• Perfusion may be too low for the N - 560 to track the pulse. Check
the patient. Test the N-560 on someone else. Change the sensor
site. Try another type of sensor.
• Interference may be preventing the N-560 from tracking the
pulse. Verify that the
O
XI
M
AX
sensor is securely applied and
replace it if necessary. Change the
O
XI
M
AX
sensor site. Use a type
of
O
XI
M
AX
sensor that maintains better contact with the patient’s
skin, such as an adhesive
O
XI
M
AX
sensor.
• Electromagnetic interference may be preventing the N-560 from
tracking the pulse. Remove the source of interference (e.g.,
isolate the electromagnetic source or stabilize the sensor site). See
the caution in the EMI (Electro-magnetic Interference) section on
page 79.
• The sensor may be too tight, there may be excessive ambient
light, or the sensor may be on an extremity with a blood pressure
cuff, arterial catheter, or intravascular line. Reposition the sensor,
as necessary.

• Check the patient.
• Perfusion may be too low for the N - 560 to track the pulse. Test
the N-560 on someone else. Change the sensor site. Try another
type of sensor. Refer to
Sensor Performance Considerations on
page 70.
