5.5.2 Adjusting Alarm Limits Automatically
The defibrillator/monitor can automatically adjust the patient’s alarm limits according to the measured vital signs. When
[ Auto Limits ] is selected, the equipment automatically calculates alarm limits based on the latest measured parameter
values.
To enable auto alarm limits, press the Main Menu button on the equipment’s front panel, and then select [ Alarm Setup
>> ] [
→
Para. Alarm>> ] [
→
Auto Limits ].
You can also access [ Auto Limits ] by select a parameter window to enter the [ Para. Alarm ] menu.
When auto alarm limits have been applied, you can manually adjust the alarm limits through the Para. Alarm Setup
menu so that they are appropriate for your patient.
The defibrillator/monitor calculates the auto limits based on the following rules.
Low alarm limit High alarm limit
