waveform scale or range.

3.
Press mm/s to set the display sweep speed for CO
2
and RESP (3.13, 6.25, or 12.5
mm/sec). The default is 6.25.
To view the sweep speed setting, press MORE to access the CO
2
status window.

If O

or N
2
O is being administered to the patient, press GAS COMP to set the proper
gas compensation (for specifications, see
“Capnography (CO2) specifications”
page 103). If no gas is being administered, choose OFF (the default).
6.
Press RESPONSE to set CO
2
measurement response time (NORMAL, FAST, or
SLOW).
FAST is recommended where a sudden step change in ETCO
2
is of concern, such as
that induced by an air embolus in certain neurosurgical procedures. SLOW is
recommended to help reduce ETCO
2
false alarms when breath morphology varies
considerably from one breath to the next. The default is NORMAL.

Note
If an inspired value is displayed indicating patient rebreathing (non-zero INCO
2
),
check the patient breathing circuit for proper function. For mainstream CO
2
, also
remove the sensor from the patient’s airway, hold it away from any source of
breath, and confirm INCO
2
begins to go down to the baseline value. If the Propaq
CS monitor continues to display inspired values, return the mainstream CO
2
sensor to Welch Allyn for service.
Note
If ETCO
2
is displayed as + + +, have a biomedical technician check the CO
2
calibration against a known reference gas. If the sensor calibration is not accurate,
return it to Welch Allyn for service.
