Cautions (Continued)
Do not use the airway adapter tube if the airway adapter tube is below 5 °C (41 °F). An airway adapter tube that is below
5 °C (41 °F) may frost, causing a false reading. Warm the airway adapter tube to above 5 °C (41 °F) by putting it in a warm
place (for example, in your hands or in a vehicle) prior to use.
An airway adapter that is between 5 °C (41 °F) and 10 °C (50 °F) may cause inaccurate reading due to fogging of optical
surfaces. It is recommended that the airway adapter tube be warmed to above 10 °C (50 °F) before use.
This device is designed to determine the percentage of arterial oxygen saturation of functional hemoglobin. Factors that
may degrade pulse oximeter performance or affect the accuracy of the measurement include the following:
- excessive ambient light
- excessive motion
- electrosurgical interference
- blood flow restrictors (arterial
catheters, blood pressure cuffs,
infusion lines, etc.)
- moisture in the sensor
Portable and mobile RF communications equipment can affect medical electrical equipment.
A functional tester cannot be used to assess the accuracy of a pulse oximeter monitor or sensor.
Remove earrings from the patient's ear before applying the Ear Clip sensor.
Water or other liquid between the airway adapter tube and the CO
Ensure that all connections to the airway adapter tube are tight and leak-free, and that the airway adapter tube is properly
attached to the CO
sensor.
2
Ensure that this device, the airway adapter tube, and the sensors have stabilized at the specified environmental operating
conditions before use.
Gastric distention with air prior to intubation may introduce CO
Observe six breaths before interpreting results.
This device's CO
detector must not be used with gaseous anesthetics.
2
Do not block the audible indicator speaker holes. Blocking the speakers will significantly reduce the sound volume.
Verify that the audible alarms can be heard over the ambient noise of the operating environment.
Failure of a network data coupling (serial cable/connectors) will result in loss of data transfer.

- improperly applied sensor
- incorrect sensor type
- inadequate signal
- venous pulsations
- anemia or low hemoglobin
concentrations
sensor may cause erroneous readings.

into stomach and esophagus and yield false results.

Indications for Use
- cardiogreen and other intravascular
dyes
- carboxyhemoglobin
- methemoglobin
- dysfunctional hemoglobin
- artificial nails or fingernail polish
- residue (e.g., dried blood, dirt,
grease, oil) in the light path.
