The SOS Groups Hyperlite 1 Portable Hyperbaric Chamber is a well designed and engineered addition to diver safety and the fast treatment of decompression illnesses. A trained team can assemble the chamber from its compact boxes to be in use in 15 mins reducing the time delay in patient treatment after diagnosis a diving injury and thereby increasing the possibility of a faster and more complete resolution of symptoms. As a DDRC Hyperbaric Instructor I have trained many teams globally in Hyperlite1 operation and emergency hyperbaric medicine, it is a major contribution to emergency diving medicine.
