WARNING! Incorrectly applied sensors may give inaccurate readings.
2
Refer to the
sensor insert for proper application instructions.
WARNING! Do not autoclave, ethylene oxide sterilize, or immerse the sensors in liquid. This
may cause damage to the sensor which may cause inaccurate readings.
WARNING! Unplug the sensor from the oximeter before cleaning or disinfecting to prevent
damaging the sensor or monitor, and to prevent user safety hazards.
WARNING! Measurements made at sites with low perfusion are potentially inaccurate.
Always use measurements in conjunction with other clinical signs and
symptoms.
WARNING! SpO
2
measurements may be adversely affected in the presence of high ambient
light. Shield the sensor area (with a surgical towel, for example) if necessary.
WARNING! Dyes introduced into the bloodstream, such as methylene blue, indocyanine
green, indigo carmine, fluorescein, and patent blue V (PBV) may adversely
affect the accuracy of the SpO
2
reading.
WARNING! Any condition that restricts blood flow, such as use of a blood pressure cuff or
extremes in systemic vascular resistance, may cause an inability to determine
accurate pulse rate and SpO
2
readings.
WARNING! Optical cross-talk can occur when two or more sensors are placed in close
proximity. It can be eliminated by covering each site with an opaque material.
WARNING! Remove fingernail polish or false fingernails before applying SpO
2
sensors.
Fingernail polish or false fingernails may cause inaccurate SpO
2
readings.
WARNING! Significant levels of dysfunctional hemoglobins, such as carboxyhemoglobin
(with CO-poisoning) or methemoglobin (with sulfonamide therapy), will affect
the accuracy of the SpO
2
measurement.
WARNING! Tissue damage may result from overexposure to sensor light during
photodynamic therapy with agents such as verteporphin, porfimer sodium,
and metatetrahydroxyphenylchlorin (mTHPC). Change the sensor site at least
every hour and observe for signs of tissue damage. More frequent sensor site
changes/inspections may be indicated depending upon the photodynamic
agent used, agent dose, skin condition, total exposure time or other factors.
Use multiple sensor sites.
WARNING! When connecting this monitor to any instrument, verify proper operation
before clinical use. Refer to the instrument’s user manual for full instructions.
Accessory equipment connected to the monitor’s data interface must be
certified according to the respective IEC standards, i.e., IEC 60950 for data
processing equipment or IEC 60601-1 for electromedical equipment. All
combinations of equipment must be in compliance with IEC 60601-1-1 systems
requirements. Anyone connecting additional equipment to the signal input
port or the signal output port configures a medical system, and therefore is
responsible that the system complies with the requirements of the system
standard IEC 60601-1-1.
