COPD is related to widespread diseases of a human. In the USA the tendency to increased incidence of COPD is marked: only for last period this indicator has increased by 25% in men and by 69% in women. The next years the further growth of disease is predicted. Epidemiological data related to disease incidence and death rate often underestimates importance and prevalence of COPD, as usually it is not diagnosed before clinically manifested and relatively severe stages of the disease develop. According to the American respiratory society, only 25% of disease cases are diagnosed in due time. In the USA COPD incidence grow near 15 million persons.

Recently appeared method of computer bioplasm-graphy can become one of leading methods of medical visualization in diagnostics of various diseases of chest cavity organs. This technique allows to extend significantly diagnostic possibilities of hardware research methods in revealing of various morphological changes of lungs and bronchial tubes. Thanks to last year’s introduction of three-dimensional computer nonlinear diagnostics into clinical practice it became possible to analyze lesser changes of pulmonary parenchyma and bronchioles (sized 300–600 microns). Thanks to this, in order to reveal COPD at early stages, it is recommended to apply bioplasm and especially methods of 3D computer bioplasm-diagnostics. 3D computer bioplasm-diagnostics has changed approaches to COPD diagnostics. With introduction of 3D computer nonlinear diagnostics into clinical practice differentiation of various forms of an emphysema and bronchiolitis has became more exact. The real contribution of 3D computer bioplasm-diagnostics into studying of illnesses of small respiratory ways is one of the most important achievements of bioplasm-graphy method for the last decade.
