PRELIMINARY
3
Warnings
•
Explosion Hazard:
Do NOT use
OXYPLETH
in the presence of flammable anesthetics. Use of
this instrument in such an environment may present an explosion hazard.
•
Electrical Shock Hazard:
Always turn
OXYPLETH
off and remove line cord before cleaning
it. Do NOT use a damaged sensor or one with exposed electrical contacts. Refer servicing to
qualified service personnel.
• Do not operate
OXYPLETH
when it is wet due to spills or condensation.
• Do not operate
OXYPLETH
if it appears to have been dropped or damaged.
•
Patient Safety:
Extreme care should be exercised with neonates to assure continued circulation
distal to the sensor site after application.
•
Failure of Operation:
If the monitor fails to respond as described, do not use it until the
situation has been corrected by qualified personnel.
•
Patient Safety:
Care should be exercised to assure continued peripheral perfusion distal to the
SpO
2
sensor site after application.
•
Data Validity:
Inaccurate SpO
2
and/or Pulse Rate measurements can be caused by any of the
following:
• Incorrect application or use of a sensor
• Significant levels of dysfunctional hemoglobin such as carboxyhemoglobin or methemoglobin
• Significant levels of indocyanine green, methylene blue, or other intravascular dyes
• Exposure to excessive illumination such as surgical lamps—especially ones with a xenon light
source, or direct sunlight
• Excessive patient movement, venous pulsations, electrosurgical interference
•
Data Validity:
The Pulse Oximeter should not be used as a substitute for an ECG monitor. The
oximeter’s Pulse Rate display reflects the pulsatile flow found at the patient extremity
connected to the sensor. This rate can be affected by many factors and may occasionally be
“frozen.”
•
Do
NOT
attach an SpO
2
sensor distal to a blood pressure cuff. Valid data
CANNOT
be
processed when the cuff is inflated. Attach the sensor to the limb opposite to the site used for
the blood pressure cuff.
•
Do
NOT
apply Y-Sensor tapes or wraps so tightly that the circulation is restricted. Inspect site
often for adequate circulation - at least once every four hours. When applying sensors take note
of the patient’s physiological condition. For example, burn patients may exhibit more sensitivity
to heat and pressure and therefore additional consideration such as more frequent site checks
may be appropriate.
WARNING
Indicates a potentially harmful condition that can lead to personal injury
