Introduction
Carbon Dioxide Detector
9847V determines approximate CO
2
changes in the airway of intubated animals by measuring the
absorption of mid-infrared light passed through the airway adapter tube. The approximate CO
2
concentration change is indicated by an eight-segment LED bar graph display. The CO
2
detector
relies on the assumption that the inhaled air contains minimal amounts of CO
2
.
Breaths are indicated when the CO
2
level increases by approximately 5 mmHg during exhalation. A
detected breath is indicated on the CO
2
bar graph and by an audible breath beep.
When no breath is detected:
1. A high priority animal audible alarm sounds.
2. The No Breath indicator blinks.
3. The lowest CO
2
bar graph segment is lit, and CO
2
readings are displayed with the next
breath detected.
Medium priority (equipment) alarms occur when:
• The CO
2
sensor is unplugged.
• The airway adapter tube is removed from the CO
2
sensor.
• The light path is blocked.
• A CO
2
sensor failure occurs.
A high priority (animal) alarm overrides a medium priority alarm. If the audible alarms are disabled,
the third and sixth bars are solidly lit.
