Description of Controls, Indicators, and Symbols
10
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 O
XI
M
AX
software detects
that the incoming signal quality is degraded due to interference (see
Interference Explained on page 11).
An intermittently lit
Interference
indicator is common during patient
monitoring, and indicates that the O
XI
M
AX
algorithm is dynamically
adjusting the amount of data required for measuring SpO
2
and Pulse Rate.
When lit continuously, it indicates that the O
XI
M
AX
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
• Check or change adhesive wrap
• Choose alternate site
• Warm site
• Cover sensor
• Use forehead, nasal, or ear sensor (adult patients only)
• Use O
XI
M
AX
adhesive sensor
• Secure cable
• Secure with headband ( M
AX
- F
AST
)
• Remove nail polish
