Note: To decrease the likelihood of the FilterLine connection coming loose during use,
hand-straighten the tubing after removal from the package before connecting to patient or
device.
3 Open the CO
2
port door and insert the FilterLine connector. Using the tabs, screw the
FilterLine connector into the CO
2
port clockwise until it can no longer be turned. Do not use
excessive force.
4 Verify that the CO
2
area is displayed. The EtCO
2
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 EtCO
2
monitor has completed its self-test and warm-up.
5 Display CO
2
waveform in Channel 2.
6 Connect the CO
2
FilterLine set to the patient.
7 Confirm that the EtCO
2
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 EtCO
2
value and CO
2
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 CO
2
module detects this change and attempts to purge the tubing. To clear the CO2 FILTERLINE
PURGING or CO2 FILTERLINE BLOCKAGE messages, remove the FilterLine tubing and
reconnect it to the monitor.
