Oxygen therapy is a medical treatment that provides extra oxygen to the tissues of the body through the lungs, a process known as respiration.
What is the information for this topic?
Oxygen is a colorless, odorless, tasteless gas that is essential for the body to survive. The heart relies on oxygen to beat and pump blood. If not enough oxygen is circulating in the blood, it becomes increasingly difficult for the heart muscle to pump.
The air contains approximately 21 percent oxygen; normally, this is more than enough for an individual to maintain adequate oxygen in the blood just by breathing air through the lungs.
However, some medical conditions result in a shortage of oxygen to the tissues of the body, for different reasons. These
- asthma, a chronic disease causing intermittent narrowing of the airways
- chronic bronchitis, with long-
term irritation of the airways
- anemia, or a low red blood cell count
- pulmonary edema, a condition in which extra fluid accumulates in the lungs
- congestive heart failure, a condition in which a weakened heart fails to pump enough blood to the body cells
- pulmonary fibrosis, in which the lungs become scarred
