A recent study by the Pentagon and the Department of Veteran Affairs concluded yesterday that the use of a hyperbaric chamber did not help with mild cases of traumatic brain injury (TBI). The hyperbaric chamber is a pressurized chamber that forces oxygen into the subject's brain, and the study was conducted on tens of thousands of combat veterans of the Iraq and Afghanistan wars.
These combat veterans were 60 Marines who suffered mild brain injuries in roadside bombs and mortars or rocket-propelled grenades. According to the Pentagon, over 230,000 troops have suffered mild TBI cases since 2000.
Breathing pressurized oxygen raises the oxygen levels in the subject's brain, which boosts the health of damaged brain cells, improving brain functions and combating TBI. This system is similar to decompression chambers used on divers to combat decompression sickness and the bends.
