Operator’s Manual of Anesthesia System 6 - 9
Operations Set Ventilation
• I:E or Tinsp: ratio of inspiratory time to expiratory time or time of inspiration
• PEEP: positive end-expiratory pressure
• Tslope: rise time
NOTE: Before activating a new automatic ventilation mode, ensure that all
related parameters are set appropriately.
6.6.6 Set Pressure Control Ventilation - Volume Guarantee (PCV-VG)
Pressure Control Ventilation - Volume Guarantee (PCV-VG) mode implements volume-guaranteed
ventilation in a pressure-controlled manner. In this mode, the pressure level should be kept as low as
possible during the inspiratory phase, meanwhile the gas supply volume should be equal to the
preset tidal volume. The Pressure control level will vary according to the tidal volume setting,
resistance and compliance of the patient’s lungs.
Figure 6-5 Pressure Control Ventilation - Volume Guarantee (PCV-VG) Tab
Set PCV-VG Mode:
1. Select the PCV-VG tab on the Main Screen.
2. Select the parameter soft key and assign an appropriate value on the pop-up screen.
3. Check that all PCV-VG parameters are set appropriately.
4. Select the [Set Mode] soft key to confirm the settings.
PCV -VG parameters:
•Vt: tidal volume
• Plimit: pressure limit level with volume guarantee
•RR: respiratory rate
• I:E or Tinsp: ratio of inspiratory time to expiratory time or time of inspiration
• PEEP: positive end-expiratory pressure
• Tslope: rise time
NOTE: Before activating a new automatic ventilation mode, ensure that all
related parameters are set appropriately.
6.6.7 Synchronized Intermittent Mandatory Ventilation (SIMV)
The equipment supports three modes of SIMV: SIMV-volume control (SIMV-VC), SIMV–pressure
control (SIMV-PC) and SIMV–volume guarantee (SIMV-VG).
