z
Use only SPO2 sensors provided by manufacturer for SPO2
measurements. Other SPO2 sensors may cause improper
performance.
z
Do not use an SPO2 sensor with exposed optical components.
z
Excessive patient movement may cause inaccurate
measurements.
z
Tissue damage can be caused by incorrect application or use of
sensor, for example by wrapping the sensor too tightly. Inspect
the sensor site to ensure skin integrity and correct positioning
and adhesion of the sensor. More frequently inspection should
be taken depend on different patients if necessary.
z
Set the upper limit of SPO2 alarm to 100% means cut off the
upper alarm. High density of oxygen will cause adverse
affection to the neonate .So the upper limit of SPO2 alarm must
be selected prudently according to the acknowledge clinical
practice.
z
Inaccurate measurements may be caused by:
z
Incorrect sensor application or use
z
Significant levels of dysfunctional hemoglobins (such as c
arboxyhemoglobin or methemoglobin)
z
Intravascular dyes such as indocyanine green or methylene blue
z
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
z
High-frequency electro surgical interference and defibrillators
z
Venous pulsations
z
Placement of a sensor on an extremity with a blood pressure cuff,
arterial catheter, or intravascular line
z
The patient has hypotension, severe vasoconstriction, severe
anemia, or hypothermia
z
There is arterial occlusion proximal to the sensor
z
The patient is in cardiac arrest or is in shock
z
Loss of pulse signal can occur in any of the following situations:
z
The sensor is too tight
z
There is excessive illumination from light sources such as a
surgical lamp, a bilirubin lamp, or sunlight
z
A blood pressure cuff is inflated on the same extremity as the one
to which an SPO2 sensor is attached
