FIELD: medicine.
SUBSTANCE: indices of densitometry (D) in % and planimetry (P) in % are measured in both lungs, value of forced exhale during first second (VFE1) is determined in % to proper volume, discriminant equation D=0.041×VFE1+0.182×D+0.126×P is solved. If D is less than 9.43 progression of respiratory tract obstruction is predicted.
EFFECT: method allows to increase accuracy of prognosis connected with combination of chronic obstructive lung disease with bronchopulmonary dysplasias.
