Parameter Specification
Delay time from the onset of the
alarm condition to the point that
the representation of the alarm
condition leaves the signal out-
put port
< 10 ms from onset of the alarm condition to the
transmission of the signal
< 500 s until alarms received from the ventilator are
displayed on the IntelliVue patient monitor. This de-
lay is in addition to the alarm detection and process-
ing delays of the external device.
Remote alarm delay time The time it takes the message to appear on the re-
mote alarm depends on the characteristics of the de-
vice.
Maximum time from the alarm
condition triggering event to the
generation of an alarm signal
All alarms except those listed below: < 10 s
• Patient disconnect alarm: 11 s
• Proximal pressure line disconnect alarm: 15 s
• Low Inspiratory Pressure (LIP) alarm:
user-configurable from 5 to 60 s
• Check vent: Blower temperature high: 10 minutes
Mean delay, or the sum of mean
delays, from the triggering event
to the generation of an alarm sig-
nal
All alarms except those listed below: < 5 s
• Cooling fan failure alarm: 10 s
• Blower temperature alarm: 10 s
• ADC wraparound: 6 s
Audio alarm loudness

High-priority auditory alarm sig-
nal sound pressure level range,
measured per
ISO 3744:2010 ANSI/
