Oxygen therapy is administered by use of oxygen gas as a medical intervention given acute or chronic patient care as it is essential for various cell metabolism whereas tissue oxygenation is essential for normal physiological function. Oxygen therapy is administered when the oxygen levels in blood is low. It can be administered in various ways from nasal to hyperbaric oxygen in a closed chamber. To understand how oxygen therapy is implemented in use, we need to understand the respiratory system. The respiratory system is a group of organs and tissues that help in breathing. The lungs and the nasal tract along with the wind pipe together form the respiratory system. The air enters the body through nose or mouth through the wind pipe to the lungs via bronchi. The bronchi branches out into several tubes called bronchioles, which further branch out into tiny air sacs known as alveoli. These tiny air sacs are covered with a mesh of blood vessels called capillaries, which are connected to several arteries and veins which transfer oxygen throughout the body. Certain acute or chronic disease conditions, which affect the transfer of oxygen from alveoli to the blood, such a pneumonia, cystic fibrosis, asthma, dysplasia, heart failure, sleep apnea, lung disorders, and COPD (chronic obstructive pulmonary disease). Oxygen therapy is administered on the basis of arterial blood gas test and a pulse oximetry test.

According to the World Health Organization (WHO), total deaths due to COPD is expected to rise approximately by 30% in the next decade, thereby driving the need to incorporate oxygen therapy as a treatment option. However it is estimated that COPD will be the third most fatal disease worldwide by 2024, thereby widening the consumer base for oxygen therapy market. The growing demand for technologically advanced system, such as portable oxygen concentrator system has also boosted global oxygen therapy market growth. Some of the major advancements include pulse oximetry devices, and nasopharyngeal oxygen therapy.
