Oxygen Levels

Oxygen is a colourless, odourless gas that makes up about 21 percent of the air. It is essential for cell respiration in all living organisms, and animals and plants need it to live. Low oxygen levels can result in symptoms such as breathlessness and fatigue. Oxygen levels can be measured in the environment with special instruments, or measured in the bloodstream using a pulse oximeter. Oxygen levels are important to our health and well-being, so monitoring oxygen levels is essential to ensure safe and healthy living conditions.
