8.3.5 Oximetry sensor (oximeter)
Use the cleaning instructions as section 8.1.
•
Caution at cleaning:
o
Do not steam-sterilize, pressure-sterilize, or gas-sterilize the Oximeter
o
Do not wet up or dive the monitor into any liquid.
o
Use cleaning solutions with moderation. Excess solution may run into the
monitor and cause internal damages to the components.
o
Do not touch, press, or scrub the display panel with abrasive cleaning
components, brushes, cleaning instruments, and do not leave it in contact with
anything to scratch the panel.
o
Do not use solutions derived by petroleum or acetones, or other abrasive
solvents to clean the oximeter
. These substances attack the device’s materials
and may result in its failure.
•
Inaccurate measures may be caused by:
o
Incorrect sensor application or use
o
Significant levels of dysfunctional hemoglobin. (e.g., carboxyhemoglobin or
methemoglobin)
o
Intravascular dyes such as indocyanine green or methylene blue.
o
Exposure to excessive illumination, such as surgical lamps (especially ones
with a xenon light source), bilirubin lamps, fluorescent lights, infrared heating
lamps, or direct sunlight (exposure to excessive illumination can be corrected
by covering the sensor with a dark or opaque material)
o
Excessive patient movement.
o
Venous pulsations.
o
Placement of a sensor on an extremity with a blood pressure cuff, arterial
catheter, or intravascular line.
•
Loss of pulse signal can occur in any of the following situations:
o
The sensor is too tight
o
There is excessive lighting from light sources with a surgical lamp, a bilirubin
