Troubleshooting
156 N-600x Operator’s Manual
The Pulse Search Indicator
illuminates after successful
measurements have been made. • Check the status of your patient.
• Perfusion may be too low for the monitor to
track the pulse. Test the instrument on another
patient. Change the
O
XI
M
AX
sensor site and/or
try another type of O
XI
M
AX
sensor.
• Interference may be preventing the N-600x
from tracking the pulse. Verify 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 tolerates more
patient movement; for example, an adhesive
O
XI
M
AX
sensor. Electromagnetic interference
may be preventing the N-600x from tracking
the pulse. Remove the source of interference
and/or try to stabilize the environment.
• The O
XI
M
AX
sensor may be too tight, there may
be excessive ambient light, or the O
XI
M
AX
sensor may be on an extremity with a blood
pressure cuff, arterial catheter, or intravascular
line. Reposition the
O
XI
M
AX
sensor, as
necessary.
