Carbon Dioxide Detector; Unpacking The Model 9847 - Nonin 9847 Operator's Manual

General Description

Carbon Dioxide Detector

9847 determines approximate CO changes in the airway of intubated patients by measuring the
2
absorption of mid-infrared light passed through the airway adapter tube. The approximate CO
2
concentration change is indicated by an 8-segment LED bar graph display. The CO detector relies on
2
the assumption that the inhaled air contains minimal amounts of CO .
2
Breaths are indicated when the CO level increases by approximately 5 mmHg during exhalation. A
2
detected breath is indicated on the CO bar graph and by an audible breath beep.
2
When no breath is detected:
• a high priority patient audible alarm sounds,
• the no breath indicator blinks,
• the lowest CO bar graph segment will be illuminated, and CO readings will be displayed with the
2 2
next breath detected.
Medium priority (equipment) alarms occur when:
• the CO sensor is unplugged,
2
• the airway adapter tube is removed from the CO sensor,
2
• the light path is blocked, or
• a CO sensor failure occurs.
2
A high priority (patient) alarm overrides a medium priority alarm. If the audible alarms are disabled, the
third and sixth bars will be solidly illuminated.
