RR Filter Enable/Disable
The respiration rate filter makes respiration rate counting
more accurate in the presence of artifact, and is only
valid when the LoFlo module is in use. Pressing the:
• RR Filter Enable softkey turns the respiration rate
filter on.
• RR Filter Disable softkey turns the respiration rate
filter off.
Note that when the RR filter is in use, the E Series
adapts more slowly to sudden changes in respiratory
rate.
Alarms
The E Series EtCO
2
option provides user programmable
“out-of-range” alarms for both EtCO
2
and respiration
rate.
The EtCO
2
and respiration rate alarms share the same
State field, therefore you cannot enable or disable them
separately. Enabling the EtCO
2
alarms enables both
EtCO
2
and respiration rate alarm functions; disabling
EtCO
2
or respiration rate alarms disables both functions.
See the E Series Operator’s Guide for details on
enabling, disabling, and suspending alarm functions on
the E Series unit.
When the EtCO
2
and respiration rate alarm states are
set to AUTO, the unit automatically sets the lower and
upper limits for EtCO
2
and respiration rate.
For EtCO
2
, the unit sets the upper and lower alarm limits
to +/- 25% of the patient's currently measured CO
2
value. If the EtCO
2
value is greater than 40 mmHg
(equivalent to 5.3 kPa or 5.3% at a barometric pressure
of 760 mmHg), then 10 mmHg (1.3 for kPa or %) is
added and subtracted from the current reading to set the
upper and lower limits. The auto alarm limits are set only
if valid measurements are present for the vital sign.
For the automatic respiration rate alarm limits, the unit
sets the upper and lower limits for respiration by adding
and subtracting the values shown in the following table
to/from the patient's current breath rate.
See “Default Settings” on page 14 for low and high alarm
limit default values and ranges.
Recorder Operation
If EtCO
2
measurements have been taken, press the
RECORDER button to print a stripchart that includes the
following values across the top part of the paper:
• Date and time
• ECG lead and size
• Heart rate
• EtCO
2
value
• Respiration rate
The recorder runs continuously until the button is
pressed again. If selected, the capnogram is also printed
at a fixed scale of 40 mmHg/cm, under the ECG trace.
All waveforms printed by the recorder are delayed by
six seconds relative to their occurrence.
Automated External Defibrillator (AED)
Operation
E Series AED units equipped with the EtCO
2
option
operate in a slightly different way than Manual Advisory
models equipped with EtCO
2
.
Semi-Automatic Operation
The EtCO
2
monitoring parameters can be changed by
pressing the Param softkey, as outlined in “Physiological
Monitoring” on page 10. The capnogram waveform
cannot be displayed in semi-automatic mode.
Although EtCO
2
alarm functions are operational in
semi-automatic mode, heart rate alarm functions are
disabled. Background ECG analysis functions continue
to operate as described in the “AED” section of the
E Series Operator’s Guide.
The ALARM SUSPEND button can be used to activate,
deactivate, or audibly disable the EtCO
2
alarms (as
described in the E Series Operator’s Guide). The alarm
limit settings cannot, however, be changed in
semi-automatic mode; only the default alarm limits are
available. See the E Series Configuration Guide for
information on setting alarm limit defaults.
Manual Mode Operation
When the AED unit is in manual mode, the unit can
display the capnogram waveform as described in
“Displaying the Capnogram Waveform” on page 10.
Both heart rate and EtCO
2
alarms are operational. The
alarm limits can be changed by pressing the Alarms
softkey. The EtCO
2
monitoring parameters can be
changed by pressing the Param softkey, as outlined in
“Physiological Monitoring” on page 10.
