Indicators and Icons
Alarm Bar LED
This LED indicates all alarm conditions. For high priority (patient) alarms, the
indicator is displayed in red, blinking fast. For medium priority alarms, the
indicator is displayed in amber, blinking slowly.
Pulse Quality LED
This amber LED blinks to indicate an inadequate pulse signal. If there is a sustained
period of poor quality signals, this LED will display a steady, constant light.
Sensor Alarm LED
This amber LED indicates when a sensor has become disconnected, has failed,
or is not compatible with this monitor.
NOTE:
In the 7500FO, the Sensor Alarm LED latches. Sensor must be properly attached to
patient and alarm silence button must be toggled to clear LED.
WARNING: Do not use a damaged sensor. If the sensor is damaged in any way,
discontinue use immediately and replace the sensor.
Pulse Strength Bargraph LED
This 8-segment tricolor bargraph indicates pulse strength as determined by the
oximeter. The height of the Pulse Strength Bargraph LED is proportional to the
pulse signal, and the color is determined by pulse strength:
Green
= a good pulse strength
Amber
= a marginal pulse strength
Red
= a low pulse strength, high priority alarm
Alarm Silence LED
This amber LED indicates that the audible alarm is silenced for two minutes
when it blinks. When alarms are active, this LED blinks in time with the alarm
bar. If no alarms are active, this LED flashes at the medium priority alarm rate.
When lit solid, the Alarm Silence LED indicates that audible alarm volumes are
set to less than 45 dB.
