A/C-PC: Assisted/Control-Pressure Control
DESCRIPTION:
The A/C-PC mode provides pressure-controlled mandatory or assist-control breaths. When the Trigger Type is set to Off, the ventilator triggers and
cycles all breaths. When the Trigger Type is not set to Off, then the ventilator or the patient can trigger a breath, and the ventilator cycles all
breaths.

Flow Trigger
Sensitivity
This control is available when the trigger type is Flow Trigger. The flow trigger initiates when the
patient’s inspiratory effort creates a flow equal to or greater than the flow trigger sensitivity setting.

This control is available when the trigger type is Flow Trigger.
As flow begins to decrease during inspiration, if the patient flow is less than the flow cycle set point, the
device cycles to expiration.
