15.4.7 Setting the Flow Rate
For the sidestream CO
2
module, you can change the sampling rate of respiratory gas in the patient’s airway by setting
the flow rate. To set the flow rate, enter the [ CO2 Setup ] menu and select an appropriate setting from [ Flow Rate ].
WARNING

Please consider the patient’s actual bearing capability and select the appropriate flow rate when setting the
flow rate.
15.4.8 Setting up the CO
2
Wave
In the [ CO2 Setup ] menu, you can:

Select [ Wave Type ] and toggle between [ Draw ] and [ Fill ]:

[ Draw ]: The CO
2
wave is displayed as a curved line.

[ Fill ]: The CO
2
wave is displayed as a filled area.

Select [ Sweep ] and then select the appropriate setting. The faster the wave sweeps, the wider the wave is.

Change the size of the CO
2
waveform by adjusting the wave [ Scale ].
15.4.9 Setting RR Source
To set RR source:
1. Enter the [ CO2 Setup ] menu.
2. Select [ RR Source ] and then select a source or [ Auto ] from the dropdown list.
The [ RR Source ] settings of Resp and CO

, are linked. For details, please refer to Setting RR Source of chapter Resp .
15.4.10 Setting Barometric Pressure Compensation
Both sidestream and microstream CO
2
modules have the function of automatic barometric pressure compensation (the
system automatically measures the barometric pressure which the patient monitor is exposed to). However, the
mainstream CO
2
module does not have such function. For the mainstream CO
2
module, the default barometric pressure
is 760 mmHg. You must modify the barometric pressure based on the actual situation as follows:
1. Select [ Main Menu ]
→
[ Maintenance >> ]
→
[ User Maintenance >> ]
→
enter the required password
→
[ Module
Maintenance >> ]
→
[ Maintain CO2 >> ]
→
[ Calibrate CO2 >> ].
2. Select [ Barometric Pressure ] and then enter the value of barometric pressure to which the patient monitor is
exposed to.
WARNING

Be sure to set the barometric pressure properly before using the mainstream CO
2
module. Improper settings
will result in erroneous CO
2
reading.
