How EtCO
2
is Displayed
The E Series unit displays the numeric EtCO
2
value in
units of mmHg, unless configured for percent or kPa.
Refer to the
E Series Configuration Guide
(Part No.
9650-1201-01) for instructions on how to configure
alternate units of measure. The unit also displays the
number of breaths per minute, labeled "RR" for
respiration rate. In addition, a capnogram may be
displayed using the
Wave 2
softkey.
Displaying the Capnogram Waveform
The E Series unit can display one or two waveforms in
Monitor, Defib, or Manual (AED) mode, as long as the
defibrillator is not charging or ECG analysis is not in
progress. The unit displays only one waveform in Pacer
mode.
Note
If you don’t see the CO
2
display box on the monitor,
check the sensor cable connection to the E Series
unit. The CO
2
box is not displayed if the sensor is
not connected to the unit. Once the box is
displayed, after power-on, it remains displayed
even if the sensor is disconnected from the unit.
With EtCO
2
monitoring, the unit can display a capnogram
below the ECG trace for a visual indicator of the
moment-by-moment CO
2
values. The unit displays the
capnogram at half the speed of the ECG display, and
provides 8 seconds of data.
The unit temporarily removes the second waveform from
the display when the user presses the
CHARGE
,
ANALYZE
, or
ENERGY
SELECT
buttons, or the
Sync
On/Off
softkey. The unit restores the second waveform
to the display 4 seconds after:
•
a shock is delivered
•
an analysis is completed, unless the defibrillator is
charging
•
the last
Energy
Select
button press
•
Sync mode is turned off
To cycle the display from the capnogram, to the
plethysmograph waveform (if SpO
2
is installed), to no
second waveform displayed, press the
Wave 2
softkey.
Use the
Zoom
softkey from the EtCO
2
submenu to
adjust the waveform display size. Numbers shown on the
left side of the capnogram display indicate the scaling.
Physiological Monitoring
The physiological monitoring menu includes the
following softkeys:
Param
,
Wave 2
,
ID#
,
Alarms
, and
12
Lead
.
Param Softkey
When you press the
Param
softkey, the following
softkeys are displayed:
Select
,
Enter
, and
Return
.
Press the:
•
Select
softkey to scroll among the different available
physiological parameters.
•
Enter
softkey to select the parameter that is
highlighted.
•
Return
softkey to return to the physiological
monitoring menu.
Selecting the EtCO2 parameter causes the following
softkeys to appear:
Zero, Disable EtCO2
(or
Enable
EtCO2), Zoom, MORE
, and
Return
.
Pressing the:
•
Disable EtCO2
softkey puts the sensor into the
power saving sleep mode.
•
Enable EtCO2
takes the sensor out of sleep mode
and turns the heater on for normal operation.
•
MORE
softkey causes the following softkeys to
appear:
Average, Comp., RR Filter Disable,
(or
RR
Filter Enable
),
MORE
, and
Return
.
•
Return
softkey returns you to the physiological
monitoring menu.
See the next sections for a description of the Zero and
Zoom softkey functions.
Pressing the MORE softkey causes the previous
selections to appear. Pressing the Return softkey returns
the user to the physiological monitoring menu. Refer to
the sections “Average Softkey,” “Comp. Softkey,” and
“RR Filter Enable/Disable” for descriptions of those
softkey functions.
