Select night mode
If you press the dial during therapy, you will activate night mode. The display then goes
dark so that only the bar chart with the pressure display is visible. Therapy continues as nor-
mal. The display switches back on if you press the dial again or any other key. The display
switches back on automatically if an alarm situation arises.
5.2 Start up the device
5.2.1
Operating states
Three operating states are possible on the therapy device: on, off and standby.
If the device is switched on, therapy is in progress.
In standby, the blower is switched off, but the device is immediately operational with a
brief press of the On/Off key as long as the patient circuit is connected correctly. Settings
can be made on the device in standby mode.
If the device is switched off completely, the blower and the display are likewise switched
off and no settings can be made on the device.
Note
On standby, the display switches off if it is not used for 5 minutes (applies only in
patient mode).
5.2.2
Starting up
1. Connect the device to the power supply with the aid of the power cord. The standby
screen appears in the display after about 5 seconds.
2. First, perform a function check (see “7. Function check” on page 74).
3. Connect the patient circuit to the patient/ventilator
interface. It is essential to follow the relevant
instructions for use for the patient/ventilator interface,
the patient circuit and, if appropriate, the exhalation
system.
Caution!
Always use a separate exhalation system for
leakage ventilation (e.g. Silentflow leakage
ventilation), otherwise the CO
2
concentration
would rise to critical values in the patient/
ventilator interface and tube and thus obstruct
the patient's breathing.
