Intelligent alarm behavior

Combined alarms

If multiple alarms occurring at the same time are
caused by the same problem, they are combined
into one alarm.
Problem
Several causes of apnea are
present.
Faults in multiple components.
This causes failure of a system
function.

Suppressed alarms

Some low-priority alarms indicate a fault in a
measurement function. If this measurement
function monitors physiological parameters, alarms
based on these parameters will not be generated.
