Use the Start Case menu to set the case data and start the case.
A case can be started using default settings or using custom
settings. The default settings are configured by the Super User. See
the "Super user mode" section for information on the Start Case
menu defaults.
Default Settings selection shows the first of five default case types
when the Start Case menu is accessed. Four of the default case
types are configured by the Super User. The fifth default case is Last
Case.
The Ideal Weight, Age, and Volume Apnea Alarm values are set to
the pre-selected settings defined by the Super User corresponding to
the case type.
Make sure that the patient breathing circuit is correctly
assembled and that the ventilator settings are clinically
appropriate before starting ventilation. Incorrect breathing
circuit assembly and incorrect ventilator settings can
injure the patient.
• Make sure that the preset alarm limits are appropriate for
the patient before starting ventilation. Incorrect alarm
settings can injure the patient.

this setting for breath rate and tidal volume calculations based on the
set patient weight.
The Minimum Alveolar Concentration (MAC) concept is based on the
assumption that in a steady state condition, the alveolar partial
pressure of a gas is equal to the partial pressure in the effector organ
of the central nervous system. MAC values are used to estimate the
level of anesthesia caused by volatile anesthetics. The MAC value
display range is 0.0 to 9.9.
