4.2.5 Setting the Warning Limits for the External Temperature
WARNING!
n
Incorrect or unused warning limits pose a risk of dangerous situations not
being recognized, thereby endangering the patient.
n
Do not set any extreme warning limits which could make the function of the
alarm system ineffective.
n
When the alarm limits are deactivated, pay special attention to the parameter
values on the touchscreen and the external patient temperature monitoring.
WARNING!
n If the same or similar alarm signals are used on different devices in the same
environment (e.g., in the cardiac operating room), there is a risk that the user
may misinterpret a signal.
n Before beginning the application, ensure that the warning limits used are
suitable and safe for the patient and the current situation.
The warning limits enable you to define when the HCU 40 triggers physiological
alarms in order to detect and react to dangerous situations.
You can set the warning limits for the monitoring of the external temperature
sensors. If the measured value is outside of the alarm limits, the HCU 40
generates an alarm. The alarm ends as soon as the measured value is within the
warning limits again.
You can deactivate warning and alarm limits. The deactivated limit is not
monitored and does not generate an alarm.
