User's Manual

6-2
This menu has the following menu options associated with it:
a. SET INDIVIDUAL. Selecting this menu option allows the operator to adjust
individual Alarm Limits. Once this menu option is selected, turning the knob will
allow the operator to scroll through the individual HIGH and LOW 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 HIGH and LOW Alarm Limits.
b. CALCULATE ALL. Selecting this menu option causes the monitor to calculate new
alarm limit values on all active parameters at once. The calculations are as described
under UPPER WINDOW and LOWER WINDOW menu options.
c. UPPER WINDOW. Selecting this menu option selects the percent value used in
calculating the HIGH Alarm Limits with the CALCULATE ALL 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.
(1) For example, if the patient's heart rate is 60, and both percentages have been set
to 10%, activating CALCULATE ALL menu option will set the LOW Alarm
Limit to 54 and the HIGH to 66 (plus and minus 10 percent of the current heart
rate). Corresponding calculations would be used on each of the other active
patient parameters to set their LOW and HIGH values.
(2) The following exception applies:
• If the value being monitored from the patient is so high or low that
it would exceed the range of 3160 MRI Physiological Monitoring
System Alarm Limits (see below), the LOW or HIGH value is set to
the highest or lowest Alarm Limit for that parameter.
d. LOWER WINDOW. Selecting this menu option selects the percent value that is used
in calculating the LOW Alarm Limits with the CALCULATE ALL 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 UPPER WINDOW menu option.
(1) For example, if the patient's heart rate is 60, and both percentage have been set
to 10%, activating CALCULATE ALL would set the LOW Alarm Limit to 54
and the HIGH to 66 (plus and minus 10 percent of the current heart rate).
Corresponding calculations would be used on each of the other active patient
parameters to set their LOW and HIGH values.
The following exceptions apply:
• If the value being monitored from the patient is so high or low that
it would exceed the range of 3160 MRI Physiological Monitoring
System Alarm Limits (see below), the LOW or HIGH value is set to
the highest or lowest Alarm Limit for that parameter.
e. ALARM SOUND. Selecting this menu option will turn the alarm sound on/off. When
turned off, an “X” appears in the bell symbol on the screen and the bell symbol in the
menu indicating that the alarm sound has been disabled. This menu option is identical
to, and interactive with, the ALARMS menu option in the SOUND ADJUST Menu.
f. DEFAULT LIMITS. Selecting this menu option causes the monitor to automatically
set the LOW and HIGH Alarm Limits for all parameters at once based on the system
defaults (See Default Limits in Appendix A or Table 6-1 for a listing of the System
Default Values).
