The default settings for fresh-gas delivery, ventila-
tion, and alarms are loaded in the Standby screen
and can be modified in the standard configuration if

Entering the patient's age
The set age influences the calculation of the MAC
value, the volumeter scale, the V-axis of the loops
and ventilation monitoring, as well as the alarm lim-
its for SpO
and the automatic volume adjustment of the
Breathing Sound Emulator (BSE) module during
operation.
In addition, the trigger sensitivities and software al-
gorithms for suppressing artifacts are also modi-
fied, thus influencing the quality of ventilation in
modes supporting spontaneous breathing.
1 Press the soft key age (B).
2 Set and confirm the age using the rotary knob.
The patient age parameter is available in the
Standby screen as well as in all ventilation modes.
Changing the patient's age during operation imme-
diately influences the parameters described above.
Entering the patient's ideal body weight
(optional)
The patient's ideal body weight describes that pro-
portion of the body relevant to setting the ventilation
parameters (the patient's body weight minus the
assumed excess fat).
The set ideal body weight influences the ventilator
default settings for tidal volume V
Freq. as well as the alarm limits for the expiratory
minute volume MV during operation.
