In Assist Control (AC) mode, the device delivers volume control 
therapy. This mode provides Assist and Mandatory breaths. An Assist 
breath is started when there is patient effort, but it is ended when 
the Inspiratory Time setting has been met. A Mandatory breath 
is delivered if the patient does not spontaneously breathe within 
the prescribed BPM setting. This ensures that the patient receives 
a minimum number of breaths per minute. In this mode, the Tidal 
Volume is delivered during inhalation and PEEP is delivered during 
exhalation. The following illustration describes these concepts.

In Synchronized Intermittent Mandatory Ventilation (SIMV) mode, the 
device delivers both volume control and pressure control therapy. 
This mode provides Spontaneous, Assist, and Mandatory breaths. 
This mode uses a time window to decide what type of breaths should 
be delivered. This time window is the maximum time between 
breaths according to the set Breath Rate.

When you enter SIMV mode, the time window is started. If the 
patient does not provide any effort, the ventilator will provide a 
Mandatory Volume breath when the time expires and then begin the 
process again. Mandatory breaths deliver the Tidal Volume setting 
during inhalation and provide a lower Peak End Expiratory Pressure 
(PEEP) during exhalation.
