The Pressure Controlled mode is a controlled ntrolled mode is a controlled
breathing mode.

7. Trigg. Flow / Trigg. Pressure
The delivered volume is dependent upon the delivered volume is dependent upon the
pressure above PEEP, lung compliance and EEP, lung compliance and
resistance in the patient tube system and he patient tube system and
airways. This means that the Tidal Volume This means that the Tidal Volume
can vary. Pressure Controlled mode is y. Pressure Controlled mode is
preferred when there is leakage in the when there is leakage in the
breathing system e.g. due to uncuffed ue to uncuffed
