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 O
2
when directly exposed to laser,
electrosurgical devices, or high heat. Use with caution to prevent flammability of the FilterLine
tubing.
Fire hazard.
Anesthetics become mixed with the patient’s air that is sampled by the capnometer. When using
the EtCO
2
monitor in the presence of flammable anesthetic mixture with oxygen or nitrous oxide,
connect the EtCO
2
gas port to a scavenger system.
Possible inaccurate patient assessment.
The EtCO
2
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 CO
2
readings.
Using other manufacturers’ CO
2
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 CO
2
readings.
If calibration is not performed as specified in the Service Manual for the LIFEPAK 20e
defibrillator/monitor, the EtCO
2
monitor may be out of calibration. A monitor that is out of
calibration may provide inaccurate readings.
