Note:
Trigger Type is not
available when an Active PAP
or Active Flow circuit is selected.
Flow trigger is the triggering
method used for Active PAP and
Active Flow circuits.
Note: Flow Trigger with leak
compensation is only available if
the Active Flow circuit is selected.
Note:
Enabling Leak
Compensation when using the
Active Flow Circuit configuration
only affects triggering and does
not affect tidal volume delivery
or Vte measurement.
Note: Auto-Trak is only
available if the Passive Circuit is
selected.
2. Trigger Type
The device can be set to trigger breaths based on automatic flow
thresholds or specific flow settings. You can select Auto-Trak or
Flow Trigger as the Trigger Type. When Auto-Trak is selected, the
Auto-Trak trigger initiates based on automatic flow thresholds.
When Trigger Type is set to Flow Trigger, Flow Trigger Sensitivity
Leak Compensation, and Flow Cycle Sensitivity become active,
and the trigger initiates based on the Flow Trigger Sensitivity
setting.
3. Flow Trigger Sensitivity
If you set the Trigger Type to Flow Trigger, the Flow Trigger
Sensitivity setting displays. You can increase or decrease the
setting from 1 to 9 l/min in 1 l/min increments.
The flow trigger initiates when the patient’s inspiratory effort
creates a flow equal to or greater than the flow sensitivity
setting.
4. Leak Compensation
If you are using an Active Flow circuit, you can turn Leak
Compensation On or Off.
5. Flow Cycle Sensitivity
If you set the Trigger Type to Flow Trigger, the Flow Cycle
Sensitivity setting displays. You can increase or decrease the
setting from 10 to 90 percent (%) in 1% increments.
As flow begins to decrease during inspiration, if the patient
flow is less that the flow cycle set point, the device will cycle to
expiration. For example: if the flow cycle is set to 25%, when the
flow has decreased by 25% of the peak flow, the device will cycle
to the EPAP/PEEP level.
6. Ramp Length
The Ramp Length allows you to set the ramp time. You can
disable Ramp by selecting Off, or you can increase or decrease
the Ramp Length setting from 5 to 45 minutes in 5-minute
increments.
