Loading default settings
The default settings for gas metering,
ventilation and alarms are loaded in the
standby screen and can be modified in
the standard configuration if necessary.
These default settings are valid
whenever Primus is switched on. They
can be changed and set as required for
the specific hospital concerned, see
"Configuring the default settings" on
page 106.
1 Press the soft key »restore default
settings« and press the rotary knob
to confirm.
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 limits for
SpO2 measurement (optional) during
operation. In addition, the trigger
sensitivities and software algorithms for
suppressing artefacts are also modified,
thus influencing the quality of ventilation
in modes supporting spontaneous
breathing.
2 Press the soft key »age«.
@ Set and confirm the age using the
rotary knob.
Entering the patient's ideal
body weight (optional)
The patient's ideal body weight
describes that proportion of body mass
of relevance for 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 VT and frequency Freq. as well
as the alarm limits for the expiratory
minute volume MV during operation.
