Mode-Specific Alarms
Disconnect Alarm
If the tracheostomy tube becomes disconnected from the patient
circuit, a high urgency Disconnect Alarm will sound. When the
disconnect alarm is active, the ventilator continues ventilation. If the
tracheostomy tube becomes re-connected, the alarm auto-resets.
Airway Occlusion Alarm
If the area surrounding the tracheostomy tube becomes obstructed
during ventilation in Speaking Mode (e.g., the tracheostomy cuff is
inflated) so the flow rate through the patient's airway during exhalation
is less than 5 L/min for the entire exhalation, a high urgency airway
occlusion alarm will sound. The ventilator continues to ventilate and
the exhalation valve closes during inhalation only.
The airway occlusion alarm will auto-reset when an exhalation occurs
that does not meet the alarm condition. The airway occlusion alarm
cannot be silenced by the alarm silence key.
