Alarm category
The monitor has two different types of alarms: physiological alarms and technical alarms.
■ Physiological alarms are triggered by patient measurements that exceed parameter limits or patient conditions that are abnormal.
■ Technical alarms are triggered by failure of electrical, mechanical or other monitors, or failure of sensors or components. A technical alarm condition may also result when the algorithm is unable to classify or interpret the available data. In addition to physiological and technical alarms, information can be prompted to inform the status of the system or the status of the patient.
Adjusting the Alarm Light Brightness
NOTE:
If you set alarm light brightness to Auto, the monitor automatically adjusts the alarm light brightness according to the ambient light. The stronger
the ambient light is, the brighter the alarm light is.
