CPAP low:
this alarm monitors the lower threshold of the CPAP pressure. If this value is undershot by the CPAP
average value for a certain amount of time, a
CPAP pressure low
alarm is triggered after a delay (see chapter
Please note:
Because of the
scale,
it is possible that the
CPAP high
and
CPAP low
alarm thresholds (generally shown as
dashed lines) are not visible on the display (e.g. if the scale is set from 0 to 10 and the value for
CPAP high
is
13). In this case, the value of the limit is visible as a number to the upper right next to the graph.
FiO
2
:
the FiO
2
setting determines the alarm interval of the oxygen alarm. The thresholds of this alarm depend
on the target oxygen concentration selected and are displayed next to the target oxygen levels. If this value
(see chapter 8.2) is exceeded/undershot, an alarm will be triggered after a delay. There are two different
setting options for this alarm, which must be preset in the service menu by a service technician.
-
Automatic FiO
2
alarm
: Here the FiO
2
limit values are automatically adapted to the new target
value for any change in the target oxygen concentration.
-
Manual FiO
2
alarm
: In this case, if there are changes to the target oxygen concentration, the FiO
2
alarm threshold values are not changed. This adaptation can only be performed manually by the
user by opening the
Alarm setting
menu, selecting the button
FiO
2
alarm refresh
and confirming
this by pressing the dial. If adapting the alarm thresholds is not possible because they already
refer to the currently set oxygen concentration, the button
FiO
2
alarm refresh
is dimmed and
instead, the button to change the alarm interval will be visible.
Push alarm:
The push alarm setting can be used to determine how the medinCNO
®
informs the user in the
event of a triggered push. The following settings are available: information via an acoustic signal and an optical
signal, information via an optical signal alone or no information. In addition, there is an option to use a sound
and light signal to indicate pushes caused only by apnoea. When backup is activated, the push alarm cannot
be turned off; rather it is at least indicated by a visual signal.
Alarm Silent:
The Alarm Silent function can deactivate the acoustic alarm for five minutes. After this time, the
acoustic alarm reactivates itself without any intervention by the user. If the medinCNO
®
sound was deactivated
for five minutes, the sound can be reactivated with this button before the five minutes are up.
Warning:
This setting may only be used while the medinCNO
®
is not connected to a patient (e.g. when replacing individual
components of the CPAP system) and the operator must remain by the device all the time that the alarm is off.
Brightness:
The brightness setting changes the brightness of the backlighting of the display.
Scale:
Using this setting, the scale of the pressure graphs can be changed. The scales 0-10 mbar/cmH
2
O, 0-15
mbar/cmH
2
O or 0-20 mbar/cmH
2
O are available.
Please note:
The value for the CPAP pressure high alarm (red) is 18 mbar. Even if the scale up to 20 mbar is used, the value
is still 18 mbar.
Sound:
The user can determine the repetition frequency of the alarm sounds by altering the sound setting. If
+5 is set here, the alarm sounds of the medinCNO
®
will be repeated very frequently. This setting is suitable for
environments with many devices and a significant amount of background noise, since it facilitates the
