6.6.4 Initiating Auto Alarm Limits
The monitor provides the auto alarm limits function to automatically adjust alarm limits according to the
patient’s vital signs. When auto limits are selected, the monitor calculates safe auto limits based on the latest
measured values. To get accurate auto alarm limits, collect a set of measured vital signs as a baseline.
To initiate auto alarm limits, follow this procedure:
1. Select the Main Menu quick key → from the Alarm column select Limits.
2. From the Limits page, select Auto Limits at the left bottom.
3. Select OK from the popup dialog box.
Then the monitor will automatically calculate alarm limits based on the latest measured values. Before applying
these automatically created alarm limits, confirm if they are appropriate for the patient from the Limits dialog. If
not, you can adjust them manually. These alarm limits will remain unchanged until you select auto limits again
or adjust them manually.
The monitor calculates auto limits based on the following rules:
