etCO
2
Display
The etCO
2
parameter box displays the current
values for etCO
2
, iCO
2
and RRc. A lung icon
appears next to the RRc parameter label and
blinks every time a breath is detected. If the
Scio module is the signal source, the parameter
labels are marked with an asterisk (*). If alarms are set to Off, a
crossed-bell icon appears next to each parameter label.
NOTE: The etCO
2
waveform moves at 25% (~ 6.25mm/sec) of
the rate of other waveforms on the screen.
The illustration below depicts a normal etCO
2
waveform:
The letters A - E indicate the phases of the respiration cycle:
A-B Baseline (the level of minimum CO
2
concentration)
observed immediately after inspiration.
B-C Expiration phase.
C-D Expiratory plateau. The level of CO
2
in the lungs ceases
to increase significantly.
D End-tidal concentration point at the end of the expiration
phase, at which etCO
2
is measured.
D-E Onset of the inspiration phase.
