7.5.2 Adjusting Alarm Limits Automatically
The monitor can automatically adjust alarm limits according to the measured vital signs,
using the auto limits function. When auto limits are selected, the monitor calculates safe
auto limits based on the latest measured values.
To get accurate auto alarm limits, you need to collect a set of measured vital signs as a
baseline. Then, in the main menu, select [ Alarm Setup >> ][ Parameters ][ Auto Limits ]
[ Ok ]. The monitor will create new alarm limits based on the measured values.
Before applying these automatically created alarm limits, confirm if they are appropriate for
your patient in the mass alarm setup menu. 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 the auto limits based on the following rules.
