Súrefniskonsentrator

Súrefniskonsentrator is an Icelandic term that translates to oxygen concentrator in English. An oxygen concentrator is a medical device used to deliver oxygen therapy to patients who have conditions that cause low blood oxygen levels. These conditions can include chronic obstructive pulmonary disease (COPD), pneumonia, heart failure, and lung cancer. The device works by taking in ambient air, which is composed of approximately 21% oxygen, 78% nitrogen, and 1% other gases. It then uses a process called pressure swing adsorption (PSA) to separate the nitrogen from the oxygen. The PSA process involves passing the air through a sieve material, typically zeolite molecular sieves, which traps the nitrogen molecules. The remaining gas, which is enriched in oxygen, is then delivered to the patient through a nasal cannula or a mask.

Oxygen concentrators are available in both stationary and portable models. Stationary units are typically used in a patient's home, while portable units allow individuals to maintain oxygen therapy while traveling or engaging in activities outside the home. The devices are powered by electricity and can be plugged into a standard wall outlet. Some portable models also have a battery backup for use during power outages or when away from an electrical source. The concentration of oxygen delivered by these devices is typically between 87% and 96% at a flow rate of 0.5 to 5 liters per minute, although some models can produce higher concentrations or flow rates. Continuous monitoring of oxygen saturation levels is important for patients using an oxygen concentrator to ensure the therapy is effective and safe.
