3 Open the CO2 port door and insert the FilterLine connector. Using the tabs, screw the

FilterLine connector into the CO2 port clockwise until it can no longer be turned. Do not use

excessive force.

4 Verify that the CO2 area is displayed. The EtCO2 monitor performs the autozero routine as

part of the initialization self-test.

Note: If you use a ventilation system, do not connect the FilterLine set to the patient/

ventilation system until the EtCO2 monitor has completed its self-test and warm-up.

5 Display CO2 waveform in Channel 2.

6 Connect the CO2 FilterLine set to the patient.

7 Confirm that the EtCO2 value and waveform are displayed. The monitor automatically selects

the scale for the best visualization of the waveform. You can change the scale, if desired, as

described in the next section.

Note: It is possible for the FilterLine set to become loose at the device connection and still

have an EtCO2 value and CO2 waveform, but they may be erroneously low. Make sure the

FilterLine connection is firmly seated and can no longer be turned.

Note: The capnography module performs self-maintenance within the first hour of monitoring

and once an hour during continuous monitoring. The self-maintenance includes “auto-

zeroing.” Self-maintenance is also initiated when the surrounding temperature changes 8°C

(14.4°F) or more, or the surrounding pressure changes more than 20 mmHg. The CO2

module detects this change and attempts to purge the tubing. To clear the

or CO2 FILTERLINE BLOCKAGE messages, remove the FilterLine tubing and

reconnect it to the monitor.
