optical analysis window is dirty, the monitor will display the "check adapter" alarm. If

the user attempts to zero the module, the procedure will cause an error. At this point,

the module will not work properly and will continue to prompt the "check adapter" or

"adapter need replace" warnings. If the user attempts to clean the module but the

warning and alarms persist, a new adapter should be connected. Baseline elevation

will cause the ETCO2 readings to be high. When a new adapter is connected, the

module will automatically carry out a return to zero operation. This process can last

about 15 seconds and the user should ensure that no respiratory gases enter the

adapter during this time.

10.4 CO2 Compensations

The measurement of CO2 is affected by temperature, pressure and gas

compensations. The barometric pressure, as well as the presence of O2, N2O,

Helium, and anaesthetic agents in the gas mixture need to be compensated for by

the device in order to achieve its stated accuracy. The device provides instrument

settings to allow the user to communicate these operating conditions. Please set the

correct settings according to your operation environment the first time you use this

monitor. The settings can be found in the ETCO2 set up menu.

The "Apnea Time(s)" is the maximum time allowed from the detection of one breath

to the next breath. Therefore, if the time between breaths exceeds the time out

period, the alarm "Apnea" will be triggered.

At start-up, or following a zero operation, three breaths need to be detected before

this timer is activated. To clear the "Apnea" alarm, three breaths are required, or a

zero operation must be carried out.

Note: The ETCO2 monitor is not an apnea monitor. The software cannot discriminate

between the patient no longer breathing and a sensor that has been disconnected

from the patient circuit.

Cleaning the CO2Module case, Cable and connector:

Use a cloth dampened with isopropyl alcohol 70%, a 10% aqueous solution of

sodium hypochlorite (bleach), a 2% glutaraldehyde solution, ammonia, mild soap

or disinfectant spray cleaner.

Wipe down with a clean water-dampened cloth to rinse and dry before use.

NOTE: Do not immerse or sterilise the Module.
