How Does Oxygen Therapy Work? Understanding the Mechanism

Oxygen therapy is a medical treatment that involves the administration of oxygen to a person who has difficulty breathing. The therapy is designed to improve the oxygen levels in the blood and help the body function more efficiently. But how exactly does oxygen therapy work?

In healthy individuals, the air we breathe contains approximately 21% oxygen. However, in some medical conditions, the body requires more oxygen to function properly. Oxygen therapy provides the additional oxygen needed to help the body heal or function more efficiently.

The oxygen is delivered to the body through a variety of means, such as a mask, a nasal cannula, or a ventilator. The mask or nasal cannula delivers the oxygen directly to the nose, allowing it to be inhaled into the lungs. A ventilator is a machine that helps with breathing and is used for individuals who have more severe breathing difficulties.

Once the oxygen is inhaled into the lungs, it is absorbed into the bloodstream and transported to the rest of the body. The increased oxygen levels in the blood help improve the function of the heart and other organs, and can also help reduce the symptoms of conditions such as COPD, emphysema, and pneumonia.

The Importance of Adequate Oxygen Levels

Adequate oxygen levels are essential for good health and proper body function. Oxygen is needed to fuel the body’s cells and tissues, and is also necessary for the proper functioning of the heart and other organs. When the body does not receive enough oxygen, it can lead to a variety of health problems, including fatigue, shortness of breath, and an increased risk of heart and lung damage.

It is important to note that oxygen therapy is not a cure for underlying medical conditions, but it can help manage symptoms and improve overall health and well-being.


Oxygen therapy is a safe and effective treatment for individuals who have difficulty breathing. By increasing the oxygen levels in the blood, oxygen therapy can help improve breathing, reduce symptoms, and improve overall quality of life. If you have questions or concerns about oxygen therapy, it is important to talk to your healthcare provider to determine if it is right for you.
