29. SpO2 Measurement
The concentration of oxygen saturation (SpO2) means the saturation level of hemoglobin which can
transport the oxygen of the arterial blood. The current transport level for the capacity of hemoglobin to
transport the oxygen is expressed as a percentage.
WARNING
Strong light such as from surgical lamps (especially ones with a xenon light source), bilirubin
lamps, fluorescent lights, infrared heating lamps, or direct sunlight interferes with accurate
measurement.
You may cover the sensor with gauze to shield the sensor from direct light that may affect the
sensor readings.
This monitor is not approved to be used in an MRI environment. Sensors in an MRI suite via
induction may cause severe burns to patients.
Do not place the SpO2 probes at the site where the arterial catheter or the venous infusion
set is connected.
High humidity environments may damage the sensor and cause erroneous readings.
CAUTION
Sensor accuracy may be compromised in poorly perfused patients.
Accuracy of the SpO2 sensor may be compromised in patients with abnormalities in the
peripheral nervous system including hypothermia, hypovolemia, hyperdynamia of vessels, or
reduction in heart rate.
Accuracy may be compromised with patients having an abnormal increase in oxyhemoglobin
or methemoglobin.
Place the sensor so that the light transmitter and receiver are directly opposite each other,
with the patient tissue to be measured between them.
Consistent observation and care is required to protect the patient from skin injury from
continuous pressure of the sensor.
NOTE
If results are not available at all or are inaccurate, please check the following:
-
Reposition the sensor or change to another part of the body to correct poor or inaccurate
readings.
-
Check if the sensor is properly placed.
-
The sensor site should be clean and free of oils and lotions.
