Oxygen Therapy Devices Market Size Projected to Reach $69.59 billion by 2034 | 6.66%

The oxygen therapy devices market size stood at USD 39.09 billion in 2025 and is projected to increase from USD 41.55 billion in 2026 to USD 69.59 billion by 2034, registering a CAGR of 6.66% during the forecast period (2026–2034).

Oxygen therapy devices are used to deliver pure oxygen to the lungs under high atmospheric pressure. Under normal conditions, around 14.7 pounds per square inch of pressure with 21% of oxygen in inhaled, whereas oxygen therapy devices deliver 100% oxygen. This helps the oxygen molecules to condense and allow the intake of a higher amount of partial pressure of oxygen, where oxygen dissolves in the plasma around 10 to 15 times greater than normal.  

Super-saturation of oxygen in the body increases capillary growth, white blood cell (WBC) activity, new tissue development, oxygen tension in hypoxic areas, reduction in the size of gas bubbles, and numerous other physiological effects. The growing popularity of on-demand and continuous portable oxygen concentrators drives market growth. In line with this, the market players are channelizing efforts to develop technologically advanced oxygen therapy devices at competitive prices to sustain in the raging competition.
