An oxygen concentrator takes in air and removes nitrogen from it, leaving an oxygen-enriched gas for use by people requiring medical oxygen due to low oxygen levels in their blood. [4] Oxygen concentrators provide an economical source of oxygen in industrial processes, where they are also known as oxygen gas generators or oxygen generation plants.
The system cannot be deactivated once triggered, and must be reloaded after each use. [4] On-board oxygen generating systems (OBOGS) bleed compressed air from the engines, enrich the oxygen content by removing nitrogen using an oxygen concentrator, and regulate the supply to cabin pressure and temperature. They are continuously available and ...
Smoking drastically reduces oxygen intake efficiency, and can have the effect of reducing tolerance by 1,000–2,000 metres (3,300–6,600 ft). [4] Hypoxia can be produced in a hypobaric chamber. This can be useful for identifying individual symptoms of hypoxia, along with rough estimates of the altitude that causes problems for each person.
Traditionally, colonoscopy prep involves drinking a large amount of liquids (an oral laxative formula) to help you clean out your colon. Now, there are other options that help you achieve the same ...
A portable oxygen concentrator (POC) is a device used to provide oxygen therapy to people that require greater oxygen concentrations than the levels of ambient air. It is similar to a home oxygen concentrator (OC), but is smaller in size and more mobile. They are small enough to carry and many are now FAA-approved for use on airplanes.
Postpolypectomy coagulation syndrome (Postpolypectomy syndrome or PPCS) is a condition that occurs following colonoscopy with electrocautery polypectomy, which results in a burn injury to the wall of the gastrointestinal tract. The condition results in abdominal pain, fever, elevated white blood cell count and elevated serum C-reactive protein.
Aerobic" is defined as "relating to, involving, or requiring oxygen", [3] and refers to the use of oxygen to meet energy demands during exercise via aerobic metabolism adequately. [4] Aerobic exercise is performed by repeating sequences of light-to-moderate intensity activities for extended periods of time. [2]
He began using a bicycle ergometer to measure sustained performance in terms of a person's ability to use oxygen. In 1968, he published Aerobics, which included exercise programs using running, walking, swimming and bicycling. At the time the book was published there was increasing awareness of the need for increased exercise due to widespread ...
