General informaon about oxygen saturaon in blood:
Your oxygen saturaon in blood uctuates throughout the day. Hypoxemia, or low
blood oxygen, describes a lower than normal level of oxygen in your blood. In order
to funcon properly, your body needs a constant level of oxygen circulang in the
blood to cells and ssues. When this level of oxygen falls below a certain amount,
hypoxemia occurs and you may experience shortness of breath.
Your doctor determines whether you have hypoxemia by measuring your blood oxy-
gen level — the amount of oxygen traveling in your arteries. Your blood oxygen can
be measured by tesng a sample of blood from an artery. (Resource: Mayo Family

NantLife pulse oximeter, a small device that clips on your nger, measures the satu-
raon of oxygen in your blood; the results are oen used as an esmate of blood
oxygen levels. Normal pulse oximeter readings range from 95 to 100 percent, under
most circumstances. Values under 90 percent are considered low.
If you monitor your blood oxygen regularly, you will discover more about your
body’s reacons to external inuences (e.g. stress, air polluon or exercise), and
you will be able to consciously develop a healthier lifestyle.
