Cautions (Continued)
!
• This device is designed to determine the percentage of arterial oxygen
saturation of functional hemoglobin. Factors that may degrade pulse
oximeter performance or affect the accuracy of the measurement include the
following:
- excessive ambient light
- excessive motion
- electrosurgical interference
- blood flow restrictors (arterial catheters, blood pressure cuffs, infusion
lines, etc.)
- moisture in the sensor
- improperly applied sensor
- incorrect sensor type
- poor pulse quality
- venous pulsations
- anemia or low hemoglobin concentrations
- cardiogreen and other intravascular dyes
- carboxyhemoglobin
- methemoglobin
- dysfunctional hemoglobin
- artificial nails or fingernail polish
- a sensor not at heart level.
• A functional tester cannot be used to assess the accuracy of a pulse
oximeter monitor or sensor.
• All parts and accessories connected to the serial port of this device must be
certified according to at least IEC Standard EN 60950 or UL 1950 for data-
processing equipment.
• Operation of this device below the minimum amplitude of 0.3% modulation
may cause inaccurate results.
• Review all limits to ensure they are appropriate for the patient.
• The two-minute alarm silence is automatically engaged at startup.
