4.
Connect the gas outlet to the scavenging system using an exhaust tube.
After the CO
2
module is connected, it enters measure mode by default and the monitor displays
CO2 Starting
.
CO
2
can be measured after the start-up is complete.
WARNING
•
Do not apply adult or pediatric watertrap to the neonate patient. Otherwise, patient injury could
result.
•
Connect the gas outlet to the scavenging system when measuring CO
2
using the sidestream CO
2
module.
CAUTION
•
Check the compatibility of the CO
2
adapter and the sampling line before use.The CO
2
adapter is
intended for connecting an Oridion CO
2
sampling line.
•
Leakage in the breathing or sampling system may cause the displayed EtCO
2
values to be
significantly low. Always make sure that all components are securely connected.
•
Inspect the airway adapter for a tight connection and proper operation before attaching it to the
patient.
•
Squeezing or bending the sample line during the sidestream or microstream CO
2
measurement may
cause inaccurate CO
2
reading or no reading.
•
To avoid blocking the airway, empty the DRYLINE II watertrap container whenever half full.
Replacing the DRYLINE II watertrap once a month is recommended.
•
The DRYLINE II watertrap has a filter preventing bacterium, water and secretions from entering the
module. Extended use could destroy the filter in watertrap and fail to stop the bacterium, water and
secretions entering the module, result in damaging the gas module and having infection risk.
NOTE
•
It is recommended to replace the CO
2
adapter at least once a year.
•
To extend the lifetime of the watertrap and module, disconnect the watertrap from the module and
set the operating mode to Standby mode when CO
2
monitoring is not required.
•
The sample rates are different when different types of watertraps are used.
•
The emptying interval of the DRYLINE II adult/pediatric watertrap is 26 hours @ 120 ml/min, 37 °C,
and 100% RH.
•
The emptying interval of the DRYLINE II neonatal watertrap is 35 hours @ 90 ml/min, 37 °C, and
100% RH.

Preparing to Measure CO
2
Using Microstream CO
2
Module
To prepare the CO
2
module for measurement, follow this procedure:
1.
Connect one end of the sample line to the microstream CO
2
module.
