High-priority alarms need to be handled immediately.
The operator can judge whether the alarm system is working through visual alarm signals and
auditory alarm signals. The operator of the Anaesthesia workstation shall accurately detect the
visual alarm signal at 4m, and this visual indication is on the display screen. The sound pressure
level of the alarm signal shall not be lower than 60dB at the position of 1m on the horizontal plane
of the geometric center in front of the equipment.
