8.4 Vent status
The Vent Status panel (Figure 8-7) depicts six separate parame-
ters related to the patient’s ventilator dependency, including
oxygenation, CO
2
elimination, and patient activity.
A floating indicator moving up and down within the column
shows the value for a specific parameter. When the indicator is
in the light blue (weaning) zone, a timer starts, showing how
long that value has been in the weaning zone. When all values
are in the weaning zone, the frame around the Vent Status
panel changes to green. This color change indicates the patient
could be ready for discontinuation of ventilation. The panel is
updated breath by breath.
This section describes the parameters shown in the Vent Status
panel. Oxygen, PEEP, ExpMinVol, and Pinsp values are always
shown, but in Configuration mode you can configure the
remaining two parameters from these choices: RSB, VariIndex
1
(variability index), P0.1, and %fSpont.
When Quick Wean is enabled, the Vent Status panel changes
to show
Time to Start SBT
, and SBT running information
when a spontaneous breathing trial is underway. For details on
Quick Wean, SBTs, and the Vent Status panel in this mode, see
the Quick Wean chapter in the INTELLiVENT

-ASV manual.
1. The variability index (VariIndex) parameter is not available in the USA
