5 Alarms

Alarms, triggered by a vital sign that appears abnormal or by technical problems of the

pulse oximeter, are presented to the user by visual and audible alarm indications.

5.1 Alarm Categories

By nature, the pulse oximeter’s alarms can be classified into three categories:

physiological alarms, technical alarms and prompt messages.

1. Physiological alarms

Physiological alarms, also called patient status alarms, are triggered by a monitored

parameter value that violates set alarm limits or an abnormal patient condition.

Physiological alarm messages are displayed in the physiological alarm area.

2. Technical alarms

Technical alarms, also called system status alarms, are triggered by a device

malfunction or a patient data distortion due to improper operation or system

problems. Technical alarm messages are displayed in the technical alarm area.

3. Prompt messages

As a matter of fact, prompt messages are not alarm messages. Apart from the

physiological and technical alarm messages, the pulse oximeter will show some

messages telling the system status. Prompt messages are displayed in the technical

alarm area.

5-1

5.2 Alarm Levels

By severity, the pulse oximeter’s physiological alarms can be classified into three

categories: high level alarms, medium level alarms and low level alarms.

1. High level alarms

Indicate that the patient is in a life threatening situation and an emergency

treatment is demanded.

2. Medium level alarms

Indicate that the patient’s vital signs appear abnormal and an immediate treatment

is required.

3. Low level alarms

Indicate that the patient’s vital signs appear abnormal and an immediate treatment

may be required.

The pulse oximeter’s technical alarms can be classified into three categories: high level

alarms, medium level alarms and low level alarms.

The levels for some technical alarms and physiological alarms are predefined before the

pulse oximeter leaves the factory and cannot be changed.

5-2

5.3 Alarm Indicators

When an alarm occurs, the pulse oximeter will indicate it through the following

indications:

 Alarm lamp
 Alarm tone
 Alarm message

For different alarm levels, the alarm lamp, alarm tone and alarm messages presented are

different.

5.3.1 Alarm Lamp

If a technical or a physiological alarm occurs, the alarm lamp will flash. The flashing

color and frequency match the alarm level as follows:

 High level alarms: the lamp quickly flashes red.
 Medium level alarms the lamp slowly flashes yellow.
 Low level alarms: the lamp turns yellow without flashing.

5.3.2 Alarm Tones

When a technical or a physiological alarm occurs, the pulse oximeter presents different

alarm tone patterns to match the alarm level:

 High level alarms: triple + double + triple + double beep
 Medium level alarms: triple beep.
 Low level alarms: single beep.

5-3

5.3.3 Alarm Messages

When an alarm occurs, an alarm message will appear in the technical or physiological

alarm area.

For physiological alarms, the asterisk symbols (*) before the alarm message match the

alarm level as follows:

 High level alarms: ***
 Medium level alarms: **
 Low level alarms: *

Additionally, the system uses different background colors for the alarm message to

match the alarm level:

 High level alarms: red
 Medium level alarms: yellow
 Low level alarms: yellow

NOTE

z When multiple alarms of different levels occur simultaneously, the pulse

oximeter will select the alarm of the highest level and give visual and
audible alarm indications accordingly. Alarm messages will be presented
circularly.

5.3.4 Alarm Status Symbols

Apart from the aforementioned alarm indicators, the pulse oximeter still uses the

following symbols telling the alarm status:

indicates the alarm sound is paused.



indicates the alarm sound is turned off.



lamp remains lit and alarm message remains presented. The audible alarm is reactivated

automatically when:

 The pulse oximeter is shut down and restarted;
 The factory configuration is loaded;
 The user configuration is loaded.

When a factory or user configuration is selected, the alarm volume of the pulse oximeter

may be lower than the minimum alarm volume. In this case, the alarm volume is

automatically adjusted according to the minimum alarm volume.

WARNING

z When the alarm sound is switched off, the pulse oximeter will give no

audible alarm tones even if a new alarm occurs. Therefore the user
should be very careful about whether to switch off the alarm sound or
not.

8.5 Checking the Lithium Ion Battery

The performance of a rechargeable lithium ion battery may deteriorate over time. To

check the performance of a battery, follow this procedure:

1. Disconnect the pulse oximeter from the patient and stop all monitoring and

measuring procedures.

2. Place the pulse oximeter in the Charger stand and connect the AC mains. Allow the

battery to be charged uninterruptedly for above 2 hours.

3. Disconnect AC mains and allow the pulse oximeter to run on the battery until it

shuts off.

The operating time of a battery reflects its performance directly. If the operating time of

a lithium ion battery is noticeably shorter than that stated in the specifications, replace it

or contact your service personnel.

NOTE

z Life expectancy of a lithium ion battery depends on how frequent and

how long it is used. For a properly maintained and stored lithium ion
battery, its life expectancy is about 3 years. For more aggressive use
models, life expectancy can be less. We recommend replacing a lithium
ion battery every 3 years.
