- Inspiratory:expiratory ratio
Flow - Initial flow
Texp - Expiratory time
TrigWnd
- Trigger window
Tplat - Plateau time
MV - Minute volume
Ptrig

Ventilation begins after pressing of the graphic button "Apply" or through 10 s, if it there are no
actions on editing of ventilation parameters.
After pressing of the corresponding "Edit" button ventilation parameters located in the bottom
line of the main screen and parameters of the apnea become available for editing. When venti-
