Ventilation Modes Operations
5 - 16 046-003777-00 A5/A3™ Operating Instructions
5.6.8.1 To Set PCV Mode
1. Select the PCV tab on the Main Screen.
2. Check that all PCV parameters are set appropriately.
If necessary, select the parameter softkey to edit the parameters settings (see FIGURE 5-13).
You can use the digital keyboard on the screen to enter the desired value, or continuously
press the or buttons to rapidly increase or decrease the parameter values.
3. Select the Set Mode softkey to confirm.
PCV parameters:
• VtG (A5 only): Tidal volume guarantee (mL)
• PlimVG (A5 only): pressure limit level of volume guarantee (cmH
2
O)
• Pinsp: Peak inspiratory airway pressure (cmH
2
O)
• Rate: Breath rate (bpm)
• I:E: Ratio of inspiratory time to expiratory time
NOTE: The screen displays the calculated Tinsp when adjusting the I:E ratio
(software bundle version 02.06.00 and later).
• PEEP: Positive end-expiratory pressure (cmH
2
O)
• Tslope: Rise time (sec)
NOTE: Before activating a new mechanical ventilation mode, ensure that all
related parameters are set appropriately.
5.6.9 Synchronized Intermittent Mandatory Ventilation (SIMV)
The A5 supports two modes of SIMV: SIMV-volume control (SIMV-VC) and SIMV–pressure control
(SIMV-PC). The A3 supports SIMV-VC only.
5.6.9.1 Pressure Support in Synchronized Intermittent Mandatory
Ventilation (SIMV)
In SIMV-VC and SIMV-PC (A5 only) Ventilation modes, PS Ventilation can be turned on and off by
changing the PS setting to On and Off, respectively. When PS Ventilation is Off, the ΔP and Tslope
settings are disabled in SIMV-VC mode, and the ΔP setting is disabled in SIMV-PC mode.
