   May 10, 2024 · Normal average oxygen saturation levels are from 95-100% for healthy people (from children to older adults). For people with chronic diseases, their normal levels may be lower. A healthcare provider can advise on what individualized oxygen saturation range is considered normal for a person. Hypoxia is low oxygen levels in tissue.

   May 21, 2024 · Oxygen is a colorless, odorless, tasteless gaseous chemical element which appears in great abundance on Earth, trapped by the atmosphere. Many people are familiar with oxygen, because it is a vital component of the respiration process; without it, most organisms will die within minutes.

   How does oxygen get into the atmosphere?

   • Oxygen is generated as a byproduct of this process, and it enters the atmosphere for other organisms to use. While there, carbon attaches to oxygen and carbon dioxide is formed, which means carbon dioxide enters the atmosphere again.

   Who discovered oxygen?

   • Oxygen was discovered in England by Joseph Priestley in 1774. Carl W. Scheele had also discovered oxygen in Sweden in 1771, but his account had gone unpublished until 1777. Standard oxygen is colorless, tasteless, and has no odor. The name oxygen is derived from two Greek words, oxys which means acid and genes which translate to forming.
