title: [Analysis of a pulmophonogram for assessing local pulmonary ventilation].
abstract: The method offered for pulmophonogram processing is based on definition of an easily measured simplest parameter, a relation between maximum and minimum values of the electrical signal being recorded. This value measured under different clinical conditions without considerable methodical errors is used for reliable and precise assessment of three parameters: relative local specific ventilation, relative local specific volume and local specific lung ventilation capacity. The proposed formulas of the local respiration parameters can be applied in both manual pulmophonogram processing with elementary computing aids, and in computer processing of pulmophonographic information.
