4. Select【SETTINGS】→【ADVANCED】→【GENERAL】→【ALARM】→【Nurse Call trigger mode】 to set the
trigger mode to be 【continual】or【1s pause】.
Warning: The Nurse Call function should not be used as the primary means of patient monitoring. The
care team should evaluate alarms in combination with observations of the patient’s symptoms and overall
physiological condition.
6. Alarms
Alarms are prompts given by the monitor for medical personnel through visual, audible, and other means when either
a vital sign appears to be abnormal or a technical problem occurs.
Note:
• The monitor generates all audible and visual alarms through a speaker, LED lights and the display. When the
monitor powers on, the alarm LEDs will light once and the speaker will beep, which indicates that the alarm
system is working properly.
• Alarm settings are saved in real time. Once a setting is finished, it is saved simultaneously. After a loss of
power, the alarm settings prior to the power loss will recover automatically when the monitor is restarted.
Warning: Do not set the alarm limits to extreme values that can render the alarm system useless. Vital signs
alarm limits are pre-set by the manufacturer, but be sure to choose clinically appropriate limits for the patient.
When the selected patient ’s type is different from the last one, the alarm limits will return to factory defaults.
6.1 Alarm Categories
The monitor’s alarms can be classified into three categories: physiologic alarms, technical alarms, and prompt
messages.
Physiologic alarms: Physiologic alarms are triggered by a monitored parameter value (i.e., the DIA blood pressure
value) that violates set alarm limits. Physiologic alarm messages are displayed in the physiologic alarm area.
Technical alarms: Technical alarms are triggered by a device malfunction due to improper operation or system
problems. The problems may result in abnormal system operation. Technical alarm messages are displayed in the
technical alarm area.
Prompt messages: Prompt messages are not alarm messages. Prompt messages on the monitor are shown to
indicate the system status.
