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.
Clinical application of pulse oximeters: SpO
2
is an
important physiological parameter to reflect the
respiration and ventilation function, so SpO
2
monitoring
used in treatment has become more popular. (For example,
such as monitoring patients with serious respiratory
disease, patients under anesthesia during operation and
premature and neonatal infants) The status of SpO
2
can be
determined in timely manner by measurement and will
allow finding the hypoxemia patient earlier, thereby
preventing or reducing accidental death caused by
hypoxia effectively.
