Description:
In DualPAP, the ventilator works at two
pressure levels adjusted by the operator,
Pr Superior and Pr Inferior.
The change to the lower level of pressure
occurs at the end of Superior T (given
time to the higher level of pressure).
Similarly, the restoration of the higher
pressure level so happens that is
exhausted Low T (time for the level of
the lower pressure).
Consequently, the respiratory rate and
I:E ratio are directly related to this
alternation between levels.
DualPAP allows spontaneous cycles in
both pressure levels and includes
synchronization of possibility with the
inspiratory effort of the patient.
When there are no spontaneous
breathing, DualPAP is similar to pressure
control mode, differing from the latter
because the adjusting time (T Upper and
Lower T), rather than the respiratory
rate.
