About Automatic Alarm Limits (AutoLimits)
The monitor can automatically set alarm limits suited to your individual patient, using the Automatic
Alarm Limits function. This tells the monitor to adapt the alarm limits of selected measurements to the
measured vital signs within a defined safe limit. The monitor calculates safe AutoLimits for each
patient based on the measured values from the last 12 seconds.
The wide and narrow limits have a fixed relationship to the measured value within the non-
pathological range. Outside of this range, no auto limits are calculated. To set values outside of the
non-pathological range, limits must be changed manually, based on the clinician's judgement about the
Limits Narrow sets limits close to the currently measured values for situations where it is critical
for you to be informed about small changes in your patient's vital signs.
Limits Wide sets limits further away from the currently measured values for situations where small
changes are not so critical.
Use the keys in the Change Limits window to apply AutoLimits for individual measurements.
These keys are not available if AutoLimits have been disabled for the measurement in the monitor's
AutoLimits are not available for all measurements. The list of measurements for which AutoLimits can
be used is defined in the monitor's Configuration mode.
Use the Change Limits window to check AutoLimits before you apply them to ensure that they are
appropriate for your individual patient and their clinical condition. Once applied, AutoLimits are
shown on the monitor screen just like manually-set alarm limits. If the AutoLimits are not appropriate
for your patient, you must set alarm limits manually. The limits remain unchanged until you set them
again or change them manually.
