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
important physiological parameter to reflect the respiration
and ventilation function, so SpO
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 SpO
and find the hypoxemia patient earlier, thereby preventing
or reducing accidental death caused by hypoxia effectively.
3 Normal SpO
In campagna area, healthy people's SpO
than 94%, so the values below 94% are determined as
hypoxia. SpO
for determining anoxia by most researchers, so SpO
limit of the oximeter is set as 90% generally.
4 Factors affecting SpO
 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
