What Is Oxygen Concentrator?
An oxygen concentrator is a device that pulls in ambient air, filters out nitrogen, and delivers concentrated oxygen through a nasal cannula or mask. It is used medically and in hyperbaric oxygen therapy.
Classification: Other › Oxygen Concentrator
Key Takeaway
Oxygen concentrators are reliable medical devices for home oxygen therapy and HBOT setups. They deliver much higher oxygen concentration than ambient air.
Why This Matters
Oxygen concentrators are the standard equipment for home supplemental oxygen therapy, replacing earlier oxygen tanks for most long-term use. They draw in room air (about 21% oxygen) and use a molecular sieve to remove nitrogen, delivering air that is typically 90%+ oxygen. They are also commonly used with soft-shell hyperbaric oxygen chambers to provide the higher concentration of oxygen needed for HBOT. Medical use requires a prescription and appropriate flow rate; wellness-oriented HBOT programs also use concentrators under specific protocols.
