Portable oxygen concentrators are life-saving medical devices. They provide supplemental oxygen to people with pulmonary, cardiac and blood disorders. Plus, they’re convenient for those on the go—unlike stationary oxygen concentrators, they’re battery-operated and don’t have to be plugged into an electrical outlet. These portal devices “give people the freedom not to be tethered to an AC-powered concentrator,” says Bob Bacheler, the Philadelphia-based managing director of Flying Angels, a company that provides non-emergency medical transport on commercial airlines.
