SIMV-VC: Synchronous Intermittent Mandatory Ventilation- Volume Control

Similar to SIMV-PC, but with volume control.

Setting Name
Description
Tidal Volume
Target gas volume that the device delivers during a spontaneous breath
Pressure Support Target pressure that the device delivers during the inspiratory phase of a spontaneous breath
PEEP
PEEP
Positive end expiratory pressure
Positive pressure maintained in the patient circuit during exhalation: must be less than or equal to the
pressure setting.
Inspiratory Time
For a mandatory breath, length of the inspiratory phase
Rise Time
Time required for the ventilator to change from the expiratory pressure setting to the inspiratory
pressure setting when the breath is triggered.
Breath Rate
Minimum rate of mandatory breaths per minute
Flow Pattern
Sets the flow-pressure waveform
Trigger Type
•
Auto-Trak
•
Sensitive Auto-Trak (passive circuits only)
•
Flow Trigger (Passive, Active PAP, Active Flow, or Dual Limb circuits)
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.
Flow Cycle
Sensitivity
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.

Therapy Features
The following features are available in addition to the therapy modes.
Backup Ventilation Enable
D
ESCRIPTION
Set the device to deliver ventilator-initiated breaths when patient-initiated breaths are not detected, based on the Apnea alarm interval. When you
turn Backup Ventilation on, set an Apnea interval in the alarm settings tab. Within the apnea interval; if no breaths are triggered by the patient, the
ventilator delivers breaths at the set pressure or volume based on the Backup Rate. When an Apnea alarm occurs, the ventilator automatically
starts backup ventilation. When two consecutive patient-initiated breaths are detected, the ventilator automatically reverts to patient-initiated
breaths.

Backup ventilation settings take precedence over standard therapy mode settings.
