Operating the CO2 Module
WARNING
Risk of inadequate monitoring.
When operating the CO
2 module within an
inspiratory CO2 concentration range higher
than 3.5 Vol.%, situations may occur in which
breathing phase-derived gas measurement
values cannot be calculated. If this is the case,
the related alarm monitoring will not be active.
In order to guarantee gas monitoring, it is nec-
essary to activate the bypass mode for
inspiratory CO
2 concentration settings above
3.5 Vol.%.
WARNING
Risk of inadequate monitoring.
Apnea monitoring for CO
2 and pressure mea-
suring is not active when the bypass mode is
used (as described above). Flow apnea alarm
monitoring is not active in the Man/Spont
mode and therefore must be replaced by a
continuously active lower minute volume (MV)
limit.
To achieve this, activate the MV alarm limits
for Man/Spont on the configuration screen by
setting them to "on" and make sure that the
MV lower alarm limit is active whenever venti-
lating the patient.
WARNING
Risk of inadequate monitoring.
CO
2 concentration monitoring alarms are not
active when the bypass mode is used (as
described above). The user must exercise
increased attentiveness. The user must manu-
ally monitor measured CO
2 concentrations,
which will not be based on breathing phases
in the bypass mode, by observing the dis-
played CO
2 waveform. In addition, gas mea-
surement availability must be constantly
supervised because CO
2 apnea alarm moni-
toring is unavailable.
