Start a case
Use the Start Case menu to set the case data and to start the gas
flow.
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.
Volume Apnea Alarm is not shown on the Start Case menu when
the Volume Apnea Selection is set to Disable in the Super User
settings.
The TV for Ideal Body Weight menu item from the Patient
Demographics menu can only be accessed when the ventilation
mode is set to VCV, PCV-VG, SIMV VCV, and SIMV PCV-VG. Use
this setting for breath rate and tidal volume calculations based on the
set patient weight.
Minimum Alveolar Concentration
The adjusted Minimum Alveolar Concentration (MAC) is calculated
based on the patient age entered in the Start Case menu or the
Patient Demographics menu. The default patient age of the
selected case type is used if no patient age value is entered.
The MAC value is calculated from the exhaled gas concentration and
the related affects based on the age of the patient. Typically,
younger patients have better liver function and can clear a drug
faster, resulting in a higher MAC value. The MAC calculation used is
based on the Eger formula. When two agents are detected, the MAC
values of each agent are added together. The MAC value range is
0.0 to 9.9.
