Activation Of Alarms After Breath Detection; Intelligent Alarm Behavior; Combined Alarms; Suppressed Alarms - Dräger Perseus A500 Instructions For Use Manual

Activation of alarms after breath detection

If no breaths have been detected even after
leaving the Standby or Pause modes, the
breathing gas is monitored with regard to an O
concentration that is too low or an anesthetic gas
concentration that is too high, regardless of the
respiratory phase. At the same time, the message
Waiting for respiratory phases is displayed in

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.
Example:
Fault
CO measurement is faulty

Once 2 breaths have been detected, the message
and the symbol disappear. Only then, the
respiratory-phase-dependent O
anesthetic gas alarms are completely activated.
