Carbon Dioxide Safety Information
Cautions • Only use Microstream™ etCO
2
sampling lines to ensure the monitor functions
properly.
• Microstream™ etCO
2
sampling lines are designed for single patient use, and are not to
be reprocessed. Do not attempt to clean, disinfect, sterilize or flush any part of the
sampling line as this can cause damage to the monitor.
• Use of a CO
2
sampling line with H in its name (indicating that it is for use in humidified
environments) during MRI scanning may cause interference. These sampling lines
include CapnoLine™ H/Long, CapnoLine™ H O
2
, Smart CapnoLine™ H/Long, Smart
CapnoLine™ H O
2
, and Smart CapnoLine™ H Plus O
2
/Long. The use of non H sampling
lines is advised.
•CO
2
sampling lines used with the monitor are marked with the upper limit of oxygen
that may be provided with the sampling line. At levels of oxygen provision higher than
those marked on the sampling line packaging, dilution of CO
2
readings may occur,
leading to lower CO
2
values.
• Ensure that tubing is not stretched during use.
• Dispose of sampling lines according to standard operating procedures or local
regulations for the disposal of contaminated medical waste.
• When monitoring with capnography during sedation, please note that sedation may
cause hypo-ventilation 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.
• When monitoring patients during upper endoscopy, 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 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.
• Entry of dust or fluids into the CO2 intake of the Microstream™ CO2 will cause
blockage of the narrow channels. When a FilterLine is not inserted, the Microstream™
CO2 has no protection from fluid or dust entry. A spring-loaded door covers the input
connector when a FilterLine is not inserted.
