Are Used To Estimate Convertibility Degree Pathologies And

are used to estimate convertibility degree Pathologies and to exclude components of a bronchial asthma. A parity from These two measurements (FEV1/FVC) expect to estimate the complex Function of lungs of the patient. At persons with COPD, FEV1 and FVC are always connected FEV1/FVC A parity and always lower than settlement for age, Floor, weights of a body, race of the patient and barometric pressure. Stages COPD Weight COPD is defined according to degree Deviations in the data (PFT), level of values of signs, Presence of accompanying diseases and conditions which can conduct To complications. According to criteria GOLD 2006 allocate four Stages COPD from 1st stage (moderate stage COPD) to IV th (very much Serious deviations from norm). Till 2006 year and the previous versions Classifications COPD the stage was used at number 0 to allocate Patients who had syndromes of chronic cough and superfluous Saliva production, but normal values PFT ().
