Microstream CO
2 monitoring
CO2 display
On the Cockpit, the CO2 display consists of:
–CO
2 parameter field
–CO
2 waveform
CO2 parameter field
The CO2 parameter field contains the following
elements:
A etCO2 label
B Unit of measurement
C Crossed triangle symbol when the etCO
2 alarm
is turned off
D inCO2 label
E inCO
2 value – the level of CO2 in the airway
during inspiration, taken as the minimum value
within the measurement interval
F Crossed triangle symbol when inCO
2 alarms
are turned off
G Crossed triangle symbol when RRc alarms are
turned off
H RRc value – respiratory rate derived from the
CO
2 signal.
I RRc (respiratory rate) parameter label
J etCO
2 value – highest level of CO2 in the airway
during the expiratory phase within the
measurement interval
CO2 waveform
The M540 also displays an instantaneous CO2
waveform.
A Expiratory or alveolar plateau (level of CO
2 in
lungs ceases to increase significantly)
B End-tidal concentration point (end of expiratory
phase, where CO2 is measured)
C Onset of inspiratory phase
D Onset of expiratory phase
E Baseline during inspiration
