EtCO2 Warnings and Cautions
WARNINGS!
Fire hazard.
Before use, carefully read these operating instructions, the FilterLine
®
tubing directions for use,
and precautionary information.
Fire hazard.
The FilterLine tubing may ignite in the presence of O2 when directly exposed to laser,
electrosurgical devices, or high heat. Use with caution to prevent flammability of the FilterLine
tubing.
Fire hazard.
Flammable anesthetics become mixed with the patient’s air that is sampled by the capnometer.
When using the EtCO2 monitor in the presence of flammable gases, such as nitrous oxide or
certain other anesthetics, connect the EtCO2 gas port to a scavenger system.
Possible inaccurate patient assessment.
The EtCO2 monitor is intended only as an adjunct in patient assessment and is not to be used
as a diagnostic apnea monitor. An apnea message appears if a valid breath has not been
detected for 30 seconds and indicates the time elapsed since the last valid breath. It must be
used in conjunction with clinical signs and symptoms.
Possible inaccurate CO2 readings.
Using other manufacturers’ CO2 accessories may cause the device to perform improperly and
invalidate the safety agency certifications. Use only the accessories that are specified in these
operating instructions.
Possible inaccurate CO2 readings.
If calibration is not performed as specified in the Service Manual for the LIFEPAK 20e
defibrillator/monitor, the EtCO2 monitor may be out of calibration. A monitor that is out of
calibration may provide inaccurate readings.
Possible strangulation.
Carefully route the patient tubing (FilterLine) to reduce the possibility of patient entanglement or
strangulation.
