Ensuring Accurate Monitoring
While each sensor requires site specific application procedures, the following
general points aid in ensuring oximetry monitoring success.
• Choose a site that provides proper alignment of the LEDs and receiving
photodetector.
• Reduce light interference when monitoring a neonate under bright light by
using a diaper or other light block over the sensor.
• Select a site that has unrestricted blood flow and can remain as immobile as
possible to reduce or eliminate movement artifact.
• Do not restrict blood flow when securing a sensor with tape.
• Do not select a site near potential electrical interference (electrical cords, for
example).
• The Sensorwatch bar should be above the minimum signal level.
Using the Sensorwatch Feature
The Sensorwatch feature is a graphical presentation of the amplitude of the signal
received from the sensor. It can be used to determine the best sensor site and
application.
Changes in the displayed shaded level signify the changes in the patient’s
perfusion or changes in the application of the sensor. The horizontal line near the
bottom fourth of the graphic represents the minimum signal level that results in
accurate saturation values. When the shading is just below this point, the
message LOW SIGNAL STRENGTH - REPOSITION OR REPLACE SENSOR is
displayed and SENSORWATCH flashes.
When the shading is below the line:
• Reposition the sensor to a different site to provide better perfusion.
• Reposition the sensor so that better contact is made with the skin and the
LEDs and photodetector are aligned better.
• Replace a defective sensor.
• Wait for the patient to warm and the perfusion to increase.
Setting and Adjusting Alarm Limits
Pulse oximetry alarm limits and delays are based either on factory default limits or
user-defined limits. The factory default settings for alarm limits are 100% for high
and 85% for low. For alarm delays, the factory default settings are 15-seconds for
alarm limit delay and 20-seconds for message alarm delay. Refer to Alarms on
page 2-3 for further information concerning Ultraview Care Network alarm
operations.
