Oxygen-Enriched Atmospheres: Applications & Examples

* The Earth's atmosphere contains about 21% oxygen, which is essential for life on Earth.

* Hyperbaric oxygen therapy (HBOT) involves breathing pure oxygen in a pressurized chamber. HBOT is used to treat a variety of conditions, including decompression sickness, carbon monoxide poisoning, and severe burns.

* Oxygen tents were once used to treat patients with respiratory problems, such as pneumonia and tuberculosis. Oxygen tents are still sometimes used in emergency situations, such as when a patient is in respiratory distress.

* Oxygen concentrators are devices that remove nitrogen from the air and deliver pure oxygen to patients with chronic respiratory conditions, such as COPD and emphysema.

* Oxygen cylinders are portable tanks that contain compressed oxygen. Oxygen cylinders are used by patients with respiratory problems who need to use oxygen on a regular basis, such as when traveling or exercising.
