Possibilities of a computed demography method for detection of bronchoobstructive syndrome in chronic obstructive bronchitis patients and of bronchoconstriction in smokers

Abstract

The purpose of this research was to assess a significance of a computed dermography (CD) method to detect bronchoobstructive syndrome (BOS), to evaluate bronchial reversibility during a bronchodilating test in chronic obstructive bronchitis (COB) patients and to reveal bronchoconstruction in healthy smokers. Eighty four persons were observed: 30 healthy non-smokers (the control group), 24 smokers not having clinical manifestations of pulmonary diseases (the risk group), and 30 patients with COB of different seventy at the exacerbation stage. The bronchial reversibility was diagnosed using instrumental methods: CD, spirography, peakflowmetry. The CD method rejects the theory organ-point and investigates more complex relationships in contradistinction to other well-known reflex-diagnostic methods. The CD is easy, non-invasive and informative.
The control group was examined by the CD, spirography, peakflowmetry. Normal CD-criteria were found. The risk group was examined by the same methods before and in 5-10, 30-40, and 60-90 minutes after smoking. The CD method was found out to be an objective and more sensitive method which allowed to detect bronchoconstriction in smokers after smoking, while the results of the spirography and peakflowmetry were negative. The COB patients were examined before and in 30 minutes after the test with Berodual. As a result, the CD-criteria of the BOS were revealed. It was shown that the CD as more sensitive and objective method could be used equally to spirography and peakflowmetry to assess the bronchial reversibility in the COB patients and to choose bronchodilating therapy.
