Alarm
Silence
Function: Disables the audio alarm for two minutes. When Alarm Silence is
pressed before the end of a two-minute period, the two-minute timer is
reset. Alarms that cannot be silenced are listed in Table 9-1: “Alarm Alert
Messages” on page 9-5.
Indicator: Illuminated yellow when the audible alarm has been disabled; is
active and stays on for two minutes when the ALARM SILENCE button is
pressed. If ALARM SILENCE is active, and a new alarm condition occurs,
which involves exceeding an active alarm limit, the visual alarm functions
will be active. (Refer to “Alarm Silence” on page 9-2.) ALARM RESET
clears ALARM SILENCE. If a medium or high priority alarm exists after
ALARM RESET clears ALARM SILENCE, the audible alarm will begin.
Alarm
Reset
Function: Clears the visual indicator for auto reset alarms, certain active
alarms (see “Alarm Reset” on page 9-3), and reset of apnea ventilation
back to the active mode of ventilation (see “Apnea Ventilation” on page 8-
27). Alarm Reset also terminates ALARM SILENCE.
NOTE: The ventilator may automatically reset certain types of alarm
conditions once the causes of the alarms are corrected. After an
automatic reset, the ventilator will clear the audible alarm and will
display a Low Urgency Alarm alert in the Alert Message Insert to
inform the operator that an alarm condition existed. When this
situation occurs, use ALARM RESET to clear the visual alarm
indicator.
