Oxygen Saturation (Medicine)

Oxygen saturation (pronounced: /ˈɒksɪdʒən sætʃəˈreɪʃən/) is a term used in medicine to refer to the extent to which hemoglobin in the blood is saturated with oxygen. It is usually expressed as a percentage, with normal levels typically between 95% and 100%.

Etymology

The term "oxygen saturation" is derived from the English words "oxygen" and "saturation". "Oxygen" (pronounced: /ˈɒksɪdʒən/) comes from the Greek words "oxys" meaning "sharp" and "genes" meaning "producer", referring to its role in producing acids. "Saturation" (pronounced: /sætʃəˈreɪʃən/) comes from the Latin word "saturare", meaning "to fill full".

Measurement

Oxygen saturation is typically measured using a device called a pulse oximeter. This non-invasive device uses light absorption through a patient's finger, earlobe, or toe to estimate the oxygen saturation level in the blood.
