Pressure-controlled ventilation
The upper pressure level is determined by Pinsp.
The duration of the mandatory breaths is deter-
mined by Ti. As in all pressure-controlled ventilation
modes, the tidal volume supplied depends on the
difference in pressure "Pinsp – PEEP", the lung
mechanics (resistance and compliance) and the
patient's respiratory drive. The pressure rise from
the lower pressure level PEEP to the upper pres-
sure level Pinsp is determined by the Slope or In-
sp. flow setting. The start setting can be configured
on the page System setup > Ventilation > Start

Assisted-controlled ventilation
Every inspiratory effort of the patient on PEEP level
triggers a synchronized mandatory breath. Thus,
the time and number of mandatory breaths are de-
termined by the patient. The trigger window covers
the expiratory time minus a refractory period for the

mined by the respiratory rate RR and the inspirato-

triggered at the latest at the end of the expiratory
time (backup respiratory rate).
The minimal number of mandatory breaths is deter-
mined by the respiratory rate RR.
