Using the 9847 Pulse Oximeter
Carbon Dioxide Detector
Verify:
• that the airway adapter tube is properly attached to the CO
2
sensor,
• the CO
2
sensor is properly connected to the device,
• the lower bar of the CO
2
display is lit,
• the CO
2
sensor light is blinking, and
• the CO
2
bar graph segments indicate change in CO
2
level.
Attach the CO
2
sensor/airway adapter tube to the patient’s endotracheal tube. The CO
2
detector will reflect
values and breath beeps for each breath (if the breath beep sound volume is not turned off).
Medium priority (equipment) alarm will occur (if the alarms are not disabled), when:
• the CO
2
sensor is disconnected,
• the airway adapter tube is removed from the CO
2
sensor,
• the light path is blocked, or
• a CO
2
sensor failure occurs.
High priority patient alarms override medium priority (equipment). The third and sixth
segments of the CO
2
bar graph will be illuminated, indicating a CO
2
sensor fault.
