Dialogue:
Monitor and ventilator feature a dialogue with the user
mediated by:
● keys,
● rotary controls,
● displays and
● beeps.
Basic conditions of the operating state are
established by adjusting the delivery valves
or pressure limitation (e.g. APL valve).
● Keys: For direct command input
● Rotary control:
For selection by ...
... turning
This causes a cursor frame (on the screen)
to be moved or a variable numerical value
(on the display window of the ventilator or
on the screen) to be changed.
... pressing
The value selected with the rotary control
is adopted as a valid parameter or a
process is started or ended.
● Displays: For presenting all information on the
screen and on the display windows of the
ventilator.
● Tone sequences:
As an acoustic supplement to the
messages. They are coupled with certain
sounds or tone sequences, according to
priority classes.
Tone sequences accompanying warnings
are output continuously, every 30 seconds
with caution messages and only once in
conjunction with advisory messages.
These are to draw the user's attention to
the messages which appear simultane-
ously in the displays.
European Standard EN 740 stipulates use
of EN tones.
Alternatively there are tones in keeping
with Dräger conventions available.
