Explosion Hazard: Do not use in the presence of flammable anesthetics or gases, such as a flammable
anesthetic mixture with air, oxygen or nitrous oxide. Use of the devices in such an environment may
present an explosion hazard.
Failure of operation: if the measurement or a sensor fails to respond as described, do not use it until
the situation has been corrected by qualified personnel.

intubated patients, a sample of the respiratory gas is drawn from the patient's breathing circuit through
an airway adapter and a gas sampling tube. With non-intubated patients, the gas sample is drawn
through a nasal or oral-nasal cannula.
