10.11 How to Set an Alarm Threshold
To adjust an alarm
threshold press the
Adjust button in the
alarm panel.
If no alarm condition is
present the user will
have to select the
alarm threshold for
modification.
In an alarm condition
the user on pressing
the Adjust button will find that the crossed alarm
threshold will automatically be selected. (The alarm
threshold will flash).
In the Mode Select
panel a new panel
appears giving a
description on how to
set the alarm
thresholds, this panel
indicates that the
alarm thresholds can
be modified. The
alarm thresholds
remain adjustable for
5 seconds after the last adjustment, after that the
user needs to re-activate them again by pressing
the Adjust button.
The alarm threshold can be selected by touching in
the alarm threshold adjustment column or the text
and numerical value in the waveform window. The
adjustment column is an area above or below an
active alarm threshold text. The diagram below
details the columns present in the pressure
waveform window.
Note: When using the ventilator without a
flow sensor the following thresholds are not
present, High & Low Tidal Volume, High &
Low Minute Volume and the breath detection.
High Minute Volume
Low Minute Volume
Note: The dotted lines do not appear in the
actual waveform window. They are for
graphical purposes only.
