Warning
• Check CO
2
and O
2
tubing regularly during use to ensure that
no kinks are present. Kinked tubing may cause inaccurate
CO
2
sampling or affect O
2
delivery to patient.
Cautions
• Securely connect all components. Loose connections or failure to
correctly insert the oral prong into the Smart SureLine 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
2
waveform distortion
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
2
is delivered at flow rates greater than 10 l/min, the patient’s
exhaled CO
2
may be diluted, producing attenuated waveforms and
EtCO
2
values.
• If CO
2
insufflation is performed during CO
2
monitoring, the EtCO
2
values will accordingly rise very significantly and this may result
in device alarms and abnormally high waveforms until the CO
2
is
evacuated from the patient.
• Expect delay times for the following products to be longer than
the standard by the given times: Long (4m) Smart SureLine
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
2
readings may occur, leading to
lower CO
2
values.
