automatically according to the set time interval.
Warning
Prolonged non-invasive blood pressure measurements in Auto mode may be associated with purport,
ischemia and neuropathy in the limb wearing the cuff. When monitoring a patient, examine the
extremities of the limb frequently for normal color, warmth and sensitivity. If any abnormality is
observed, stop the blood pressure measurements.
4.
To stop auto measuring:
During auto measuring, press
button at any time to stop auto measurement.
5.
To start a manual measurement:
Press
button to start a manual measuring in the ordinary user working environment.
During the idle period of auto measuring process, press
button at any time to start a manual
measurement. Then press
button to stop manual measurement and the system continues
executing auto-measuring program.
Note
If you are in doubt about the accuracy of any reading(s), check the patient's vital signs by an
alternative method before checking the functioning of the monitor.
Warning
If liquid is inadvertently splashed on the equipment or its accessories, or may enter the conduit or
inside the monitor, contact local Customer Service Center.
Measurement Limitations
The oscillometry method has some limitations depending on the patient's condition. This measurement
is based on the regular pulse wave generated by arterial pressure. In the case where the patient’s
condition makes such a detection method difficult, the measured value becomes unreliable and the
measuring time increases. The user should be aware that the following conditions will make the
measurement unreliable or extend measurement time. In this case, the patient's condition will make the
measurement impossible
:
Patient Movement
Measurements will be unreliable or can not be performed if the patient is moving, shivering or
having convulsions. These motions may interfere with the detection of the arterial pressure pulse. In
addition, the measurement time will be prolonged.
Cardiac Arrhythmia's
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.
Heart-lung Machine
Measurements will not be possible if the patient is connected to a heart-lung machine.
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.
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.
Heart Rate Extremes
Measurements can not be made at a heart rate of less than 40 bpm and greater than 240 bpm.
Obesity patient
The thick fat layer of body will reduce the measurement accuracy, because the fat that come from
the shock of arteries can not access the cuffs due to the damping.
The following conditions may also cause changes in the blood pressure measurement value
After eating (within 1h), or having drinks containing alcohol or caffeine, or after smoking, taking
exercises or bathing;
Using incorrect posture such as standing or lying down, etc.;
The patient speaks or moves his body during measurement;
When measuring, the patient is nervous, excited, or in unstable emotion;
The room temperature rise or fall sharply, or the environment of measurement often changes;
Measuring in a moving vehicle;
