6.7.2 Initiating Auto Alarm Limits
The TM80/TM70 provides the auto alarm limits function to automatically adjust alarm
limits according to the patient’s vital signs used. When auto limits are selected, the
TM80/TM70 calculates safe auto limits based on the latest measured values. To get accu-
rate auto alarm limits, you need to collect a set of measured vital signs as a baseline.
To initiate auto alarm limits, follow this procedure:
1. Press the key to enter the main menu.
2. Tap [Alarms].
3. Tap [Alarm Limits]. The [Alarm Limits] menu is displayed.
4. Tap [Auto Limits].
5. In the dialog that pops up, tap [OK].
Then the TM80/TM70 will automatically calculate alarm limits based on the latest mea-
sured values. Before applying these automatically created alarm limits, confirm if they
are appropriate for your patient from the Limits menu. If not, you can adjust them manu-
ally. These alarm limits will remain unchanged until you select auto limits again or adjust
them manually.
The TM80/TM70 calculates auto limits basing on the following rules:
NOTE
When the TM80/TM70 is connected to the CMS, any changes to the alarm
properties at the TM80/TM70 or the CMS will be communicated to the
other side to make sure that the alarm settings are consistent.
