• UNIT: to change the display units of CO2 and InsCO2 parameters. "mmHg" and "kPa" are available for
selection.
• Exit: to close CO2 SETUP menu.
Note
"APNEA ALM" cannot be closed.
• OTHER SET: pick this item in the menu to call up CO2 more setup sub-menu.
Figure 16-5 CO2 More Setups Menu
Now we introduce you to the functions of each item in CO2 SETUP submenu.
• WAVE SCALE: to adjust full scale size of CO2 waveform display area with "LO" or "HI" selectable.
The default value is "LO".
• WORK MODE: in the MainStream measurement ,you must set the work mode to "MEASUREMENT".
• ATMOS:This setting is used to set current Barometric Pressure.
Resolution: 1 mmHg (400mmHg~850mmHg), Default:760mmHg.
• O2 COMPENSATE:Use this setting to correct for the compensation of the gas mixture administered to the
patient. Resolution: 1% (0~100%), Default: 16%.
• BALANCE GAS: Use this setting to correct for the compensation of the gas mixture administered to the
patient. "room air", "N2O", "Helium" Will be selected. Default: "room air".
• ANEA: Use this setting to correct for the compensation of the gas mixture administered to patient.
Resolution: 0.1% (0.0~20.0%), Default: 0.0%.
Note
• Anesthetic agent is ignored when the balance gas is set to helium.
• Zero: A "Sample Cell Zero "is a quick process that allows the module to accommodate the optical
characteristics of each of the different adapter type ..A Sample Cell Zero should be performed whenever
the type of adapter being used with the module is changed. For optimal accuracy , a Sample Cell Zero
should also be performed whenever the module is connected to the host system.
Note
• No routine calibration required.An airway adapter zero is required when changing to a different style of
airway adapter.
• To perform a Sample Cell Zero:
1. Set the Host to the zeroing function.
2. Connect the CO2 Module and, if necessary, wait for the sensor warm-up message to clear.
3. Connect a Sampling accessory to the module ,and make certain that the accessory is exposed to room
air and away from all sources of CO2,including the ventilator ,the patient's breath and your own.
4. Start the Sample Cell Zero .The maximum time is 40 seconds .The typical time for a zero is 15-20
seconds.
• When not using CO2 monitoring function, it is suggested that the " WORK MODE" should be adjusted to
"STANDBY" .
• DEFAULT: pick this item to access the CO2 DEFAULT CONFIG dialog box, in which the user may select
whether the FACTORY DEFAULT CONFIG or the USER DEFAULT CONFIG is to be used. After selecting
any of the items and exiting the dialog box, the system will pop up the dialog box asking for the user's
confirmation.
EtCO2 upper alarm limit: when parameter value exceeds this limit, there will be alarm for exceeding the
upper limit.
