GENERAL
The pulse co-oximeter is to be operated by, or under the supervision of, qualified
personnel only. The manual, accessories, directions for use, all precautionary
information, and specifications should be read before use.
WARNING

As with all medical equipment, carefully route patient cabling to reduce the possibility
of patient entanglement or strangulation.
 Do not place the pulse co-oximeter or accessories in any position that might cause it to
fall on the patient.
 Do not start or operate the pulse co-oximeter unless the setup was verified to be
correct.
 Do not use the pulse co-oximeter during magnetic resonance imaging (MRI) or in an
MRI environment.
 Do not use the pulse co-oximeter if it appears or is suspected to be damaged.
 Explosion hazard: Do not use the pulse co-oximeter in the presence of flammable
anesthetics or other flammable substance in combination with air, oxygen-enriched
environments, or nitrous oxide.
 To ensure safety, avoid stacking multiple devices or placing anything on the device
during operation.
 To protect against injury, follow the directions below:
o Avoid placing the device on surfaces with visible liquid spills.
o Do not soak or immerse the device in liquids.

o Use cleaning solutions only as instructed in this operator's manual.
o Do not attempt to clean the device while monitoring a patient.
 To protect from electric shock, always remove the sensor and completely disconnect
the pulse co-oximeter before bathing the patient.
 If any measurement seems questionable, first check the patient’s vital signs by
alternate means and then check the pulse co-oximeter for proper functioning
 Inaccurate SpCO and SpMet readings can be caused by:
o Improper sensor application
o Intravascular dyes such as indocyanine green or methylene blue
o Abnormal hemoglobin levels
o Low arterial perfusion
o Low arterial oxygen saturation levels including altitude induced hypoxemia
o Elevated total bilirubin levels
o Motion artifact
