II Common Knowledge
1 Meaning of SpO2
SpO2 is the saturation percentage of oxygen in the blood, so
called O2 concentration in the blood; it is defined by the
percentage of oxyhemoglobin (HbO2) in the total hemoglobin
of the arterial blood. SpO2 is an important physiological
parameter to reflect the respiration function; it is calculated by
the following method:
SpO2 = HbO2/ (HbO2 +Hb)×100%
HbO2 are the oxyhemoglobins (oxygenized hemoglobin), Hb
are those hemoglobins which release oxygen.
2 Principle of Measurement
Based on Lamber-Beer law, the light absorbance of a given
substance is directly proportional with its density or
concentration. When the light with certain wavelength emits
on human tissue, the measured intensity of light after
absorption, reflecting and attenuation in tissue can reflect the
structure character of the tissue by which the light passes.
Due to that oxygenated hemoglobin (HbO2) and
deoxygenated hemoglobin (Hb) have different absorption
character in the spectrum range from red to infrared light
(600nm~1000nm wavelength), by using these characteristics,
SpO2 can be determined. SpO2 measured by this oximeter is
the functional oxygen saturation -- a percentage of the
hemoglobin that can transport oxygen. In contrast,
hemoximeters report fractional oxygen saturation – a
percentage of all measured hemoglobin, including
dysfunctional hemoglobin, such as carboxyhemoglobin or
metahemoglobin.
![](/img.php?id=3405229&img=bg30.png)
User Manual for Handheld Pulse Oximeter
43
Clinical application of pulse oximeters: SpO2 is an important
physiological parameter to reflect the respiration and
ventilation function, so SpO2 monitoring used in clinical
becomes more popularly, such as monitoring the patient with
serious respiratory disease, the patient under anesthesia
during operation, premature and neonate. The status of SpO2
can be determined in time by measurement and find the
hypoxemia patient earlier, thereby preventing or reducing
accidental death caused by hypoxia effectively.
3 Normal SpO2 Range and Default Low Limit
In campagna area, healthy people’s SpO2 value is greater
than 94%, so the values below 94% are determined as
hypoxia. SpO2<90% is considered as the default threshold for
determining anoxia by most researchers, so SpO2 low limit of
the oximeter is set as 90% generally.
4 Factors affecting SpO2 accuracy (interference reason)
Intravascular dyes such as indocyanine green or
methylene blue
Exposure to excessive illumination, such as surgical
lamps, bilirubin lamps, fluorescent lights, infrared
heating lamps, or direct sunlight.
Vascular dyes or external used color-up product such
as nail enamel or color skin care
Excessive patient movement
Placement of a sensor on an extremity with a blood
pressure cuff, arterial catheter, or intravascular line
Exposure to the chamber with High pressure oxygen
There is an arterial occlusion proximal to the sensor

hyperkinesias or body temperature decreasing
5 Factors causing low SpO2 value (pathology reason)
Hypoxemia disease, functional lack of HbO2
Pigmentation or abnormal oxyhemoglobin level
Abnormal oxyhemoglobin variation
Methemoglobin disease
Sulfhemoglobinemia or arterial occlusion exists near
sensor
Obvious venous pulsations
Peripheral arterial pulsation becomes weak
