The pulse oximeter uses two rays with different wavelengths which strike the finger inside
the housing to take measurements. A low oxygen saturation rate is primarily caused by
illness (respiratory illnesses, asthma, heart failure, etc.).
People with a low oxygen saturation rate often experience the following symptoms: short-
ness of breath, increased heart rate, impaired performance, nervousness and perspira-
tion. Chronic and known low oxygen saturation requires monitoring with your pulse
oximeter under medical supervision.
An acute low oxygen saturation, with or without symptoms, requires immediate medical
attention. This could be a sign of a life-threatening condition. The pulse oximeter is there-
fore particularly suited for high-risk patients such as persons with heart disease, asthma, as
well as for athletes and healthy persons in high altitudes (e.g. mounting climbers, skiers or
amateur pilots).
