7.3 Technical Alarms
A technical alarm, as apposed to a physiological parameter alarm, is an alarm condition that
exists no matter whether a patient is connected to the machine. Technical alarms include:
 Power-on self-test alarms
 CPU board runtime alarms
 Power board runtime alarms
 Electronic flowmeter and BFCS runtime alarms
 VCM runtime alarms
 Electronic vaporizer runtime alarms
 AGSS module runtime alarms
 Auxiliary O2/air module runtime alarms
 HFNC module runtime alarms
 Internal AG module runtime alarms
 Plug-in module runtime alarms
Before troubleshooting the anesthesia machine, check for technical alarm messages. If a technical
alarm is generated, evaluate the alarm first.
The following sections detail how to troubleshoot technical alarms related to the modules
mentioned above.
For detailed information on possible causes for other alarm and prompt messages, see the user
