Portable hyperbaric chambers, like the Hyperlite, were developed to treat decompression sickness (DCS) quickly and effectively. These lightweight chambers allow divers to receive emergency hyperbaric oxygen therapy at remote dive sites. The Hyperlite can be assembled quickly, is easy to transport, and has successfully treated various diving incidents. With the decline of traditional hyperbaric treatment facilities, portable chambers are becoming essential for ensuring divers’ safety during underwater excursions.
