Chapter 6 Alarm
This chapter gives general information about the alarm and corresponding remedies.
Note: The equipment generates all the auditory and visual alarms through
speaker, LED and screen.
6.1 Alarm Priority
There are two kinds of alarms, defined as physiological alarm and technical alarm.
Physiological alarms refer to those alarms triggered by patient’s physiological situation
which could be considered dangerous to his or her life, such as SpO
2
exceeding alarm
limit (parameter alarms). Technical alarms refer to system failure, which can make certain
monitoring process technically impossible or make monitoring result unbelievable.
General alarm belongs to those situations that cannot be categorized into these two cases
but still need to pay some attention. Each alarm, either technical or physiological, has it’s
own priority.
Alarms in the monitor are divided into three priorities, that is: high priority, medium
priority and low priority.
High priority alarm indicates the patient’s life is in danger. It is the most serious alarm.
Medium priority alarm means serious warning.
Low priority alarm is a general warning.
Only alarm priority of parameters exceeding limits alarm can be modified by the user,
the other alarm priorities of physiological and technical alarms are preset by the system
and they can not be changed by the user.
6.2 Alarm Modes
When alarm occurs, the monitor may raise the user’s attention in two ways, which are
auditory prompt, visual prompt and description. Visual prompt is given by alarm
indicating lamp and screen of the monitor, auditory prompt is given by speaker in the
device. Physiological alarm information is displayed in the Physiological Alarm area.
Most of technical alarm information is displayed in the Technical Alarm area. Technical
alarms related to NIBP measurement are displayed in the NIBP parameter area.
The Physiological Alarm area is on the upmost right part of the screen. The Technical
Alarm area is to the left side of the Physiological Alarm area.
The alarm sound and visual display comply with clause 201.3.2 of the standard IEC
601-1-8.
