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 MD 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 MD 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 MD unit issues an equipment alert and displays
the message FILTERLINE OCCLUSION. At this point, if
the current FilterLine is correctly attached, replace the
FilterLine.
VALUE OVER RANGE
The CO
2
value exceeds the specified range.
CO2 DISABLED
An error has occurred with the CO
2
module, and the
Propaq MD unit has disabled the module for the duration
of the unit’s power cycle. If the problem persists, the unit
may require servicing.
