The Alarm Silence Indicator. Lights continuously when an audible
alarm has been silenced. It flashes when the alarm silence duration
has been set to
OFF.
The Interference Indicator. Lights whenever the OXIMAX software
detects that the incoming signal qu
ality is degraded due to
interference (see Interference Explained on p
age 11).
An intermittently lit
Interference indicator is common during patient
monitoring, and indicates that the O
XIMAX algorithm is dynamically
adjusting the amount of data required for measuring SpO
2
and Pulse
Rate. When lit continuously, it indicates that the O
XIMAX algorithm
has extended the amount of data required for measuring SpO
2
and
Pulse Rate, and, consequently, fidelity in tracking rapid changes in
these values may be reduced (see Description of Displays and
Indicators on page 9).
The Pulse Search Indicator. Lights continuously prior to initial
acquisition of a pulse signal and during
prolonged and challenging
monitoring conditions. It flashes during a loss-of-pulse signal.
The Sensor Off Indicator is lit when either the sensor is invalid, or no
longer on the patient’s finger. It usually indicates that the sensor is
not
on the patient.
The Sensor Message Indicator. Lights when the N-560 cannot
determine an SpO
2 level or a pulse rate. The sensor message
recommendations for improving the signal are:
• Reposition sensor
• C
heck or change adhesive wrap
• Choose alternate site
•Warm site
• Cover sensor
• Use forehead, nasal, or ear sensor (adult patients only)
•Use O
XIMAX adhesive sensor
• Secure cable
