Passport 12/Passport 8 Operator’s Manual 7-7
WARNING
Make sure that the alarm limit settings are appropriate for your patient before monitoring.
Setting alarm limits to extreme values may cause the alarm system to become ineffective. For example, high
oxygen levels may predispose a premature infant to retrolental fibroplasia. If this is a consideration, do NOT
set the high alarm limit to 100%, which is equivalent to switching the alarm off.
When monitoring patients that are not continuously attended by a clinical operator, properly configure the
alarm system and adjust alarm settings as per the patient's condition.
7.5.2 Adjusting Alarm Limits Automatically
The monitor can automatically adjust alarm limits according to the measured 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, 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 [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 guidelines:
