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.
[10] Breathing pure oxygen results in an elevated partial pressure of oxygen in the blood: a climber breathing pure oxygen at the summit of Mt. Everest has a greater arterial oxygen partial pressure than breathing air at sea level. This results in being able to exert greater physical effort at altitude.
Portable oxygen concentrator used with bottle humidifier POCs operate on the same principle as a home concentrator, pressure swing adsorption . [ 6 ] The basic set up of a POC is a miniaturized air compressor , a cylinder filled containing the sieve, a pressure equalizing reservoir and valves and tubes.
Oxygen therapy is the use of supplemental oxygen as medical therapy. [46] Acute indications for therapy include hypoxemia (low blood oxygen levels), carbon monoxide toxicity, cluster headache and decompression illness. It may also be prophylactically given to maintain blood oxygen levels during the induction of anesthesia. [47]
Medical oxygen storage tanks at the Royal Women's Hospital, Melbourne, Australia. Oxygen may be used for patients requiring supplemental oxygen via mask. Usually accomplished by a large storage system of liquid oxygen at the hospital which is evaporated into a concentrated oxygen supply, pressures are usually around 345–380 kPa (50.0–55.1 psi), [1] [2] or in the UK and Europe, 4–5 bar ...
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.
