What is the function of an oxygen concentrator?

• A. To store liquid oxygen for later use
• B. To deliver high-flow oxygen for emergencies
• C. To extract oxygen from the surrounding air for medicinal use
• D. To mix oxygen with helium for specialized treatments

Answer: (C)

The function of an oxygen concentrator is to extract oxygen from the surrounding air for medicinal use. This device operates by using a process called pressure swing adsorption, which separates oxygen from nitrogen and other gases present in the atmosphere. The concentrator draws in air, filters it, and concentrates the oxygen, delivering it at a higher purity level suitable for patients who require supplemental oxygen therapy due to various medical conditions. This method is particularly advantageous over other options, as it allows for a continuous supply of oxygen without the need for large storage tanks or liquid oxygen supplies. Moreover, oxygen concentrators are portable and can operate on electricity, making them convenient for at-home use or during travel. The design is focused on providing a steady flow of oxygen directly from ambient air, which suits the needs of individuals with chronic respiratory issues. While the other functions mentioned may be related to some oxygen delivery systems or specific medical situations, they do not accurately describe the primary purpose or mechanism of an oxygen concentrator.
