Setting the CO
2
Sweep Speed
The EtCO
2
sweep speed determines the X-axis scale of the capnogram. For patients with
slower respiration rates, a slower sweep speed will make the capnogram easier to view. You can
specify sweep speeds of 3.13, 6.25, and 12.5 mm/second. The default sweep speed is
6.25 mm/second.
System Messages
When monitoring CO
2
, the Propaq M unit may display the following messages:
System Message Cause
INITIALIZING The unit is initializing the CO
2
monitoring function
measurement, is functioning normally, and will display
CO
2
measurement after a brief delay.
CHECK FILTERLINE The sampling line is not connected. Check
sampling line connection. Replace airway adaptor
or cannula, if defective.
FILTERLINE OCCLUSION The sampling or exhaust line is blocked. Check
sampling and exhaust lines. Make sure that the
sampling line and any inputs to the patient
breathing apparatus are not connected to the
exhaust port.
If the current FilterLine is correctly
attached, replace the FilterLine.
AUTO ZERO The Propaq M unit displays AUTO ZERO when the
CO
2
module performs periodic self-maintenance.
During self-maintenance, the CO
2
module performs
one or more of the following tests: ambient pressure
measurement, auto zero, and a flow test. The CO
2
module completes its self-maintenance tests in
approximately 10 seconds.
PURGING The CO
2
module performs a purging whenever it
detects an occlusion in the line or airway adaptor,
and displays PURGING while it tries to clear the
occlusion. If the CO
2
module cannot clear the
occlusion within 30 seconds, the Propaq M unit
issues an equipment alert and displays the
message FILTERLINE OCCLUSION.
At this point, if
the current FilterLine is correctly attached, replace the
FilterLine.
