10.6 Activation of alarms after breath detection
Devices equipped with inspiratory O2 measurement and integrated patient-
gas measurement module
In the Man/Spon mode, the alarms for Minute volume low and Apnea (no flow) are
only activated after spontaneous breaths have been detected.
Devices equipped with integrated patient-gas measurement module
If still no breaths have been detected after leaving the Standby, Pause, or
Monitoring modes, the breathing gas is monitored with regard to an O
2
concentration that is too low or an anesthetic gas concentration that is too high. At
the same time, the message Waiting for respiratory phases is displayed in the
CO
2 waveform.
Once 2 breaths have been detected, the message disappears and only then are the
O
2, CO2, N2O, and anesthetic gas alarms active.
