2. Oxygen tent - Wikipedia

   en.wikipedia.org/wiki/Oxygen_tent

   Oxygen therapy often benefits patients by providing more oxygen to their lungs and consequently to their tissues. Typically, the treatment raises the amount of oxygen in the blood, decreases load on the heart, and facilitates breathing. It can ease symptoms such as cough and dried up secretions that occur in respiratory conditions.

3. Glossary of breathing apparatus terminology - Wikipedia

   The International Pharmacopoeia specifies that Medical oxygen produced by air liquefaction has a purity of at least 99.5% oxygen by volume. The World Health Organization (WHO) specifies that for pressure swing adsorption (PSA) plants, medical oxygen produced from ambient air has 93±3% oxygen, and for oxygen concentrators, 82% from room air (21 ...

4. Breathing apparatus - Wikipedia

   en.wikipedia.org/wiki/Breathing_apparatus

   An oxygen concentrator is a device that concentrates the oxygen from a gas supply (typically ambient air) by selectively removing nitrogen to supply an oxygen-enriched product gas stream. They are also used industrially and as medical devices for oxygen therapy. [58] Two methods in common use are pressure swing adsorption and membrane gas ...

   Respiratory protective equipment (RPE), also called protective breathing equipment (PBE) in the US, [1] is a form of personal protective equipment designed to protect the wearer from a variety of airborne hazards in the form of a gas, fume, mist, dust or vapour.

7. Escape breathing apparatus - Wikipedia

   They may use a breathing hood, facepiece or mouthpiece and nose-clip as the user respiratory interface. Atmosphere-supplying apparatus may be rebreathers with a chemical or compressed gas oxygen supply, positive pressure demand apparatus, or constant flow apparatus using high pressure compressed air. Contamination of the breathing gas may be ...

8. Resuscitator - Wikipedia

   en.wikipedia.org/wiki/Resuscitator

   A resuscitator is a device using positive pressure to inflate the lungs of an unconscious person who is not breathing, in order to keep them oxygenated and alive. [citation needed] There are three basic types: a manual version (also known as a bag valve mask) consisting of a mask and a large hand-squeezed plastic bulb using ambient air, or with supplemental oxygen from a high-pressure tank.
