6. Press RESPONSE to select either NORMAL, SLOW, or FAST.
The FAST setting 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.
A SLOW response will decrease ETCO
2
false alarms when breath morphology varies
considerably from one breath to the next.
The default setting is NORMAL.

7. Set alarm limits for ETCO
2
, INCO
2
, and Breath Rate.
Motion artifact or other factors can cause false RR/BR alarms. To help minimize false
alarms, the Propaq delays or “holds off” triggering a RR/BR alarm for 5 seconds. After
this holdoff period begins, if the Propaq detects that the patient’s RR/BR vital sign has
returned to acceptable limits, the Propaq cancels the alarm holdoff. The next time a
RR/BR limit is violated, the Propaq starts a new 5-second RR/BR alarm holdoff period.
8. Set the alarm limit for Apnea Delay—this is the maximum time allowed between two
successive breaths before an Apnea alarm occurs.
After the first breath has been detected, the Apnea alarm limit setting will be
automatically turned on for as long as the CO
2
channel is active. The RR/BR and
Apnea Alarm Limit window is shown below. STAT SET does not affect the Apnea
limit.
Response Time
Setting Sampling Period Typical Indications for Use
FAST 15 seconds During neuroanesthesia
NORMAL 30 seconds During routine use
SLOW 45 seconds To decrease ET CO
2
false alarms
WARNING For patient safety, it is recommended that the Breath Rate alarm
limits always be turned on and set appropriately.
