Oxygen Therapy

Oxygen therapy (pronunciation: /ˈɒksɪdʒən θɛrəpi/) is a treatment that provides you with extra oxygen, a gas that your body needs to function normally.

Etymology

The term "oxygen" comes from the Greek words "oxys" meaning "sharp" and "genes" meaning "producer". The term "therapy" comes from the Greek "therapeia" meaning "healing".

Definition

Oxygen therapy involves supplying an increased concentration of oxygen to the lungs, helping to improve oxygen levels in the patient's blood. This therapy is often prescribed for people with diseases that prevent them from getting enough oxygen naturally, such as chronic obstructive pulmonary disease (COPD), pneumonia, asthma, and COVID-19.

Types of Oxygen Therapy

There are several types of oxygen therapy, including:

  • Nasal cannula: A device that delivers oxygen through two small tubes that go into the patient's nostrils.
  • Oxygen mask: A mask that covers the nose and mouth, providing a higher concentration of oxygen.
  • Hyperbaric oxygen therapy: A treatment in which the patient breathes pure oxygen in a pressurized room or tube.

Risks and Complications

While oxygen therapy can be life-saving, it can also cause side effects and complications. These may include dry or bloody nose, skin irritation, and oxygen toxicity, which can damage the lungs and other organs.

Related Terms

  • Hypoxia: A condition in which there is not enough oxygen in the body or a region of the body.
  • Hypoxemia: A condition in which there is a lower than normal level of oxygen in the blood.
  • Pulse oximetry: A test used to measure the oxygen level (oxygen saturation) of the blood.
