i. GAS ALARMS. Selecting this menu option will bring up the GAS ALARMS
(Anesthetic Agent Alarm Limits) Menu (See Figure 6-2). All the Alarm Limits
associated with the Anesthetic Agent System are adjusted in this menu. The following
is a description of the GAS ALARMS Menu:
This menu has the following menu options associated with it:
(1) SET INDIVIDUAL. Selecting this menu option allows the operator to adjust
individual Anesthetic Agent Alarm Limits. Once this menu option is selected,
turning the knob will allow the operator to scroll through the individual Agent
Alarm Limits for manual modification. Once the limit to be modified is
highlighted, pressing the knob selects the limit and turning the knob changes
the value. When the desired setting is shown in the window, pressing the knob
again will make the change effective and return to scrolling through the
individual Agent Alarm Limits.
(2) CALCULATE AGENT/O2. Selecting this menu option causes the monitor
to calculate new alarm limit values on all active Agent and O2 settings at once.
The calculations are as described under UPPER WINDOW and LOWER
WINDOW menu options.
(3) UPPER WINDOW. Selecting this menu option selects the percent value used
in calculating the HIGH Alarm Limits with the CALCULATE AGENT/O2
menu option. The menu options are 5%, 10%, 15%, 20% (default), or 30%.
The monitor uses the current value of the parameter and brackets it with the
percentages set by this menu option and the LOWER WINDOW menu option.
