II Common Knowledge

1 Meaning of SpO

2

SpO

2

is the saturation percentage of oxygen in the blood, so

called O

2

concentration in the blood; it is defined by the

percentage of oxyhemoglobin (HbO

2

) in the total hemoglobin

of the arterial blood. SpO

2

is an important physiological

parameter to reflect the respiration function; it is calculated by
the following method:

SpO

2

= HbO

2

/ (HbO

2

+Hb)×100%

HbO

2

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

(HbO

2

)

and

deoxygenated hemoglobin (Hb) have different absorption
character in the spectrum range from red to infrared light
(600nm~1000nm wavelength), by using these characteristics,
SpO

2

can be determined. SpO

2

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.
