Operator’s Manual of Anesthesia System 6 - 21
Operations Stop Automatic Ventilation
To start automatic ventilation from Standby mode:
1. Set the Auto/Manual switch to the Manual position.
2. Exit Standby by touching the Main Screen or by turning on the fresh gas.
3. Set the Auto/Manual Switch to the Auto position.The system will start automatic ventilation.
6.9 Stop Automatic Ventilation
To stop automatic ventilation:
1. Ensure that the breathing system is set up and the APL valve is set properly before stopping
automatic ventilation.
2. Set the Auto/Manual switch to the Manual position.This selects manual ventilation and stops
automatic ventilation.
6.10 Relationships of Ventilation Parameters
Different ventilation modes may share the same ventilation parameters and values. For example,
SIMV-VC and VCV both include Vt, Plimit, RR, Tpause, and PEEP. Therefore, these parameter values that
are linked may be passed from the previous ventilation mode to the current mode."Ventilation
Linkage Parameters" on Pages B-10 includes a table that lists how the linked parameter values are set
when ventilation modes are changed.
Ventilation parameter values that are linked are set according to relationship equations. "Constraints
Among Ventilation Parameters" on Pages B-14 includes a table of equations to show how linked
parameter values are set when ventilation modes are changed.
