5.1 Alarm Modes

5.1.1 Alarm Level

Each alarm, either technical or physiological, has its own level. For alarm of higher level, when
the alarm condition is active, the system will give a prompt in various ways. Alarms in the
monitor are divided into three levels: high, medium and low.
High-level alarm indicates the patient's life is in danger or the monitor has serious problem in
technical respect. It is the most serious alarm.
Medium-level alarm means serious warning.
Low-level alarm is a general warning.
Alarms are classified into three categories, which are physiological alarm, technical alarm and
general alarm. Physiological alarms refer to those alarms triggered by patient's physiological
situation which could be considered dangerous to his or her life. Technical alarm refer to system
failure which can make certain monitoring process technically impossible or make monitoring
result unbelievable. Technical alarm is also called System Error Message. General alarm belongs
to those situations that can not be categorized into these two cases but still need to pay attention.
The monitor has pre-set the alarm levels for the parameters.
Alarm level of the System Error Message (technical alarm) is pre-set in the system.
The alarm levels for technical alarms, general alarms and some physiological alarms are pre-set
by the system and cannot be changed by the user in most of the cases. But you can alter the alarm
level for SpO SENSOR OFF. For more information, please refer to SpO SETUP in 4.11
