Precautions for Use of the Pulse Oximeter
!
► Oximeter readings may be affected by the use of an electrosurgical unit (ESU)
► This pulse oximetry system is designed to determine the percentage of arterial oxygen
saturation of functional hemoglobin. Significant levels of dysfunctional hemoglobin,
such as methemoglobin, might affect the accuracy of the measurement.
►To prevent improper performance and/or patient injury, verify sensor and pulse
oximeter compatibility before use.
►A functional tester cannot be used to access the accuracy of a pulse oximeter monitor
or probe.
► Factors that may degrade pulse oximeter performance include the following
-
excessive ambient light
-
excessive motion
-
electrosurgical interference
-
arterial catheter, blood pressure cuffs, infusion lines, etc.
-
moisture in the sensor
-
improperly applied sensor
-
carboxyhemoglobin
-
methemoglobin
-
artificial nails
-
incorrect sensor type
-
poor pulse quality
-
venous pulsations
-
anemia or low hemoglobin concentrations
-
cardiovascular dyes
-
sensor not at heart level
-
dysfunctional hemoglobin
-
fingernail polish
►Refer to instruction for use accompanying the pulse oximeter and oximeter sensor for
additional warnings and cautions.
