Understanding the Different Types of Portable Oxygen Devices
Globally, many individuals face health challenges that limit oxygen intake. This condition, known as hypoxia, requires supplemental oxygen delivery, either intermittently or continuously. The advent of portable oxygen concentrators (POCs) in the early 2000s has significantly improved mobility and quality of life for those affected.
POCs are essential tools for hypoxia management, enabling users to carry oxygen wherever they go and operate as needed.
