The peripheral capillary oxygen saturation (SpO
total hemoglobin (Hb) in the blood, or the oxygen concentration in the blood. It is an important bio-
parameter for respiration. A number of diseases relating to the respiratory system may cause a decrease
of SpO in the blood. Furthermore, some other causes such as the malfunction of the body's self-

adjustment, damage during surgery, and injuries caused by some medical examinations could also lead to
a low oxygen supply in the human body. As a consequence, symptoms such as vertigo, impotence and
