Oxygen Concentrator Content  Oxygen concentrator content An oxygen concentrator is a medical device that concentrates oxygen from ambient air and delivers it to a patient in need of supplemental oxygen. It works by drawing in air through a series of filters and then separating the nitrogen and other gases from the oxygen using a molecular sieve. The oxygen is then delivered to the patient through a nasal cannula or mask. The main components of an oxygen concentrator include: Compressor: This draws in ambient air and compresses it. Air filter: This removes impurities from the compressed air. Molecular sieve: This separates the nitrogen and other gases from the oxygen. Oxygen flow meter: This controls the rate of oxygen flow to the patient. Oxygen sensor: This monitors the concentration of oxygen in the output. Pressure regulator: This controls the pressure of the oxygen. Cannula or mask: This delivers the oxygen to the patient. Oxygen concentrators are used to treat a range of conditions, including chronic obstructive pulmonary disease (COPD), asthma, and sleep apnea. They are also commonly used in hospitals and clinics to treat patients with respiratory distress.
