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.
Sidestream CO

Monitoring
Setting up for Sidestream CO
2
monitoring requires these major steps:
1. Connect the watertrap.
2. Set up the CO
2
channel and alarm limits.
Warning For patient safety, it is recommended that the Breath Rate alarm
limits always be turned on and set appropriately.
Warning If the Sidestream CO
2
option is connected to a ventilatory circuit, be
sure to adjust appropriate ventilator or anesthesia system settings to
compensate for the sampling flow volume (90 or 175 ml/min) that is aspirated
from the ventilatory circuit by the Sidestream CO
2
option.
Do not use Sidestream CO
2
if flammable anesthetic gases are in use.
