• Characteristics of flow during inspirium - the user may select among seven defined
flow characteristics in the time of inspirium: progressive, constant, degressive,
sinusoidal, 50% degressive, 50% progressive and modified sinusoidal. Their names
are derived from the shape of the flow curve during inspirium.
Back-up ventilation mode for possible apnoe - Apnoe Back Up ventilation
VEOLAR offers the application of this function in the SIMV, Spont or MMV modes,
but not in the PCV mode of pressure-guided ventilation. Following an apnoe alarm, it
automatically launches the set-up (back-up) artificial lung ventilation. In order for the
ventilator to switch to the back-up ventilation, the so called back up mode must be preset prior
to switching the apparatus on. The back-up ventilation is set up by a switch on the panel with
special functions. The switch can only be used during the first second after switching the
ventilator on. For more information on the back-up mode, see [6.3].
Alarm control panel
The panel for controlling alarms allows for fast detection of the ventilator’s malfunction, it
allows for setting up specific marginal values for the monitored quantities, and is also used in
setting up the back-up mode. You can see a picture of the alarm panel in Fig. 6.5.
