Cautions
• Securely connect all components. Loose connections or failure to
correctly insert the oral prong into the Smart CapnoLine Guardian™
channel may cause an inaccurate measurement of respiratory gases.
The oral prong must remain in the channel throughout the procedure.
• Ensure that tubing is not stretched during use.
• Sedation may cause hypoventilation and CO
or disappearance. Waveform attenuation or disappearance is an
indicator that the status of the patient's airway should be assessed.
• Partial blockage of the oral airway due to endoscope positioning
may cause periods of low readings and rounded waveforms. The
occurrence will be more pronounced with high oxygen delivery
levels.
• If O is delivered at flow rates greater than 10 l/min, the patient's

• If CO insufflation is performed during CO

values will accordingly rise very significantly and this may result
in device alarms and abnormally high waveforms until the CO
evacuated from the patient.
• Expect delay times for the following products to be longer than
the standard by the given times: Long (4m) Smart CapnoLine
Guardian™ - 3 seconds.
• The Guardian is recommended for use with oxygen provided at up
to 10l/min, or 5l/min with the sampling line alone. At higher levels
of oxygen provision, dilution of CO
