Oxygen levels

Oxygen levels refer to the amount of oxygen in the air or in the blood. In the atmosphere, oxygen makes up about 21% of the air we breathe, which is essential for our lungs to extract and deliver oxygen to our body's cells. Inside the body, normal blood oxygen levels are typically between 95-100%. If these levels are low, it can indicate breathing problems or other health issues and may require medical attention. Maintaining proper oxygen levels is crucial because oxygen fuels all our body's functions, especially the brain and muscles.
