Rise Time

The Rise Time setting controls the speed of the pressure/volume increase from start of
inspiration to set inspiratory pressure/tidal volume.
A low setting will give a faster pressure/volume increase and therefore a longer plateau at
the set inspiratory pressure/tidal volume. A high setting will give a slow increase and there-
fore a shorter plateau.
In the VCV-SIMV mode, two different Rise Time settings are made, one for mandatory ven-
tilator-controlled breaths and one for additional pressure support breaths triggered by the
patient.

Insp. Trigger (Inspiratory Trigger)

The inspiratory trigger defines the patient's effort required to initiate a ventilator assisted
breath. When the patient starts a breath, an increasing flow is created in the patient circuit.
If the patient's effort reaches the set inspiratory trigger level an inspiration is initiated.
If the patient cannot trigger a breath, the ventilator will deliver breaths according to the set
Backup Rate, Breath Rate or SIMV Rate.

Sigh % sets the increased % of the set pressure (pressure mode) or volume

In pressure control mode (PCV) and pressure support mode (PSV), the
rise time is set in steps.

In the Volume Control mode (VCV), the rise time for the support is set as
a percentage of the inspiratory time.
If using the VCV-SIMV mode, the percentage settings controls the rise
time for the mandatory breaths triggered by the ventilator. You can also
use step settings as described above, for controlling the rise time for the
support breath, triggered by the patient.
