Hello, As there might be a paresis of the thoracic nerve and not paralysis. Because if it s paralysis then you need to be put on ventilator support. Since there is breathing difficulties I feel there is a respiratory system pathology due to the work-related factors. Since the inspiration and expiration abilities are lowered in will advise you to look for CPAP machine with oxygen saturation machine. In fact BiPAP will be far better. This will help your pulmonary system to function close to normal and also will help the lungs fill the air. As due to the pathology there is less ability of the alveoli and needs a correction. Medicine is symptomatic and along with that a bipap machine with oxygen saturation would do good. Also try pulmonary rehabilitation under guided physiotherapist . as this will help you improve the lung capacities and help you ease of dyspnea. Its a matter of good pulmonary rehabilitation training. In my clinical experience of 12 years most patients with respiratory complications have responded well to pulmonary rehabilitation. Using of the cpap bipap and oxygen saturation is totally dependent upon the clinical findings and this machines can be used at home for large number of hours to improve the overall function of the respiratory system. Hope I have answered your query. Let me know if I can assist you further. Regards, Jay Indravadan Patel, Physical Therapist or Physiotherapist
