Levels of blood oxygen saturation that are too
high may be caused by particularly quick and
deep breathing. The level may increase up to 100
per cent. However, this substantially reduces the
carbon dioxide content in the blood potentially
influencing the blood pH value balance. Breathing
air with an increased oxygen content (e.g. during
oxygen therapy) may also lead to increased levels.
Pulmonary emphysema
Asthma
Reduced respiration
Circulatory disturbance
Heart defect
Blood pH value disturbance
Low oxygen content in the ambient air
(e.g. in high-altitude mountains)
Increased oxygen consumption, e.g. through
physical exercise
For healthy people, a normal blood oxygen
saturation level of between 92 - 98 % is
measured. Diseases or conditions leading to blood
oxygen saturation levels that are too low
include:
