l
Check the airway adapter before using it. If the airway adapter is already damaged or destroyed, do not use
it.
During measuring, if the tube falls off, it is necessary to re-calibrate after connecting well for further measurement.
16.3.3 Measurement setting for mainstream CO
2
module
NOTE:
l
When using a new airway adapter, it must be zeroed as described in this section.
1.
Connect the sensor to the CO
2
module.
2.
The information "CO
2
SENSOR WARM UP" will display on the screen.
3.
After warm up, connect the sensor to the airway adapter.
4.
Refer to relative chapter for zeroing the sensor.
5.
After zeroing, connect the gas circuit as the following figure.
Errore. L'origine riferimento non è stata trovata.
NOTE:
l
Install the sensor above the adapter to prevent the liquid from gathering on the adapter window. The high
concentration of liquid at this location will hinder the gas analysis.
l
Use only sterile airway adapter or disposable airway adapter to avoid cross-contamination.
l
Check the airway adapter before using it. If the airway adapter is already damaged or destroyed, do not use
it.
l
Regularly check flow sensor and sampling tube to prevent excessive moisture or secretions gathering.

Setup” menu as shown below:
n
ALM REC: pick "ON", the system will output alarm information when CO
2
alarm occurs, the default is "OFF".
n
SWEEP: adjust the display speed of CO
2
waveform, three options: “6.25 mm/s”, “12.5 mm/s”, or “25.0 mm/s”.
n
UNIT: change the display units of CO

and InsCO
2
parameters. Two options: “mmHg” and “kPa”.

ALM SETUP:
Set the following contents after entering the initial password "70808":
u
ALM: when CO
2
alarm occurs, the system will prompt and store the alarm information after selecting
"ON", it will not alarm when selecting "OFF", and "
" will appear in parameter area.
u
ALM LEV: two options: HI and MED. "HI" is the most serious alarm, the second serious alarm is
"MED". The change of "ALM LEV" only effects the physiological alarm level of CO
2
parameters(including EtCO
2
upper limit, EtCO
2
lower limit, InsCO
2
upper limit, AwRR upper limit
and AwRR lower limit). The default level is "MED".
u
CO
2
ALM HI: adjust the upper limit of EtCO
2
alarm. If the measurement value is higher than CO
2
upper
alarm limit, the information “CO
2
TOO HIGH” appears on the screen. After the measurement value returns to
the normal one, the information disappears.
