5.2.1 Patient category
The selected patient category is either 'Infant'
or 'Adult'. This determines the allowable
setting ranges for ventilatory parameters and
patient data.
Recommended ventilatory parameters outside
the allowed patient category range are always
highlighted in yellow.
If the patient category is changed in standby,
all entered patient data except age is removed.
Patient age has the default setting.
Recommended ventilation parameters are also
removed.
If the patient category is changed during
running mode, entered patient data is
generally conserved but patient details outside
the allowed patient category range are
automatically changed to the closest allowable
value.
If patient data is changed while the system is
in AUTO running mode, it will not be possible
to select and use the resulting 'recommended
values'.
Changing the patient category can also be
done by using options available under the
Menu membrane button, see Chapter 9, page
165.
Changing the patient category affects the
following:
• Alarm ranges and defaults
• Circuit compliance compensation
• Parameter setting ranges
• Step values, i.e. differences in increments
when increasing/decreasing parameter
values
• Automatic changes in parameter settings
when the current value is outside the patient
category parameter range
If there is no circuit compliance compensation
data available after the patient category has
been changed, the default value will be used
until a full check, or leakage check, has been
performed.
CAUTION: Alarm limits and ventilation
settings may change after having selected
a different patient category. Re-check the
set alarm limits after the patient category
has been changed.
