4.1.3.1. Message System Overview

The 3880 is equipped with a message area which automatically prioritizes and sorts messages

in order of priority. When a message is present, it will show up in the lower left hand corner of

the screen. Messages related to vital signs are color coded to priority and typically use a prefix

denoting the associated vital sign before the message so the operators can quickly understand

the context. The messages prefixes are as follows:

• ECG : Electrocardiogram and HR related messages

• SpO

: Pulse Oximetry related messages

• CO

: Capnography, Gas and respiration related messages

• Gas: Anesthetic agent related messages

• NIBP: Non-Invasive blood pressure related messages

• Temp: Temperature related messages

4.1.3.2. Multiple messages

If there is an unacknowledged message displayed in the bottom left side of the screen when a

subsequent message is generated the messages will stack vertically on top of each other. A

maximum of 10 messages can be displayed at a time. Messages are arranged by priority, with

higher priority messages on top as illustrated 4.1.3.

4.1.3.3. Message Priority

Messages are color coded to quickly alert the operator to the priority of the alarm. The colors

used for messages are as follows:

• Red - High Priority messages indicate a severe situation that needs immediate

response from the operator.

• Yellow – Medium Priority messages indicate a serious situation that requires prompt

operator attention.

• Blue – Low Priority messages indicate situations that the operator needs to be aware of.

4.1.3.4. Acknowledgment and clearing of messages

Messages will automatically clear and be removed from the screen when the event that

generated the message is resolved. Users may also manually acknowledge the message and

remove messages from the screen even if event is still present. Users can manually

acknowledge and clear messages by touching the individual message from the message stack

that they want to clear. Each message will display a [X] at the end as shown below as a visual

indicator that user action is needed. By closing the message the user acknowledges the

message and it will only reappear if the triggering condition is met again.

4.1.3.5. Exceeding Message Display Limit

In the event there are multiple, simultaneous messages exceeding the displayable area of 10

stacked messages, a high priority flashing and sound will be triggered along with the high

priority message in the eleventh and top position flashing “SEE MESSAGES!” This 11

and top

position is reserved for only the “SEE MESSAGES” message. As users start to acknowledge

and clear the messages, any yet to be displayed message will be appear according to priority in

the newly created real-estate.
