Alarm
5.1
Alarm Type
The monitor can give an alarm of three types: physiological alarm, technical alarm and prompt message.
(1)
Physiological alarm
Physiological alarm is usually caused by a certain physiological parameter of the patient which
exceeds the set upper/lower limit scope or by the physiological abnormality of the patient. The alarm
message of the physiological alarm will appear in the physiological alarm area above the screen.
(2)
Technical alarm
The technical alarm is also referred to as a system error message, indicating the alarm is caused by a
misoperation or system malfunction thereby causing improper operation of a system function or
distortion of monitored results. The alarm message of the technical alarm will appear in the technical
alarm area above the screen.
(3)
Prompt message
Strictly speaking, prompt message does not belong to the domain of alarm. It is to display the
information relative to the system conditions themselves, which have nothing to do with the patient‘s
vital sign.Prompt message will appear in the prompt message area.
5.2
Alarm Level
The monitor can give an alarm in three volume levels: high, medium and low, based on the severity.
(1)
High level alarm:
The patient is in a critical condition, endangering the patient‘s life, emergent attention required.
(2)
Medium level alarm:
The patient‘s vital signs are abnormal, relevant measures and treatment are immediately required.
(3)
Low level alarm :
The patient‘s vital signs are abnormal,and relevant measures and treatment may be required.
All alarm levels for technical alarms and some physiological alarms have be set before the monitors
