The =symptoms= that appear after decompression are vertigo, nose bleeding, nausea and vomiting. The most common symptom is the severe pains in the muscles and joints which is known by the layman as bends. There may also be temporary or permanent paralysis called diver’s palsy. In the more severe cases there will be unconsciousness, and even death. When the workman is taken too quickly from the high pressure there is formed gas and air emboli. These may form in the labyrinth of the ear, in the spinal cord, in the brain, in the heart, or in any other vital part of the body and not only be distressing but may even prove fatal. It must be remembered that the conditions produced by changes in the air pressure may be classed as traumatic, immunity from which is not entirely a question of uninterrupted transmission. If there are subluxations in the spine at the time the workman goes into the caisson, or if subluxations are produced at the time of decompression, the interference thus produced will interrupt the process of intellectual adaptation. Such subluxations should be adjusted, but it must be remembered that if emboli are formed or if bends occur the result or the relief is a question of the natural processes of Innate in the body, and the results will depend entirely upon the ability of Innate to cope with the traumatic condition. Innate Intelligence operates through the body according to law, and it is possible for the body to become so affected and deteriorated that it becomes a physical impossibility for her then to repair it and restore it to normal. We have seen that the normal air pressure at sea level is fifteen pounds to the square inch. In order that the body will not be crushed by this weight it is necessary to have an internal resistance to equal this weight. This internal resistance is maintained in the body by the tone of all of its parts; it is maintained by the expression of mental impulses in the tissue cells. We have also observed that the combining of chemicals is influenced by the pressure exerted; therefore, in order that the chemical combinations of the body be constant there must be equilibrium established between the external pressure and the internal resistance. This is maintained through the adaptability of the expression of Innate in the body. As the change takes place externally there is a corresponding adaptative change taking place internally and this all requires time. Therefore, in passing the body from one air pressure to that of another degree, there must be a sufficient amount of time intervening to allow Innate Intelligence to bring about the necessary adaptation.
