 Assist windows (any breath period).
 At the end of the Assist window when no patient efforts are detected.
Spontaneous / Pressure Support breaths may be initiated and /or occur during
support windows between mandatory breaths.
Figure 171: Breath Patterns in SIMV Pressure Control and Volume Control Modes
If a patient’s initiated breath overlaps with the next mandatory breath period, an
Assist window opens, and the ventilator either waits for the next patient effort or
delivers the next mandatory breath at the end of the Breath window.
Mandatory breaths terminate when:
 The set tidal volume is delivered.
 The level of High pressure Alarm is reached.
 The I:E ratio reaches 1.2 :1 when an inspiratory time is not manually set.
PARAMETERS SETTING
The following parameters can be set:
 Mandatory Breath Rate
 O2%
 Mandatory Tidal Volume
 Peak Flow, Adaptive or set value
 I Time, Adaptive or set value
 Limit Pressure
 Triggering type and sensitivity
 Support pressure for pressure support breaths
