Trigger Type
The device can be set to trigger breaths based on automatic ow thresholds or specic ow
settings. Change the Trigger Type to one of the following options: Auto-Trak, Auto-Trak
[Sensitive] or Flow Trigger.
If Flow Trigger is selected then two set points will be available for adjustment: Flow Trigger
Sensitivity and Flow Cycle Sensitivity.
• Flow Trigger Sensitivity (Expiration to Inspiration)
The Flow Trigger Sensitivity may be adjusted from 1 to 9 l/min in 1 l/min
increments. The ow trigger initiates when the patient’s inspiratory eort creates a
ow equal to or greater than the ow sensitivity setting.
• Flow Cycle Sensitivity (Inspiration to Expiration)
The Flow Cycle Sensitivity may be adjusted from 10 to 90% in 1% increments. As
ow begins to decrease during inspiration, if the patient ow is less than the ow
cycle set point, the device will cycle to expiration.

O in increments of 0.5.
