Normally, you breathe 21% oxygen at sea level. Using significant pressure, Medical Grade Hard-Shell Hyperbaric chambers help the body circumvent the normal way oxygen is delivered to your body, and thereby increasing the delivery of oxygen to cells by 10, 15 or even 20 times the normal amount (200%). This is what is required to attain the benefits of Hyperbaric Oxygen Therapy.
In contrast, Soft Chambers only increase oxygen intake to 26%, just 5% more than normal, as they are unable to attain enough pressure to provide substantial benefits. Because inflatable bag chambers cannot achieve necessary pressures for healing (1.5ATA+), their use is not considered Hyperbaric Medicine.
Currently, most practitioners and companies who use, sell or lease Soft Shell Chambers feature research and scientific results that were based on TRUE clinical hyperbaric studies using ‘Hard,’ FDA approved chambers. Some inflatable bag chamber companies have even been sanctioned by the FDA for making “fraudulent medical claims.”
