WARNING
If liquid is inadvertently splashed on the equipment or its accessories, or it may enter the
conduit or inside the monitor, contact local Customer Service Center.
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.

Measurement Limitations
For different patient conditions, the oscillometric measurement has certain limitations. The
measurement is in search of regular arterial pressure pulse. In those circumstances when the
patient's condition makes it difficult to detect, the measurement becomes unreliable and
measuring time increases. The user 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.
z 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.
z 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.
z Heart-lung Machine
Measurements will not be possible if the patient is connected to a heart-lung machine.
z 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.
z 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.
z Heart Rate Extremes
Measurements can not be made at a heart rate of less than 40 bpm and greater than 240 bpm.
