Monitoring
7.1 Summary
The carbon dioxide monitor are used during respiratory Ventilator therapy, for patient gas
monitoring, used in adults, children, babies.
CO2 module using the principle of gas having absorption characteristics with infrared to
measure the gas concentration.All the gases that can be measured by the module can absorb
the infrared and each gas has it’s own absorption characteristics.The gas sent to a sampling
room ,infrared filter select a particular band infrared thread the gas.If measure with several
gases, then it will have a number of infrared filter.In a given volume,the higher the gas
concentration,the more infrared absorbed,the less the transmission volume of infrared that
thread the gas. Through measuring the transmission volume of infrared can calculate the gas
concentration.
CO2 module only monitor the gas concentration of CO2. Also divided into Main stream
（
IRMACO2
）
and Side stream(ISA CO2).
NOTE

For guarantee the safty of the patient, when operate this Ventilator you need to
monitor the anesthetic and CO2.If the anesthetic system doesn’t configure anesthetic
gas module or (and) CO2 module, please use the module that having anesthetic gas or
(and) CO2 monior function which comply with relevant standard requirements to
ensure the anesthetic system can realize the monitoring of anesthetic gas and CO2 in
the meatime.

Rise to 10kPa periodic pressure doesn’t affect the performance of gas monitor.
7.2 Monitoring ways
7.2.1 Main stream
IRMA main stream CO2 module is install it’s probe to the airway adapter, then insert the
airway adapter to the connection port between endotracheal tube and breathing circuit
Y-shaped tube, the module through the two sides window of the IRMA airway adapter to
read the respiratory gas measurement value.The two sides windows of airway adapter use the
special design and material, can prevent performance degradation due to water vapor.
NOTE

Main stream IRMA module can only be used by trained or authorized medical staff.

IRMA module can not be used in flammable anesthetic gas environment.

IRMA modulebanned for MRI environment.

To avoid cross-infection, do not reuse disposable IRMA airway adapter.

The used disposable airway adapter should be disposed according to local medical
waste disposal regulations.

If IRMA airway adapter occurs water droplets / condensation, replace the adapter.
