Alarms
Suction Disconnect Feature
Press and hold the Alarm Silence button for one second or longer
(until the ventilator sounds a short tone) to enable the Suction
Disconnect feature. With this feature enabled the ventilator will
automatically silence all patient and disconnect alarms, display
the message Ventilation Suspended, disable automatic leak
compensation, and deliver a bias flow of 10 L/min for Adult or 5 L/
min for Ped/Infant patient types if the ventilator senses that the
patient circuit has been disconnected. The ventilator will not deliver
breaths until the breathing circuit is reconnected or three minutes has
elapsed. When the ventilator detects reconnection or three minutes
has elapsed the ventilator will resume normal function.
NOTE: The ventilator recognizes the reconnection of the circuit
by reading the expiratory ow. Do not use the Suction Disconnect
feature if the flow sensor on the ventilator is defective, failing
calibration or disconnected.
Alarm Reset Button
See Figure 5-1
Audible alarms are automatically silenced when the alarm violation no
longer exists; however, visual alarm indicators do not automatically
reset. When an alarm violation is no longer active the alarm indicator
stops flashing and remains steadily lit to signal a latched alarm.
Press the Reset button to individually clear these alarm indicators.
