13.7 Changing CO
2
Settings
When CO
2
Monitoring is selected, the respiration parameter will be provided by CO
2
module. That is, respi-
ration waveform area shifts to CO
2
waveform area, respiration parameter area shifts to CO
2
parameter area.
Select “Menu”

“CO
2
” to enter into CO
2
related setting.
In RESP settings window, CO
2
Settings can be entered if your monitor is configured with CO
2
monitoring .
: click it to turn on or off CO
2
Monitoring. When the CO
2
monitoring is selected,
then all items setting as “RESP” will shift to “CO
2
”. See Chapter Monitoring Carbon Dioxide (CO
2
) .
On RESP Settings screen, there is CO
2
Monitoring Switch : click it to turn on or
off CO
2
Monitoring. It is recommended that the switch is turned on only when there is a need to monitor CO
2
parameter. This can not only reduce the power consumption and also extend the life of the CO
2
measurement
module.
In order to maintain the monitor, please set CO2 switch at OFF state in system setup when CO2 function
is not used.
•
Gain
: the CO
2
waveform gain. 4 options: X1/2, X1, X2 and X4. The default is X1 for adult and pediatric pa-
tient, and X2 for neonate patient.
X1 waveform scale with base gain X1/2 half scale size of the base gain
X2 twice scale size of the base gain X4 four times scale size of the base gain
•
Speed
: Respiration waveform sweeping speed of, 2 options 6.25mm/s and 12.5 mm/s. The default is 12.5
mm/s.
• Apnea(s) : The timeout setting for apnea alarm (in second).
(1). When CO
2
monitoring is on:
It can be set as any number from 10 to 60 seconds, the step is 1 second. Icon “ ” displays on
the upper right corner of Respiration Panel; When the device has not detected any breathing signal for the
specified time, the “Apnea” alarm prompts on, and alarm sound will be activated. If it is set as OFF, the icon
“ ” displays on lower left corner of the Respiration Panel. The default is 20s.
(2). When CO
2
monitoring is off: refer to Section Changing RESP setting.
•
Source
: Respiration signal source. This item is fixed to be “CO
2
” if CO
2
monitoring function is selected.
Otherwise, the source will be obtained from thoracic impedance measurement from ECG module.
• Zero : press it to perform zero resetting.
• Default : resume to the factory default value.
•
Unit
: It can be set up as “%”, “kPa” and “mmHg”. If the unit is changed, then the parameter value will
change and refresh timely. The unit will be displayed on parameter area, the default is “mmHg”.
• Period : setting the calculating cycle of the EtCO
2
value, there are three selectable options: “1b”, “10s” and
“20s”. The default is “10s”. “1b” means the EtCO
2
value will be calculated once every respiration cycle;
“10s” means the EtCO
2
value will be calculated once every 10 seconds, and the maximum EtCO
2
value
measured during this 10s will be displayed on data area; “20s” means the EtCO
2
value will be calculated
once every 20 seconds, and the maximum EtCO
2
value measured during this 20s will be displayed on data
area.
•
Balance
: setting the balance gas in patient’s respiration air flow. There are three kinds of selectable balance
gas: “Air”, “N
2
O” and “He”, namely: air, nitrous oxide and helium. If no specific balance gas is given, the
balance gas can be set as “Air”.
• O
2
Comp .: adjusting the concentration of the compensating gas in patient’s respiration air flow. Generally,
the compensating gas is Oxygen, so it can be called oxygen compensation concentration. The unit: %;
Setting range: 1~100%. Default value: 16.
• TEMP(°C) : setting the temperature value of the current measured air flow. For instance, the temperature is
usually set as 37°C while measuring the patient’s respiration by air flow. However, if the air flow to be meas-
ured is the reference gas, the temperature is set as 25°C. The setting range: 0.0 ~ 50.0; Unit: °C; Default
value: 35.0°C.
• Agent : setting whether adding the anesthetic gas to patient’s respiration air flow and the concentration of
anaesthetic gas. The setting range is 0.0%~20.0%, the default status is: not adding anaesthetic gas, that’s
to say, the concentration is 0.0%.
• Flow (CO
2
flow) : It is flow rate of the CO
2
sampling. Its value is 50ml/min.
• Barometric (Barometric pressure) : set ambient atmospheric pressure. It can be determined by barometer
or the ambient altitude. Altitude can be used to determine the typical barometric pressure if a barometer is
not available, refer to Appendix Typical Pressures and CO
2
Readings at Altitudes for details.
