NOTE 
  To extend the lifetime of the water trap and CO2 module, disconnect the water 
trap and set the working mode of the module to standby when CO2 monitoring is 
not required. 
  The CO2 measurement can be used, with specified accessories, with intubated and 
non-intubated adult, pediatric. With patients, a sample of the respiratory gas is 
drawn from the patient's breathing circuit through an airway adapter and a gas 
sampling line. 
 
CAUTION 
  The water trap collects water drops condensed in the sampling line and therefore 
prevents them from entering the module. If the collected water reaches a certain 
amount, you should drain it to avoid blocking the airway. Dispose of accumulated 
fluids in accordance with the hospital policy or your local regulations. 
  The water trap has a filter preventing bacterium, vapor and patient secretions 
from entering the module. After a long-term use, dust or other substances may 
compromise the performance of the filter or even block the airway. In this case, 
replace the water trap. Replacing the water trap once a month is recommended. 
Or, replace the water trap when it is detected leaky, damaged or contaminated.
