• Check the sensor directions for use to determine if
an appropriate sensor is being used and if it is
applied properly. Check sensor and extension cable
connections. Test the sensor on another subject.
Try another sensor or extension cable.
• Perfusion may be too low for the monitor to track
the pulse. Check the patient. Test the monitor on
yourself. Change the sensor site. Try another
sensor.
• Interference due to patient activity may be
preventing the monitor from tracking the pulse.
Keep the patient still, if possible. Verify that the
sensor is securely applied and replace it, if
necessary. Change the sensor site.
• The sensor may be too tight, there may be
interference due to ambient light, or the sensor may
be on an extremity with a blood pressure cuff,
arterial catheter, or intravascular line. Reposition
sensor, as necessary.
• Electromagnetic interference may be preventing
the monitor from tracking the pulse. Remove the
source of interference.
