or continuous measure mode lasts too long, the
limb with the cuff may suffer from purpura, ischemia or nerve damage. During patient
monitoring, you should check the color, warmness and sensitivity of the far end of the limb
from time to time. Once you observe any anomaly, place the cuff on another place or stop
measurement immediately.
Attention
The patient should relax as much as possible and not talk during the measurement procedure.
5 min should elapse before the first reading is taken.
If unexpected readings are obtained, first the operator should use the same method to take
measurement and then check the monitor function.

Measurement Limitations
According to the patient's condition, oscillatory measurement has some restrictions. Such measurements are
looking for regular impulse waves produced by arterial pressure. In case the patients’ condition makes this
kind of detection difficult, measurement values will become unreliable and load time will increase. Users
should be aware that the following conditions will interfere with the measurement method, so that pressure is
not reliable or load time increases. In this case, the patient's condition will make measurement impossible.
(1) Patient Mobility
If patient is moving, shaking or in spasms, measurement will be unreliable or even impossible, as these
may interfere with the detection of the arterial pressure pulse and load time will be extended.
(2) Arrhythmia
If patient has shown arrhythmia caused by irregular heart beats, measurements are unreliable or even
impossible and load time will be extended.
(3) Heart-Lung Machine
If patient is connected to an artificial heart-lung machine, measure cannot be conducted.
(4) Pressure Change
If within a certain time, arterial pulse pressure is being analyzed to get the measurements, when blood
pressure in patients is rapidly changing, measurement will be unreliable or even impossible.
(5) Severe Shock
If a patient is in serious shock or hypothermia, the pressure will be unreliable. The reducing blood
flowing to periphery would cause a decline in arterial pulse.
(6) Limit Heart Rate
