9.1 Alarm Levels
The infusion pump provides users with a variety of status information about itself and its infusion process. If
any exception is detected, the infusion pump generates an alarm and informs users in the form of sound, light,
and character.
Based on the criticality of the exception information, alarms are classified into three levels: low, middle,
and high. The following table describes the sound-light presentation mode of these three levels of alarm. The
alarm volume ranges from 45 dB to 85 dB.
