ANALYSING TRACHEAL SOUNDS DURING FORCED EXPIRATION TO CONFIRM OBSTRUCTION IN PATIENTS WITH BRONCHIAL ASTHMA WITH NORMAL SPIROGRAPHIC VALUES
Abstract
The paper provides analysis of tracheal sounds of forced expiration carried out on the basis of 78 cases of bronchial asthma in men aged 16-25 with normal spirographic values using authors’ technique (the control group comprised of 77 healthy non-smoking men of comparable age). The increasing duration of tracheal sounds of forced expiration observed in 41 case follow-ups (32 patients) confirms that the acoustic method is likely to be promising to diagnose bronchial obstruction in patients with bronchial asthma and normal spirographic values.
